Is there is any other way deserialize JSON string,rather than using the Newtonsoft library? I've a string like 

string json = "{status : '1',message : '<tr><th>Date</th><th>Description</th><th>Reference</th>  <th>Code</th><th>Dept Code</th><th>Debit</th><th>Credit</th></tr>'}";

if i want to access the message property in code behind file, how can i do that?

You could use the DataContractJsonSerializer. Deserialize it as a class with what you want to extract, e.g.

[DataContract]
public class Message
{
    [DataMember]
    public string message { get; set; }
}

  • Which namespace do i need to use for that?thanks for your prompt answer – Arooran Dec 20 '11 at 16:26
  • DataContractJsonSerializer is in System.Runtime.Serialization.Json. DataContractAttribute and DataMemberAttribute are in System.Runtime.Serialization. The Message class can be in the namespace of your choosing. – Tim S. Dec 20 '11 at 16:27

Consider this:

You need this required namespaces:

using System.Web.Script.Serialization;

Consider this class:

[Serializable]
public class Foo
{
   public int status { get; set; }
   public string message { get; set; }
}

SerializableAttribute is required to work with JavaScriptSerializer

USAGE

JavaScriptSerializer serializer = new JavaScriptSerializer();

// Deserialize

Foo foo = serializer.Deserialize<Foo>(json);

//now you have access to...

var status = foo.status;
var message = foo.message;

You may also deserialize with JavaScriptSerializer in a Dictionary. See this:

Dictionary<string, object> ds = serializer .Deserialize<Dictionary<string, object>>(json);

var status = ds["status"].ToString();
var message = ds["message"].ToString();

  • You can't use `'` within a string, it must be escaped with `\'` – Abdul Munim Dec 20 '11 at 17:21

  1. Create class

     public class TestM
    {
        public string status { get; set; }
        public string message { get; set; }
    }

  2. Than use this in your code

     JavaScriptSerializer ser = new JavaScriptSerializer();
 TestM t =  ser.Deserialize<TestM>("{status : '1',message : '<tr><th>Date</th><th>Description</th><th>Reference</th>  <th>Code</th><th>Dept Code</th><th>Debit</th><th>Credit</th></tr>'}");
