Say we need to convert serialize C# object to JSON string and transfer that to client side to be used in Javascript. DataContract attribute is added to a class and DataMember attribute is added for all members that need be serialized.

[DataContract]
 public class Employee
    {
        #region "Private Variables"
        private string name = string.Empty;
        private string id = string.Empty;
        #endregion

        #region "Public Properties"
        [DataMember]
        public string Name
        {
            get
            {
                return this.name;
            }
            set
            {
                this.name = value;
            }
        }
        [DataMember]
        public string ID
        {
            get
            {
                return this.id;
            }

            set
            {
                this.id = value;
            }
        }
   }

Now in order to convert the above mentioned class object to JSON string use below code.

Employee obj = new Employee();
DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
using (MemoryStream ms = new MemoryStream())
 {
       serializer.WriteObject(ms, obj);
       ms.Flush();
       byte[] bytes = ms.GetBuffer();
      string jsonString = Encoding.UTF8.GetString(bytes, 0, bytes.Length).Trim('\0');
      return jsonString;
 }
