PeterToday, I will show you How to Post Multiple JSON Objects to Ajax Method in C#.
C# web method
[System.Web.Services.WebMethod]
public static void Post(object data, object dt)
{
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)
{
pdid = pdid.Remove(0, 1);
pdnme = pdnme.Remove(0, 1);
}
}
