大二进制文件（byte []）通过WCF传输文件
|
我正在尝试构建一个WCF服务，该服务允许我将大型二进制文件从客户端发送到该服务。
但是，我只能成功传输最大3-4MB的文件。 （尝试传输4.91MB时，我失败了，当然，超出范围的话）
如果尝试发送4.91MB文件，则会收到以下错误消息：
异常消息：收到对http：// localhost：56198 / Service.svc的HTTP响应时发生错误。这可能是由于服务端点绑定未使用HTTP协议。这也可能是由于服务器终止了HTTP请求上下文（可能是由于服务关闭了）。有关更多详细信息，请参见服务器日志。
内部异常消息：基础连接已关闭：接收时发生意外错误。
内部异常消息：无法从传输连接读取数据：远程主机强行关闭了现有连接。
内部异常消息：远程主机强行关闭了现有连接
将byte []文件作为方法参数发送到公开的服务方法后，就会在客户端发生此错误。
我在服务方法的第一行有一个断点，如果成功进行文件传输（3MB以下），则会遇到断点并传输文件。但是，在这种情况下，一旦调用该方法，就会出现错误。如果发生此错误，则不会在服务中设置断点。
我将粘贴“服务Web.config”和“ Asp页面（客户端）Web.config”的各个部分。如果您还需要发送文件并接受文件的代码，请告诉我，我也将发送该文件。

和设置。<binding name=\"Streaming_Binding\" maxReceivedMessageSize=\"67108864\" messageEncoding=\"Text\" textEncoding=\"utf-8\" transferMode=\"Streamed\"> </binding>[OperationContract] public Stream GetLargeFile() { return new FileStream(path, FileMode.Open, FileAccess.Read); } [OperationContract] public void SendLargeFile(Stream stream) { // Handle stream here - e.g. save to disk ProcessTheStream(stream); // Close the stream when done processing it stream.Close(); }public Stream GetLargeFile() { var client = /* create proxy here */; try { var response = client.GetLargeFile(); // All communication is now handled by the stream, // thus we can close the proxy at this point client.Close(); return response; } catch (Exception) { client.Abort(); throw; } } public void SendLargeFile(string path) { var client = /* create proxy here */; client.SendLargeFile(new FileStream(path, FileMode.Open, FileAccess.Read)); }磐剩
