次の例では、 属性が ServiceKnownTypeAttribute 含める型を指定するインターフェイスに 属性を適用します。

// 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();
}

' interface specifying the type to include. Apply the attribute
