示例1: typeof
// 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", typeof(Helper))]
[ServiceContract()]
public interface ICatalog
{
// Any object type can be inserted into a Hashtable. The
// ServiceKnownTypeAttribute allows you to include those types
// with the client code.
[OperationContract]
Hashtable GetItems();
}
// This class has the method named GetKnownTypes that returns a generic IEnumerable.
static class Helper
{
public static IEnumerable<Type> GetKnownTypes(ICustomAttributeProvider provider)
{
System.Collections.Generic.List<System.Type> knownTypes =
new System.Collections.Generic.List<System.Type>();
// Add any types to include here.
knownTypes.Add(typeof(Widget));
knownTypes.Add(typeof(Machine));
return knownTypes;
}
}
[DataContract()]
public class Widget
{
[DataMember]
public string Id;
[DataMember]
public string Catalog;
}
[DataContract()]
public class Machine : Widget
{
[DataMember]
public string Maker;
}示例2: GetItems
// Apply the ServiceKnownTypeAttribute to the
// interface specifying the type to include. Apply
// the attribute more than once if needed.
[ServiceKnownType(typeof(Widget))]
[ServiceKnownType(typeof(Machine))]
[ServiceContract()]
public interface ICatalog2
{
// Any object type can be inserted into a Hashtable. The
// ServiceKnownTypeAttribute allows you to include those types
// with the client code.
[OperationContract]
Hashtable GetItems();
}
