C#: How to Serialize JSON Array data by c# on server side.

JSON: It is syntax for storing and exchanging text information. Much like XML. we can map JSON data to object.Here i have given example for mapping JSON array data to object.

Consider we have Json Array DataFormat below and we want to map these data to our StatusValueTest class:

 "[{ \"StatusValue\": \"Test1\", \"StatusValue1\": \"Test2\", \"StatusValue2\": \"Test3\", \"StatusValue3\": \"Test4\" },
 { \"StatusValue\": \"aTest1\", \"StatusValue1\": \"bTest2\", \"StatusValue2\": \"cTest3\", \"StatusValue3\": \"dTest4\"}]";

we have StatusValue ,StatusValue1, StatusValue2, StatusValue3,in array and we want to map it StatusValueTest Class data member StatusValue ,StatusValue1, StatusValue2, StatusValue3 Note: Here data member should be same as json data member otherwise it will give error.

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;

    public class StatusValueTest
    {

        public StatusValueTest()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    public string StatusValue { get; set; }

    public string StatusValue1 { get; set; }

    public string StatusValue2 { get; set; }

    public string StatusValue3 { get; set; }
    }

JavaScriptSerializer :Provides serialization and deserialization functionality for JSON data.For Mapping Between Managed Types and JSON we create first JavaScriptSerializer object and used its Deserialize  method for Deserialize Json data. See in below code:

    string strJSONData = "[{ \"StatusValue\": \"Test1\", \"StatusValue1\": \"Test2\", \"StatusValue2\": \"Test3\", \"StatusValue3\": \"Test4\" }, { \"StatusValue\": \"aTest1\", \"StatusValue1\": \"bTest2\", \"StatusValue2\": \"cTest3\", \"StatusValue3\": \"dTest4\"}]";

    JavaScriptSerializer objJavaScriptSerializer = new JavaScriptSerializer();

    StatusValueTest[] objStatus = objJavaScriptSerializer.Deserialize<StatusValueTest[]>(strJSONData);

    foreach (StatusValueTest val in objStatus)
       {
         Label1.Text += val.StatusValue;
       }
