In this post, I will show you how to Built-In Logging In .NET Core. For an application, logging is very important to keep track of that application and keep it error-free.

In .NET Core, we don't need any third party logging; instead, we can use built-in logging whenever we want. This is very efficient in terms of code and performance. Now, develope a new .NET Core application and name it.

Step 1: Go to Package mManager View-->Other Windows--> Package manager Console  -->

Install-Package Microsoft.Extensions.Logging

Add Logging
Once  the extension's installed, we can add logging by adding ILogger<T> (custom logging) or ILoggerFactory. If we want to use ILoggerFactory, then we must create it using CreateLogger, to use logging add logging services under ConfigureServices. Moreover, we can use built-in logging with the other loggings (like Nlog) with very minimal code.
services.AddLogging(); 

Startup.cs
public class Startup 
    { 
        public Startup(IHostingEnvironment env) 
        { 
            var builder = new ConfigurationBuilder() 
                .SetBasePath(env.ContentRootPath) 
                .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true) 
                .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true) 
                .AddEnvironmentVariables(); 
            Configuration = builder.Build(); 
        } 
 
        public IConfigurationRoot Configuration { get; } 
 
        // This method gets called by the runtime. Use this method to add services to the container. 
        public void ConfigureServices(IServiceCollection services) 
        { 
            // Add framework services. 
            services.AddMvc(); 
            services.AddLogging(); 
        } 
 
        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. 
        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) 
        { 
            loggerFactory.AddConsole(Configuration.GetSection("Logging")); 
            loggerFactory.AddDebug(); 
 
            if (env.IsDevelopment()) 
            { 
                app.UseDeveloperExceptionPage(); 
                app.UseBrowserLink(); 
            } 
            else 
            { 
                app.UseExceptionHandler("/Home/Error"); 
            } 
 
            app.UseStaticFiles(); 
 
            app.UseMvc(routes => 
            { 
                routes.MapRoute( 
                    name: "default", 
                    template: "{controller=Home}/{action=Index}/{id?}"); 
            }); 
        } 
    } 

ILoggerFactory: We can use  ILoggerFactory. For this, we must use CreateLogger.

_logger = Mylogger.CreateLogger(typeof(HomeController)); 

HomeController.cs
public class HomeController : Controller 
    { 
        private ILogger _logger; 
 
        public HomeController(ILoggerFactory Mylogger) 
        { 
            _logger = Mylogger.CreateLogger(typeof(HomeController)); 
        } 
 
        public IActionResult Index() 
        { 
            return View(); 
        } 
 
        public IActionResult About() 
        { 
            try 
            { 
                ViewData["Message"] = "Your application description page."; 
                _logger.LogInformation("About Page has been Accessed"); 
                return View(); 
            } 
            catch (System.Exception ex) 
            { 
                _logger.LogError("About: " + ex.Message); 
                throw; 
            } 
        } 
 
        public IActionResult Contact() 
        { 
            try 
            { 
                ViewData["Message"] = "Your contact page."; 
                _logger.LogInformation("Contact Page has been Accessed"); 
                return View(); 
            } 
            catch (System.Exception ex) 
            { 
                _logger.LogError("Contact: " + ex.Message); 
                throw; 
            } 
        } 
 
        public IActionResult Error() 
        { 
            return View(); 
        } 
    } 

Run and Test

LogLevel: We can add logging level by adding the level we want in appsettings.json.Trace

• Debug
• Information
• Warning
• Error
• Application failure or crashes         
  

In this post, you will learn how to upload a file without PostBack in ASP.NET. My main focus to write this blog is that, if you work with file upload control, the page requires full PostBack and if your file upload control is inside the update panel, you must specify your submit button in trigger, as shown below.

 <Triggers> 
    <asp:PostBackTrigger ControlID=""/> 
 </Triggers> 

This also causes the full PostBack problem. To remove this problem, use "Handler" in ASP. NET C#.

UploadFile.ashx Code

 using System; 
 using System.Web; 
 using System.IO; 
 using System.Web.SessionState; 
 public class UploadFile: IHttpHandler, IRequiresSessionState { 
     public void ProcessRequest(HttpContext context) { 
         string filedata = string.Empty; 
         if (context.Request.Files.Count > 0) { 
             HttpFileCollection files = context.Request.Files; 
             for (int i = 0; i < files.Count; i++) { 
                 HttpPostedFile file = files[i]; 
                 if (Path.GetExtension(file.FileName).ToLower() != ".jpg" && 
                     Path.GetExtension(file.FileName).ToLower() != ".png" && 
                     Path.GetExtension(file.FileName).ToLower() != ".gif" && 
                     Path.GetExtension(file.FileName).ToLower() != ".jpeg" && 
                     Path.GetExtension(file.FileName).ToLower() != ".pdf" 
                 ) { 
                     context.Response.ContentType = "text/plain"; 
                     context.Response.Write("Only jpg, png , gif, .jpeg, .pdf are allowed.!"); 
                     return; 
                 } 
                 decimal size = Math.Round(((decimal) file.ContentLength / (decimal) 1024), 2); 
                 if (size > 2048) { 
                     context.Response.ContentType = "text/plain"; 
                     context.Response.Write("File size should not exceed 2 MB.!"); 
                     return; 
                 } 
                 string fname; 
                 if (HttpContext.Current.Request.Browser.Browser.ToUpper() == "IE" || HttpContext.Current.Request.Browser.Browser.ToUpper() == "INTERNETEXPLORER") { 
                     string[] testfiles = file.FileName.Split(new char[] { 
                         '\\' 
                     }); 
                     fname = testfiles[testfiles.Length - 1]; 
                 } else { 
                     fname = file.FileName; 
                 } 
                 //here UploadFile is define my folder name , where files will be store. 
                 string uploaddir = System.Configuration.ConfigurationManager.AppSettings["UploadFile"]; 
                 filedata = Guid.NewGuid() + fname; 
                 fname = Path.Combine(context.Server.MapPath("~/" + uploaddir + "/"), filedata); 
                 file.SaveAs(fname); 
             } 
         } 
         context.Response.ContentType = "text/plain"; 
         context.Response.Write("File Uploaded Successfully:" + filedata + "!"); 
         //if you want to use file path in aspx.cs page , then assign it in to session 
         context.Session["PathImage"] = filedata; 
     } 
     public bool IsReusable { 
         get { 
             return false; 
         } 
     } 
 }

