Parsing JSON POST request C#

Question

Some serwer sends POST requests with the following information:

{
    payload: {
    uid: "900af657a65e",
    amount: 50,
    adjusted_amount: 25
},
 signature: "4dd0f5da77ecaf88628967bbd91d9506"
}

How shoud I successfully process that in my ASHX handler?

So what is it? In the 'documentation' example in Ruby I see that they use the JSON library to parse this — user2441297, Jun 20 '13 at 19:03
OK. Lets assume that this is JSON and I know how to parse JSON string. How do I get this string from the POST request? I don't have any POST parameter specified which holds it(context.Request["????"]) — user2441297, Jun 20 '13 at 19:16
http://jsonlint.com/ will tell you what's wrong with it -- as Mike noted, the keys need to be quoted strings, not bare identifiers. — Ryan M, Jun 20 '13 at 19:17
@user2441297 I edited my answer with some code to read the request body using context.Request.InputStream. — Ryan M, Jun 20 '13 at 19:31

As SLaks noted, that's not valid JSON. But in general, a good solution for serializing/deserializing JSON in .NET is the JSON.NET library: http://json.codeplex.com/. There is plenty of documentation there that should get you started.

Edit: to read the request body, try something like

 string postData = new System.IO.StreamReader(context.Request.InputStream).ReadToEnd();
