当返回的消息较大时，WCF调用超时

我们有一个系统，其中一个客户端flash应用程序调用一个基于asmx的搜索web服务，而该web服务又使用NetTcpBinding调用托管在windows服务中的wcf服务。当搜索结果的数量很小时，这种方法可以很好地工作。但当搜索结果越来越大，在2000条记录范围内时，我们在asmx服务中遇到了一个例外，它调用wcf：

`The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state.`

为了排除错误，我们启用了服务跟踪，发现报告的错误为：

`The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:01:00'.` 

我们增加了服务器和客户端配置中的超时值，还增加了maxItemsInObjectGraph值。wcf调用没有发生错误，因为我们可以对其进行调试，观察到的行为是，当wcf调用返回时，asmx服务中的代码命中异常块并报告上述错误

用于从asmx服务调用wcf的代码：

List<***.SearchResult> results;
    using (var searchFactory = new ChannelFactory<***.ISearch>("NewSearch"))
    {
        Legacy.ISearch searchProxy = searchFactory.CreateChannel();
        results = searchProxy.Search(searchOption);
    }

列出结果；
使用（var searchFactory=newchannelfactory（“NewSearch”））
{
Legacy.ISearch searchProxy=searchFactory.CreateChannel（）；
结果=searchProxy.Search（searchOption）；
}

此调用正在报告异常

即使在增加配置中的阈值之后，我们也不确定为什么会出现超时问题。可能是因为服务没有获取我们的绑定配置并使用一些默认配置值，因此抛出了错误。不确定如何验证服务是否在运行时实际获取了我们的配置。

需要帮助解决此问题。

您必须在应用程序中使用绑定，但仅声明绑定，请使用

bindingConfiguration

属性

<endpoint address="net.tcp://localhost:8228/SearchController" binding="netTcpBinding" contract="***.ISearch" name="SearchController" bindingConfiguration="LargeMessageBinding" />

和<代码> bdIdgStase=“Client MexEng绑定”< /C> >客户端配置也
