What is the process for transforming the result of a .aspx file into a JSON format?

Question

What is the process for transforming the result of a .aspx file into a JSON format?

I am trying to convert the output of an .aspx page into a JSON object in order to accommodate a JSONP Ajax request.

Here is what's happening on the page:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="mypage.aspx.cs" Inherits="folder_mypage" %>

<div class="myClass">Hello</div>

After making an ajax call using jQuery:

$.ajax({
    url: 'http://myownajax.projects.it/folder/mypage.aspx',
    dataType: 'jsonp',
    success: function(result) {
        console.log("Request successful!");
    },

    error: function(jqXHR, textStatus, errorThrown) {
        console.log(textStatus + " - " + errorThrown);
    }                
});

The error message I receive is

parsererror - SyntaxError: class is a reserved identifier

This is why I need to transform "the output of the page" into a JSON element.

Can someone guide me on how to achieve this?

EDIT To simplify: I want to add an .aspx context to an element on the client side! As the request involves cross-domain interaction and requires JSONP, which relies on JSON as its output. Hence, my goal is simply to take the HTML (in string format) and store it in a JSON object. For example:

result.myHtmlString="<div class='myClass'>Hello</div>";

If you wanted to implement something similar, here's a basic representation of how it could be done (note: unverified code, just for demonstration purposes and showcasing the use of js-serializer).

class Data{
  public String Content{get;set;}
}

TextReader reader = new TextReader("file.html");
string content = reader.ReadToEnd();
var data = new Data(){Content=content};
JavaScriptSerializer serializer = new JavaScriptSerializer();
var jsonData = serializer.Serialize(data);

Alternatively, without using Serializer:

String content = new TextReader("file.html").ReadToEnd();
String jsonData = "{ Content: '" + content + "'}";
return jsonData;

Note that the final output 'jsonData' is in string format!

It's important to recognize that your output page is not formatted in JSON, but instead in HTML:

<div class="myClass">Hello</div>

If it were in JSON format, it would look something like this:

{
    "div": 
    { 
        myclass: "John"
    },
    ...
}

Consider moving your logic to the backend code or exploring methods for rendering.
At the moment, it's unclear what your goal is - are you aiming to deliver HTML as JSON?

UPDATE: To send HTML back to the client, you can encapsulate it similarly to this:

{
    html: "YOUR RESULT HTML HERE"
}
