我已经看过有关如何转换为代理的参考资料，例如：
((IContextChannel)client.InnerChannel).OperationTimeout = new TimeSpan(0,0,240);
设置operationtimeout但我使用的是client = channelFactory.CreateChannel（）;
如何将频道投射到IContextChannel？我希望这是有道理的。我没有完全掌握WCF中的频道。
由于
克塞，
不确定如何实施您的建议。 在这段代码中，我如何设置operationtimeout？

通过将通道工厂转换为通道接口，您将不会得到任何有用的（非空/非异常）结果，因为工厂没有必要实现任何通道接口。
您可以将频道投射到其他频道界面，如果您知道所使用的频道类型（例如您所参考的代码），则可能会获得有用的结果。
编辑：我认为((IContextChannel)channel).OperationTimeout = new TimeSpan(0,10,0);应该有效。
注意：您帖子的标题与您的代码不符......
