Asp.Net Returning Custom Object in json

Question

I have a class CodeWithMessage that I want to return from my webservice as json.

The class is defined as such

namespace UserSite //Classes For my site
{
 namespace General
 {
 public class CodeWithMessage
 {
 private int iCode = 0;
 private string sMessage = "";
 public CodeWithMessage(int Code, string Message)
 {
 iCode = Code;
 sMessage = Message;
 }
 public CodeWithMessage()
 {
 }
 public void Message(string lMessage)
 {
 sMessage = lMessage;
 }
 public void Code(int lCode)
 {
 iCode = lCode;
 }
 }

In the Webservice I have

[WebMethod(Description = "Creates A New Blog.")]
 [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
 public CodeWithMessage AddNewBlog(string sTitle, string sDescription, string sOohrl, int iCategory=30)
 {
 CodeWithMessage CWM;
 CWM = new CodeWithMessage();
 CWM.Message("That url Is In Use");
 CWM.Code(0);
 return CWM;

I am posting the correct values (I truncated the function but it's getting what it needs and executing) I get back

{"d":{"__type":"UserSite.General.CodeWithMessage"}}

I'm not sure why I am not getting back an actual json object with the values but rather just the class name?? I thought asp.net would automatically serialize the object? Does it not??

Thanks in advance

You have to use public properties for the JavaScriptSerializer to serialize the JSON like you want. The JavaScriptSerializer cannot expose the methods nor the private fields.

namespace UserSite //Classes For my site
{
 namespace General
 {
 public class CodeWithMessage
 { 
 public int Code { get; set; }
 public string Message { get; set; }
 }
 }
}
..............
//usage
CodeWithMessage CWM = new CodeWithMessage();
CWM.Message = "That url Is In Use";
CWM.Code = 0;
return CWM;
