Question

C# Socket发送文件的代码，越少越好，只要有用的代码就可以

收发文件代码都要请标明（带进度条更好），如果可用追加20分

Answer 1

以流的形式写
int port = 1234;

int port = 1234;
IPAddress ip = IPAddress.Parse("127.0.0.1");
socket = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
IPEndPoint iep = new IPEndPoint(ip,port);
//socket.Blocking = false;
socket.Bind(iep);
socket.Listen(10);
Console.WriteLine("start......");
try
{
for (int i = 0; i < 10;i++ )
{

}
}
catch
{
Console.WriteLine("异常!");
socket.Close();
}

接收端
private void Receive(Socket socket)
{
NetworkStream ns = new NetworkStream(socket);
FileStream fs = new FileStream("c:\\file.txt", FileMode.OpenOrCreate);
bool isRead = true;
while (isRead)
{
int count = ns.Read(this._receiveBuf, 0, this._receiveBuf.Length);
int datanum = 0;
datanum = BitConverter.ToInt32(this._receiveBuf, 0); //从buffer中的前4个字节读出count
if (datanum > 0) //确定每次要接受多少字节数
{
fs.Write(this._receiveBuf, 4, datanum);
}
else //如果接受字节数为0 就推出
{
isRead = false;
}
}
this.txtFile.Text = "文件传输成功";
fs.Close();
}
---------------------
发送端
private void btSend_Click(object sender, System.EventArgs e)
{
if (this._isConnect)
{
_ns = _tc.GetStream();
string path = this.txtPath.Text.Trim();
FileStream fs = new FileStream(path, FileMode.Open);
int sendCount = 0;
byte[] countbuffer = null;
byte[] clientbuffer = new byte[1004];
while (sendCount < fs.Length && _ns.CanWrite)
{
int count = fs.Read(_sendBuf, 0, _sendBuf.Length); //读出要发送的数据
countbuffer = BitConverter.GetBytes(count);
countbuffer.CopyTo(clientbuffer,0);
_sendBuf.CopyTo(clientbuffer, 4);
this._ns.Write(clientbuffer, 0, 4 + count); //写入网络流
sendCount += count;
}
countbuffer = BitConverter.GetBytes(0); //发送完文件后 发送count = 0
this._ns.Write(countbuffer, 0, countbuffer.Length); //使接收端停止
_ns.Close();
fs.Close();
}
}
