Solution 1

You cannot. Not that it's just impossible, the whole idea simply makes no sense. This is not how things work. This methods is executed on server side, and JavaScript — on client side.

You need to learn the basics of HTTP, Web, .NET, and only then ASP.NET. You apparently did not get it yet. Not to worry, you will learn it:

If your method is in code behind file means aspx.cs file then you can call that method using jQuery like

$(document).ready(function () {
     $.ajax({
         type: 'POST',
         url: 'Default.aspx/MethodInAspxFile',
         data: "{'param':'value'}",
         contentType: "application/json; charset=utf-8",
         dataType: "json",
         success: function (msg) {
             alert(msg);
             //do your task
         }
     });
 });

and method in your aspx.cs file looks like

//using System.Web.Services; add this namespace in aspx.cs file
[WebMethod]
public static DataSet MethodInAspxFile(string param)
{
    DataSet ds = new DataSet();
    //preform your operation here
    return ds;
}
