C# JSON to LIST extension method

Question

From Scottgu's post i got the code to Serialize a collection to JSON object.(i)How to convert the JSON object back to List? (ii) I did not find JavaScriptserializer in System.Runtime.Serialization will the only code work for VS 2010?

ScottGu's snippet

namespace ScottGuHelper.JSON
{
  public static class JSONHelper
  {
      public static string ToJSON(this object obj)
      {
        JavaScriptserializer serializer=new JavaScriptserializer();
        return serializer.serialize(obj);
      }

     public static string ToJSON(this object obj,int recursionDepth)
     {
       JavaScriptserializer serializer=new Javascriptserializer();
       serializer.RecursionLimit=recursionDepth;
       return serializer.serialize(obj); 
     }

 }
}

Answer 1

Reference System.Web.Extensions.dll. It is in the System.Web.Script.Serialization namespace. On the MSDN page for JavaScriptSerializer you'll see where it is located and for which versions of .NET it is available.

Answer 2

Have a look to the Deserialize method of the same JavascriptSerializer class.

The class is in the System.Web.Script.Serialization namespace

You can find a good example of usage here on SO

Answer 3

Refer System.Web.Script.Serialization for JavaScriptSerializer.

Write an extension method to call Deserialize the object.

    public static T JSONtoList<T>(this object jsonObj)
    {
        JavaScriptSerializer _jsserializer = new JavaScriptSerializer();
        return _jsserializer.Deserialize<T>(jsonObj as string);
    }

Hope this helps.(Code is not tested).
