winfrom+Fleck 上传文件

article/2025/10/6 5:48:07

最近这个项目要做一个Winfrom上传Execl到服务器。

就想到之前用Fleck做的一个小功能，但是客户端Web端的。百度吧，看有没有办法，开始找到fw4 ，但是要引用它的dll，是可以，继续找了会结果找到ClientWebSocket，只需要using System.Net.WebSockets;就好了，想着去试试。

网上很多Fleck的例子，server.Start 中只需要加上 socket.OnBinary = file =>{......}，具体后面有图。

下面是客户端的：

ClientWebSocket ws = new ClientWebSocket();
//创建WebSocket
static string IP = ConfigurationManager.AppSettings["IP"];
static string Point = ConfigurationManager.AppSettings["Point"];
string url = "ws://"+ IP + ":"+ Point;

连接ws：

async void ClientWebSocketConnect(){try{if (ws.State != WebSocketState.Open){ws = new ClientWebSocket();await ws.ConnectAsync(new Uri(url), CancellationToken.None);ArraySegment<byte> bytesReceived = new ArraySegment<byte>(new byte[100]);WebSocketReceiveResult result = awaitws.ReceiveAsync(bytesReceived, CancellationToken.None);var str = Encoding.UTF8.GetString(bytesReceived.Array, 0, result.Count);label1.ForeColor = System.Drawing.Color.Green;label1.Text = str;}else{await ws.ConnectAsync(new Uri(url), CancellationToken.None);}}catch(Exception ex){label1.Text = ex.Message;}}

        /// <summary>/// 关闭断开/// </summary>async void ClientWebSocketClose(){if (ws.State == WebSocketState.Open || ws.State == WebSocketState.CloseReceived){await ws.CloseAsync(WebSocketCloseStatus.NormalClosure, "用户关闭", CancellationToken.None);ws.Dispose();}}

另外给Form1_FormClosing事件加了关闭连接，不然线程一直在，每次重启服务端就重新连接了。

用OpenFileDialog选择一个execl，上传

        /// <summary>/// 上传文件/// </summary>async void UpFile(){if (ws.State == WebSocketState.Open){// 用文件流打开用户要发送的文件；using (FileStream fs = new FileStream(txtSelectFile.Text, FileMode.Open)){//获取文件的名称和扩展名  string fileName = System.IO.Path.GetFileName(txtSelectFile.Text);//文件的名称转byte[] 利用了web上面url编码的功能，带了编码，避免二进制过来汉字乱码byte[] arrfileName = System.Web.HttpUtility.UrlEncodeToBytes(fileName, Encoding.GetEncoding("GB2312"));//string//分隔符byte[] arr_fgf = System.Text.Encoding.UTF8.GetBytes("|");//定义数组 赋值计算总长度byte[] arrFile = new byte[fs.Length + arrfileName.Length + arr_fgf.Length];//组装字符串的方式//把arrfileName复制到arrFileArray.Copy(arrfileName, arrFile, arrfileName.Length);//把arr_fgf复制到arrFile，在arrfileName之后Array.Copy(arr_fgf, 0, arrFile, arrfileName.Length, arr_fgf.Length);//把文件流写入arrFile指定位置fs.Read(arrFile, (arrfileName.Length + arr_fgf.Length), (arrFile.Length - arrfileName.Length - arr_fgf.Length));  // 将文件中的数据读到arrFile数组中；//以二进制方式发送WebSocketvar buffer = new ArraySegment<byte>(arrFile);await ws.SendAsync(buffer, WebSocketMessageType.Binary, true, CancellationToken.None);//清理控件txtSelectFile.Clear();//while (true)//{ArraySegment<byte> bytesReceived = new ArraySegment<byte>(new byte[100]);//接收数据WebSocketReceiveResult result = await ws.ReceiveAsync(bytesReceived, CancellationToken.None);//byte[]转stringvar str = Encoding.UTF8.GetString(bytesReceived.Array, 0, result.Count);//if (str.Length > 0)//{if(str.Contains("上传成功"))label1.ForeColor = System.Drawing.Color.Green;elselabel1.ForeColor = System.Drawing.Color.Red;label1.Text = str;//    return;//}//}}}}

这句是核心，选用二进制的方式
