C#——文件传输

一、

1、发送端

        string path = "E:\\fuxin.txt";

TcpClient tcpClient = new TcpClient();

tcpClient.Connect(Dns.GetHostAddresses(Dns.GetHostName())[0], 50000);

FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read);

BinaryReader binaryReader = new BinaryReader(fileStream);

byte[] data = new byte[4098];

int count;

Console.WriteLine(“正在发送文件”);

while (0 != (count = binaryReader.Read(data, 0, 4098)))

tcpClient.Client.Send(data, count, SocketFlags.None);  //发送文件流到目标机器

tcpClient.Client.Shutdown(SocketShutdown.Both);

binaryReader.Close();

fileStream.Close();

Console.ReadLine();

 

2、接收端

        string path = "D:\\fuxin.cs";

TcpListener tcpListener = new TcpListener(50000);

tcpListener.Start();

Console.WriteLine(“等待接受”);

Socket socket =tcpListener.AcceptSocket();

FileStream fileStream = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Write);

BinaryWriter binaryWriter = new BinaryWriter(fileStream);

int count;

byte[] data = new byte[4098];

while (0 != (count = socket.Receive(data, 4098, SocketFlags.None)))

binaryWriter.Write(data, 0, count);//将接收的流用写成文件

binaryWriter.Close();

fileStream.Close();

socket.Close();

tcpListener.Stop();

Console.WriteLine(“文件传输完毕”);

Console.ReadLine();

 

 

二、用Socket实现

1、发送端

        string path = "E:\\fuxin.txt";

Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

socket.Connect(Dns.GetHostAddresses(Dns.GetHostName())[0], 50000);

FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read);

BinaryReader binaryReader = new BinaryReader(fileStream);

byte[] data = new byte[4098];

int count;

Console.WriteLine(“正在发送文件”);

while (0 != (count = binaryReader.Read(data, 0, 4098)))

socket.Send(data, count, SocketFlags.None);  //发送文件流到目标机器

socket.Shutdown(SocketShutdown.Both);

binaryReader.Close();

fileStream.Close();

Console.ReadLine();

 

2、接收端

        string path = "D:\\fuxin.cs";

IPEndPoint ipep = new IPEndPoint(Dns.GetHostAddresses(Dns.GetHostName())[0], 50000);

Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

socket.Bind(ipep);

socket.Listen(10);

Console.WriteLine(“等待接受”);

Socket newsocket = socket.Accept();

FileStream fileStream = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Write);

BinaryWriter binaryWriter = new BinaryWriter(fileStream);

int count;

byte[] data = new byte[4098];

while (0 != (count = newsocket.Receive(data, 4098, SocketFlags.None)))

binaryWriter.Write(data, 0, count);//将接收的流用写成文件

binaryWriter.Close();

fileStream.Close();

socket.Close();

newsocket.Close();

Console.WriteLine(“文件传输完毕”);

Console.ReadLine();

 

3、发送端另一种精简版

            string path = "E:\\fuxin.txt";

Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

socket.Connect(Dns.GetHostAddresses(Dns.GetHostName())[0], 50000);

Console.WriteLine(“正在发送文件”);

socket.SendFile(path);

socket.Shutdown(SocketShutdown.Both);
