WCF Serialization

Is it also possible to serialize a method using WCF. For type [DataContract] needs to be used and for members [DataMember] should be used.

Code:

---

  [DataContract]
  public class User {

      [DataMember]
      public string Name {
        get;
        set;
      }

      //I want to to the same thing here
      public override string ToString() {
        return "Hello";
      }
  }

---

Note. This is not the service but a type that is passes by the service.

Is this possible for a method. Or do I need to do this using the service itself?

No, it isn't. And it doesn't make sence to have such an ability, because passing methods would break encapsulation.
