c# 文件传输

 

Send:

string path = "E:\\c#\\convey_file\\convey_file\\Form1.cs";                //要传输的文件
           TcpClient client = new TcpClient();
           client.Connect(IPAddress.Parse("192.168.0.52"),9999);
            FileStream file = new FileStream(path,FileMode.Open,FileAccess.Read);  //注意与receive的filestream的区别
            BinaryReader binaryreader = new BinaryReader(file);
            byte[] b = new byte[4098];
            int data;
            Console.WriteLine("正在发送文件");
            while ((data = binaryreader.Read(b, 0, 4098)) != 0)                 //这个注意是将文件写成流的形式
            {
                client.Client.Send(b,data,SocketFlags.None);           //发送文件流到目标机器
            }
           client.Client.Shutdown(SocketShutdown.Both);
           binaryreader.Close();
           file.Close();

Receive:

 

private Socket s;
        TcpListener tl;
        public void lis()
        {
            string path = "d:\\1.cs";                 //要传入文件的路径
            tl = new TcpListener(9999);
            tl.Start();
            Console.WriteLine("等待接受");
            s = tl.AcceptSocket();
            FileStream fs = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Write);   //注意这个的属性和send端有所不同
            BinaryWriter binarywrite = new BinaryWriter(fs);
            int count;
            byte[] b = new byte[4098];
            while ((count = s.Receive(b, 4098, SocketFlags.None)) != 0)             //这个是接受文件流
            {
                binarywrite.Write(b,0,count);                          //将接收的流用写成文件
            }
            binarywrite.Close();
            fs.Close();
            s.Close();
            tl.Stop();
            Console.WriteLine("文件传输完毕");
