Hi,
What is the use of DataMember in WCF? Below is the code of Declaring DataMember.Where i Can use (or) call this datamember in WCF Programming.
Can you give a simple example of using DataMember...

[DataContract]
public class MyDataContract 
{

  [DataMember]  
  public string name = "myname";
 
  [DataMember(IsRequired = true)]  
  public int age;

}

0	DataMember attribute is required to expose the data along with contract of wcf services . If you don't use [ Datamember ] , then service can't able to transfer data(properties or fields). Use Using System.Runtime.Serialization to add datamember . You can also use annotations like the below code . [DataMember(Name = "NoteID", IsRequired = true)] public int NoteID { get; set; } Suppose, you are doing a CRUD application using SQL database . Using code you have to update database , at that time you should create a class which contains all the properties (respective to your database table's column name ) then use datamember attribute .
