C# 远程服务器在流传输时返回了意外响应：（400）错误请求

我在流媒体方面有问题。当我发送小文件（如1kb txt）时，一切正常，但当我发送大文件（如100KB jpg或2gb psd）时，我得到：

The remote server returned an unexpected response: (400) Bad Request.

我正在使用Windows7、VS2010和.NET3.5以及WCF服务库

我失去了整个周末的时间，我仍然看到这个错误：/请帮助我

客户：

 var client = new WpfApplication1.ServiceReference1.Service1Client("WSHttpBinding_IService1");

        client.GetString("test");
        string filename = @"d:\test.jpg";
        FileStream fs = new FileStream(filename, FileMode.Open);
        try
        {
            client.ProcessStreamFromClient(fs);

尝试设置：

<serviceDebug includeExceptionDetailInFaults="true" /> 

它不会解决问题，但您可能会收到一条错误消息，说明问题所在。

以下是错误：public void ProcessStreamFromClient（System.IO.Stream Stream）{base.Channel.ProcessStreamFromClient（Stream）；如果我的webmethod为空，则仍会出现错误。是否有任何ideaTry发送一个小文件并检查它是否仍然有效，然后尝试逐渐增大文件大小以找到限制所在。这标记为答案，但没有解释实际解决方案。错误如下：public void ProcessStreamFromClient（System.IO.Stream Stream）{base.Channel.ProcessStreamFromClient（Stream）；如果我的webmethod为空，仍然会出错。您是否有任何ideaTry发送一个小文件并检查它是否仍然有效，然后尝试逐渐增大文件大小以找到限制所在。这标记为答案，但没有解释实际解决方案。
