Trying to parse data from a website and deserializing it in C#

I'm trying to parse data from my website and then deserializing it inside C# but I haven't gotten it work. What is the simplest way and method to use when grabbing dat开发者_如何学运维a from a http source and deserializing it in C#?

Based on the following JSON:

{
  name: "Brad Christie",
  score: 10,
  questions: [
    {
      question_id: 1,
      question: "How do I deserialize javascript?",
      answer: "JavaScriptSerializer",
      points: 10
    }
  ]
}

and assuming these classes:

public class Question
{
  public Int32 question_id;
  public String questions;
  public String answer;
  public Int32 points;
}

public class JSExample
{
  public String name;
  public Int32 score;
  IEnumerable<Question> questions;
}

the below should work (though didn't test and going by memory of what I've done in the past). Basically, the JavaScriptSerializer should take a JSON string and parse it out in to your custom object, or result in a dictionary of the structure of the JSON (I personally prefer placing it an object so i can manipulate it as I chose, but you can use the dictionary/dynamic variable and debug to see the result). Anyways, the code would be as follows:

//String the_JSON_string = <data from webpage>;
JavaScriptSerializer serializer = new JavaScriptSerializer();
JSExample example = serializer.Deserialize<JSExample>(the_JSON_string);

There are a number of JSON serializers in .NET. Most notably the built in DataContractSerializer
