Question

I have a WCF service with 3 string arguments. Calling this with jQuery and JSON does reach my method but only 1 of the arguments contain a value – the others are received null, even though they are passed. Any thoughts why?

[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
    public string Save(string site, string title, string contentType)
    {
        // method...
    }

JS:

                    $.ajax(
                      {
                        type: "POST",
                        url: "/Service.svc/Save",
                        dataType: "json",
                        data: "{\"title\": \"title...\", \"site\": \"site...\", \"contentType\": \"contentType...\"}",
                        contentType: "application/json; charset=utf-8",
                        success: function(data) {
                        },
                        error: function() {
                          alert("Sorry, an error has occured");
                        }
                      }

False alarm.

The argument name for those two missing arguments was different in the ServiceContract to the service. I was using the argument name that was in the service, not the one in the ServiceContract. Stupid.

Thanks for the replies guys.
