<p>I'm using WCF4.0 template -REST. I'm trying to create a method to upload files using a stream.</p> <p>问题总是发生在</p> <pre class="brush:php;toolbar:false;">Stream serverStream = request.GetRequestStream();</pre> <p>流式传输类：</p> <pre class="brush:php;toolbar:false;">namespace LogicClass { public class StreamClass : IStreamClass { public bool UploadFile(string filename, Stream fileStream) { try { FileStream fileToupload = new FileStream(filename, FileMode.Create); byte[] bytearray = new byte[10000]; int bytesRead, totalBytesRead = 0; do { bytesRead = fileStream.Read(bytearray, 0, bytearray.Length); totalBytesRead = bytesRead; } while (bytesRead > 0); fileToupload.Write(bytearray, 0, bytearray.Length); fileToupload.Close(); fileToupload.Dispose(); } catch (Exception ex) { throw new Exception(ex.Message); } return true; } } }</pre> <p>REST 项目：</p> <pre class="brush:php;toolbar:false;">[WebInvoke(UriTemplate = "AddStream/{filename}", Method = "POST", BodyStyle = WebMessageBodyStyle.Bare)] public bool AddStream(string filename, System.IO.Stream fileStream) { LogicClass.FileComponent rest = new LogicClass.FileComponent(); return rest.AddStream(filename, fileStream); }</pre> <p>Windows 窗体项目：用于测试</p> <pre class="brush:php;toolbar:false;">private void button24_Click(object sender, EventArgs e) { byte[] fileStream; using (FileStream fs = new FileStream("E:\stream.txt", FileMode.Open, FileAccess.Read, FileShare.Read)) { fileStream = new byte[fs.Length]; fs.Read(fileStream, 0, (int)fs.Length); fs.Close(); fs.Dispose(); } string baseAddress = "http://localhost:3446/File/AddStream/stream.txt"; HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(baseAddress); request.Method = "POST"; request.ContentType = "text/plain"; Stream serverStream = request.GetRequestStream(); serverStream.Write(fileStream, 0, fileStream.Length); serverStream.Close(); using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) { int statusCode = (int)response.StatusCode; StreamReader reader = new StreamReader(response.GetResponseStream()); } }</pre> <p>我已关闭防火墙和 Internet 连接，但错误仍然存在。Is there a better way to test the upload method? </p> <p>Stack trace: </p> <blockquote> <p>At System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socket address) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception)</p> </blockquote><p><br /></p>
