1、利用socket 套接字來進行文件傳輸速度還行，有需要完整版的可以聯系我，免費公布。具體代碼：using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Net;using System.Net.Sockets;using System.IO;using System.Threading;namespace 發送文件

2、 public partial class Form1 : Form public Form1() CheckForIllegalCrossThreadCalls = false; InitializeComponent(); private Socket socket; private Thread a, b; private string filename; private TcpListener listen; private void start() listen = new TcpListener(14); listen.Start(); while (true) Socket s

4、.Unicode.GetString(bytes, 0, x).Split('|'); int length = int.Parse(mes0); SaveFileDialog sf = new SaveFileDialog(); sf.FileName = mes1; if (sf.ShowDialog() = DialogResult.OK) FileStream fs = new FileStream(sf.FileName, FileMode.Create, FileAccess.Write); BinaryWriter bw = new BinaryWriter(fs

5、); int total = 0; x = 0; while (total < length) x = ns.Read(bytes, 0, bytes.Length); bw.Write(bytes,0,x); total += x; bw.Close(); ns.Close(); fs.Close(); s.Close(); MessageBox.Show("ok"); catch (Exception ee) MessageBox.Show(ee.ToString(); private void button1_Click(object sender, Event

6、Args e) TcpClient client = new TcpClient(textBox1.Text.Trim(), 14); NetworkStream ns = client.GetStream(); OpenFileDialog aa = new OpenFileDialog(); if(aa.ShowDialog() = DialogResult.OK) string ss = aa.FileName.Split(''); filename = ssss.Length - 1; FileStream fs = new FileStream(aa.FileName

7、,FileMode.Open,FileAccess.Read); BinaryReader br = new BinaryReader(fs); Int64 size = fs.Length; MessageBox.Show(size.ToString(); byte bytes = new byte1024*1024; bytes = Encoding.Unicode.GetBytes(size.ToString()+'|'+filename+'|'); ns.Write(bytes,0,bytes.Length); Int64 total = 0; while (total < size) int x = br.Read(bytes,0,bytes.Length); ns.Write(bytes,0,x); total += x; private void F
