Pass json object as parameter in c# method

Question

I am getting the facebook data of the user using the facebook api as follow:

 function testAPI() {
            FB.api('/me?fields=id,name, birthday, picture.width(100).height(100), email', function (response) {
                if (response && !response.error)
                    //console.log(response);
                    buildProfile(response);
            })
        }

Now I want to pass the response json object to a method in c# as parameter. For doing that I am using the ajax as follows:

function buildProfile(user) {
            $.ajax({
                url: 'callback.aspx/SaveData',
                data: JSON.stringify(user),
                dataType: "json",
                type: "POST",
                contentType: "application/json; charset=utf-8",
                success: function (result) {
                }
            });
        }

There is method with name SaveData in c#, I have setup a breakpoint on that method.

The url: 'callback.aspx/SaveData' defined above should I have called the callback.aspx page in which SaveData method is present. But somehow I am not able to redirect to the page callback.aspx and to method SaveData in c#.

 public void SaveData(List<string> strings)
 {
            string text = "";
 }

Any help will be greatly appreciated. Thanks in advance.

"But somehow it is not working." What does that mean? An exeption? Unexpected behaviour? — MakePeaceGreatAgain

If you don't post the not working method how can we help you? — Marco Salerno

I think you'd need your controller to accept a CLASS which matches the user object in terms of fields available, and not Json.stringify the data - just pass the user object as-is. Then it should work. At the moment MVC is probably trying to find an Action that expects a single string param and failing, so it's not calling the action on the controller. — GPW

Please share your C# method. Are you using Webform or mvc or web service? — Noor All Safaet

[WebMethod]
public void SaveData(List<string> strings)
{
      string text = "";
}

The specific method being called needs an attribute WebMethod to be defined to be called using an ajax, I don't see the attribute in your case.
