WCF協定可以使用多個回調接口嗎？

Question

我想是這樣的：

[ServiceContract (
    CallbackContract = typeof (CallbackContract_1), 
    CallbackContract = typeof (CallbackContract_2), 
    CallbackContract = typeof (CallbackContract_3)) 
] 
public interface SomeWcfContract { 

我知道這並不喜歡這個工作。是否還有辦法讓單個合約使用多個回調接口？

Answer 1

服務合同只能指定 回調合同，如果合同中 是合同的 自己的基地契約中定義的所有回調 合同的子接口。

interface ICallbackContract1 
{...} 

interface ICallbackContract2 : ICallbackContract1 
{...} 

[ServiceContract(CallbackContract = typeof(ICallbackContract1))] 
interface IMyBaseContract 
{...} 

[ServiceContract(CallbackContract = typeof(ICallbackContract2))] 
interface IMySubContract : IMyBaseContract 
{...} 

或

interface ICallbackContract1 
{...} 
interface ICallbackContract2 
{...} 
interface ICallbackContract3 : ICallbackContract2,ICallbackContract1 
{...} 

[ServiceContract(CallbackContract = typeof(ICallbackContract1))] 
interface IMyBaseContract1 
{...} 
[ServiceContract(CallbackContract = typeof(ICallbackContract2))] 
interface IMyBaseContract2 
{...} 
[ServiceContract(CallbackContract = typeof(ICallbackContract3))] 
interface IMySubContract : IMyBaseContract1,IMyBaseContract2 
{...}
