示例1: method
' Define a service contract and apply the ServiceKnownTypeAttribute
' to specify types to include when generating client code.
' The types must have the DataContractAttribute and DataMemberAttribute
' applied to be serialized and deserialized. The attribute specifies the
' name of a method (GetKnownTypes) in a class (Helper) defined below.
<ServiceKnownType("GetKnownTypes", GetType(Helper)), ServiceContract()> _
Public Interface ICalculator
' Any object type can be inserted into a Hashtable. The
' ServiceKnownTypeAttribute allows you to include those types
' with the client code.
<OperationContract()> _
Function GetItems() As Hashtable
End Interface
' This class has the method named GetKnownTypes that returns a generic IEnumerable.
Friend Class Helper
Public Shared Function GetKnownTypes(provider As ICustomAttributeProvider) _
As IEnumerable(of Type)
Dim knownTypes As List(Of Type) = New List(Of Type)
' Add any types to include here.
knownTypes.Add(GetType(Widget))
knownTypes.Add(GetType(Machine))
Return knownTypes
