Enum?

Enum?

• TX Gal

  Instead of DataMember Attribute, use EnumMember Attribute to specify members of enum. From Feb CTP, only if you use EnumMemberAttribute, your enums are created properly in proxy.

  A related/extended question on the above.. I have a similar situation where my Enum has no values in the generated proxy code. However, my enum is not directly referenced by any of the OperationContract methods: it is a nested member of the DataContract class. For example:

  public enum MyEnum : int
  {
  SomeValue,
  SomeOtherValue
  }

  [DataContract]
  public class MyData
  {
  [DataMember]
  public MyEnum value
  { get { ...} set { ... } }
  }

  [ServiceContract]
  public class ServiceClass
  {
  [OperationContract]
  public MyData GetData()
  { ... }
  }

  As you can see, the ServiceClass doesn't directly reference the enum class, but the serialisation of the class is required in order to complete the call. I've tried this with various combinations of DataContract, DataMember, and EnumMember attributes to no avail. How should this enum be marked up so that it will be correctly generated in the proxy code

  The problem seems to have resolved itself now... I cleared the solution and re-got everything from source control, and I'm no longer getting the same problem. I guess it was a dirty build issue somewhere, though I'm still not sure what caused it.

  Cheers for the help!

  that did the trick,

  thanks a lot.

  //If one of the service contract has reference to Enum types(Parameters or return value),svcutil will import enum types to client side proxy

  //Simple Enum decalaration should be enough

  Public Enum Seasons As Integer

  Summer = 1

  Winter = 2

  Spring = 3

  Autumn = 4

  End Enum

  <OperationContract()> _

  Sub GetEnum(ByVal enm As Seasons)
