[c#] What is the simplest C# function to parse a JSON string into an object?

What is the simplest C# function to parse a JSON string into a object and display it (C# XAML WPF)? (for example object with 2 arrays - arrA and arrB)

You should create a structure that represents JSON keys (in case if you exactly know it) and then you can easily deserialize JSON string into your structure. In my examle I've deserialized a response from Google Cloud Message server:

class templateResponse
{
    public String multicast_id;
    public String success;
    public String failure;
    public String canonical_ids;
    public Result[] results;

    public class Result
    {
        public String message_id;
        public String registration_id;
        public String error;
    };
}

incoming JSON was:

"\"multicast_id\":7400896764380883211,\"success\":1,\"failure\":0,\"canonical_ids\":0,\"results\":[{\"message_id\":\"0:1351777805148960%39895cf0f9fd7ecd\"}]}"

So, use

templateResponse result = new JavaScriptSerializer().Deserialize<templateResponse>(json);

and you will get deserialized result object

I would echo the Json.NET library, which can transform the JSON response into a XML document. With the XML document, you can easily query with XPath and extract the data you need. I find this pretty useful.

Just use the Json.NET library. It lets you parse Json format strings very easily:

JObject o = JObject.Parse(@"
{
    ""something"":""value"",
    ""jagged"":
    {
        ""someother"":""value2""
    }
}");

string something = (string)o["something"];

I think this is what you want:

JavaScriptSerializer JSS = new JavaScriptSerializer();
T obj = JSS.Deserialize<T>(String);
