我正在使用 WCF4.0 模板 -REST。我正在尝试创建一种使用流上传文件的方法。

问题总是发生在

Stream serverStream = request.GetRequestStream();

流式传输类：

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;
        }
    }
}

REST 项目：

[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);
}

Windows 窗体项目：用于测试

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());
    }
}

我已关闭防火墙和 Internet 连接，但错误仍然存在。有没有更好的方法来测试上传方法？

堆栈跟踪：

在 System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress 套接字地址) 在 System.Net.ServicePoint.ConnectSocketInternal（布尔 connectFailure、Socket s4、Socket s6、Socket& 套接字、IPAddress& 地址、ConnectSocketState 状态、IAsyncResult asyncResult、Int32 超时、Exception& 异常）