    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> 
     
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

            string URLResponse = GetHtmlPage("http://www.google.com"); 
            lblResponse.Text = URLResponse; 
        } 
     
        static string GetHtmlPage(string strURL) 
        { 
     
            String strResult;

            using (StreamReader sr = new StreamReader(objResponse.GetResponseStream())) 
            { 
                strResult = sr.ReadToEnd(); 
                sr.Close();

In this code snippet, we learn how to get selected value, selected index and selected of asp dropdownlist in JavaScript. First, Create new web application in visual studio.
Now, Add one webform to application. In this tutorial we added WebForm1 in application. And Then Add on DropDownList control to webform. Design webform as follows:

<%@ Page Language="C#" AutoEventWireup="true"CodeBehind="WebForm1.aspx.cs" Inherits="DropDownListJS.WebForm1" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    var param = document.getElementById('ddlColors'); 
    document.getElementById('lblText').innerHTML = param.options[param.selectedIndex].text; 
    document.getElementById('lblValue').innerHTML = param.options[param.selectedIndex].value; 
    document.getElementById('lblIndex').innerHTML = param.options[param.selectedIndex].index; 
} 
</script> 
</head> 
<body> 
<form id="form1" runat="server"> 
<div> 
    <table> 
        <tr> 
            <td> 
                Colors 
            </td> 
            <td> 
                <asp:DropDownList ID="ddlColors" runat="server" onchange="GetListDetails()"> 
                    <asp:ListItem Text="Select" Value="0" /> 
                    <asp:ListItem Text="Red" Value="11" /> 
                    <asp:ListItem Text="Green" Value="22" /> 
                    <asp:ListItem Text="Blue" Value="33" /> 
                </asp:DropDownList> 
            </td> 
        </tr> 
        <tr> 
            <td> 
                Selecte Index :
            </td> 
            <td> 
                <label id="lblIndex">
                </label> 
            </td> 
        </tr> 
        <tr> 
            <td> 
                Selecte Text : 
            </td> 
            <td> 
                <label id="lblText"> 
                </label> 
            </td> 
        </tr> 
        <tr> 
            <td> 
                Selecte Value : 
            </td> 
           <td> 
                <label id="lblValue"> 
                </label> 
            </td> 
        </tr> 
    </table> 
</div>
</form> 
</body> 
</html> 

Next step, Run application.

Finally, Change the color.

In this post, I will tell you about how to handling JSON Arrays returned from ASP.NET Web Services with jQuery.  JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.

Using Command event over Click events give us better control over Coding as it provide proper manageable way to control events in a single module.

If we tend to had 5-6 button the rather than using 5-6 button click events we can use "Command" event. Multiple buttons will have same Command Event function but Multiple buttons cannot have same Click button event. each Click and Command Button are often related to a single button but always Click event will be fired firstly. "CommandName" property of each button must also be specified for each button.This property will decide
"what to do" in Command function this is common for multiple buttons.

Using Command event over Click events provide us better control over coding as it provide proper manageable way to control events in a single module.

Note:
"CommandName" property is important and required of buttons if we are using "Command" event. we can rename the Command Event function's name.

Follow this pattern,
    protected void Button_Command(object sender, CommandEventArgs e) 
    { 
        switch (e.CommandName) { 
            case "button1": 
                Response.Write("Click from 1"); 
                break; 
            case "button2": 
                Response.Write("Click from 2"); 
                break; 
            case "button3": 
                Response.Write("Click from 3"); 
                break; 
        } 
    }  

and in aspx file,
    <asp:Button ID="Button1" runat="server" Text="Button1" CommandName="button1" OnCommand="Button_Command" /> 
    <asp:Button ID="Button2" runat="server" Text="Button2" CommandName="button2" OnCommand="Button_Command" /> 
    <asp:Button ID="Button3" runat="server" Text="Button3" CommandName="button3" OnCommand="Button_Command" />

    List < Category > lstItems = new JavaScriptSerializer().ConvertToType < List < Category >> (data); 
    List < Product > lstprditems = new JavaScriptSerializer().ConvertToType < List < Product >> (dt); 
    string ctid = ""; 
    string ctnme = ""; 
    string pdid = ""; 
    string pdnme = ""; 
    for (int i = 0; i < lstItems.Count; i++) 
    { 
        ctid = ctid + "," + lstItems[i].categoryID; 
        ctnme = ctnme + "," + lstItems[i].categoryName; 
    } 
    for (int i = 0; i < lstprditems.Count; i++) 
    { 
        pdid = pdid + "," + lstprditems[i].productID; 
        pdnme = pdnme + "," + lstprditems[i].productName; 
    } 
    if (ctid.Length > 0) 
    { 
        ctid = ctid.Remove(0, 1); 
        ctnme = ctnme.Remove(0, 1); 
    } 
    if (ctid.Length > 0)
