The Resource cannot be found. ASP.Net + jQuery

I am using jQuery to call a function from class L1.cs. The jQuery and function are:

     function CallData() {
        alert("hello");
       开发者_运维百科 $.ajax({
            type: "GET",
            url: "/L1/GetLocation",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function () {
                alert("Success");
            },
            error: function () {
                alert("Error");
            }
        });

The CS code

public class L1
{
    public List<Loc> GetLocation()
    {
       //some code
    }
}

For this I get an error: "The resource cannot be found." Where I am going wrong? Thanks.

I think what you are trying to setup a webservice method.

Take a look at this article, it should help explain the reasons behind the attributes http://msdn.microsoft.com/en-us/library/byxd99hx(v=VS.90).aspx

Here is what your code should look like on the CS end (assuming I typed everything correctly)

public class L1 : System.Web.Services.WebService
{
    [System.Web.Services.WebMethod()]
    public List<Loc> GetLocation()
    {
        //some code
    }
}

Edit

Alternativly you could use page methods, the syntax is similar. This will wire up some plumbing for exposing the method call to javascript.

public class L1 : Page
{
    [System.Web.Services.WebMethod()]
    public static List<Loc> GetLocation()
    {
        //some code
    }
}
