在C#中增加WCF Web服务的超时

我目前有一个在服务器上调用Web服务进行搜索的应用程序.我们可以预期会返回大量数据,所以搜索花费的时间超过一分钟是常规的.

我们收到如下大量搜索的以下错误消息：

The request channel timed out while waiting for a reply after 00:00:59.7350618. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout.

这是我们已经在StackOverflow上发布的多个问题中提出的问题,不幸的是没有可用的解决方案帮助我解决了这个问题,甚至可以配置超时窗口.

我们都改变了客户端的app.config,增加了所有超时(CloseTimeout,OpenTimeout,ReceiveTimeout和SendTimeout)以及服务器上的服务的所有web.config值(closeTimeout,openTimeout和SendTimeout).

这些更改都没有任何影响,我仍然收到分钟超时.任何想法,为什么改变这些价值观会没有影响？

在下面的例子中,我们放下了时间让我们不必在测试期间等待整整一个小时.

Web.config文件：

解决方法

我认为你可能会碰到客户端请求通道的OperationTimeout,由于某些原因,通过标准配置属性不容易调整.

在调用长时间运行的操作之前,请尝试在客户端代码中：

((IContextChannel)clientProxy.InnerChannel).OperationTimeout = new TimeSpan(0,30,0); // For 30 minute timeout - adjust as necessary

其中clientProxy是服务引用生成的Client类的实例(它来自ClientBase< ISearchIndexService>).
