WCF: DataMember attribute on property vs. member

Question

In wcf, what is the difference between applying the DataMember attribute on a property

private int m_SomeValue;

[DataMember]  
public int SomeVal         


        

Answer 1

If add [DataMember] on private int m_SomeValue, this member can not be serialization,so must be add it on public int SomeValue.

[DataMember]  
private int m_SomeValue;

public int SomeValue {
  get {...}
  set {...}
}

the code of above can not be get value in the client if you use it through WCF.
