title: How to retrieve JSON via ASP.Net context.Request
body: <pre><code>var OrderInfo = {"ProductID": 
      "ProductIDValue",
      "ProductName": "ProductName",
      "Quantity": 1,
      "Amount": 9999,
      "SLQuantity": 9999,
      "SLDate": "08/03/2010"
  };
  
  var DTO = { 'OrderInfo': OrderInfo };
  $.ajax({
      type: "POST",
      contentType: "application/json; charset=utf-8",
      url: "JasonHandler.ashx",
      data: JSON.stringify(DTO),
      dataType: "json"
   });
  </code></pre>
  
  <p>I'm trying to retrieve posted JSON data on server side in an ASHX file via this code:</p>
  
  <pre><code>string strrequest = context.Request["OrderInfo"];
  </code></pre>
  
  <p>but it always return null. What Am I doing wrong?</p>
