遠程服務器返回意外響應：（400）流式傳輸時請求錯誤

Question

我有流式傳輸問題。當我送小文件中像1KB TXT一切正常，但是當我發送更大的文件中像100 KB JPG或PSD 2GB我得到：

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

我使用的是Windows 7中，VS 2010和.NET 3.5和WCF服務庫

我失去了對這個我所有的週末，我仍然看到此錯誤：/請幫我

客戶：

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); 
     } 
     catch (Exception exception) 
     { 
      Console.WriteLine(exception); 
     } 

的app.config：

和WCF ServiceLibrary：

public void ProcessStreamFromClient(Stream str) 
     { 

//error occuring even this method is empty 
      using (var outStream = new FileStream(@"e:\test.jpg", FileMode.Create)) 
      { 
       var buffer = new byte[4096]; 
       int count; 
       while ((count = str.Read(buffer, 0, buffer.Length)) > 0) 
       { 
        outStream.Write(buffer, 0, count); 
       } 
      } 
     }

Answer 1

嘗試設置：

<serviceDebug includeExceptionDetailInFaults="true" /> 

它不會解決問題，但你可能會得到一個錯誤消息指出問題所在。
