How to deserialize in C# something that was serialized in JQuery?

. .

It's been a while since I've done this, and I'm trying to shake off the rust.

I'm trying to set up an AJAX structure in ASP.NET using VS2010.

I have a JQuery form submit that looks something like this (greatly simplified for example purposes):

function FormSubmit () {
    $.post('SomeHandler.asmx/SomeFunction', 
        $("#form1").serialize(), 
        function(data) {some data handler}
    );
}

My "SomeHandler.asmx/SomeFunction" is a C# function that takes my form data and processes it.

To my knowledge, the SomeHandler.asmx assumes XML deserialization, but the JQuery serializes it as an HTML encoded string, not as XML.

I suppose to use an analogy, one side is speaking in English, but the other side is expecting to hear French.

How do I get around this? (For example purposes, let's say my form has a text field -- we'll call it "txtField", and a drop-down list -- let's call it "lstDropDown".)

Thanks in advance for your help!

In your asmx file make sure you use the following attribute flags on your web methods that accept and respond with json:

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string SomeWebMethod() 
{
  //blah
}

Also, make sure the web service class has the follow attribute flag:

[System.Web.Script.Services.ScriptService]
public class MyWebService : System.Web.Services.WebService
{
...
}

One last thing: if you're serializing the data on the client side, you need to use the following ajax setup:

 $.ajaxSetup({ contentType: "application/json; charset=utf-8" });
