asp.net使用Socket.Send发送信息及Socket.SendFile传输文件的方法

本文实例讲述了asp.net使用socket.send发送信息及socket.sendfile传输文件的方法。分享给大家供大家参考，具体如下：

// displays sending with a connected socket
// using the overload that takes a buffer.
public static int sendreceivetest1(socket server)
{
  byte[] msg = encoding.utf8.getbytes("this is a test");
  byte[] bytes = new byte[256];
  try
  {
    // blocks until send returns.
    int i = server.send(msg);
    console.writeline("sent {0} bytes.", i);
    // get reply from the server.
    i = server.receive(bytes);
    console.writeline(encoding.utf8.getstring(bytes));
  }
  catch (socketexception e)
  {
    console.writeline("{0} error code: {1}.", e.message, e.errorcode);
    return (e.errorcode);
  }
  return 0;
}

// establish the local endpoint for the socket.
iphostentry iphost = dns.gethostentry(dns.gethostname());
ipaddress ipaddr = iphost.addresslist[0];
ipendpoint ipendpoint = new ipendpoint(ipaddr, 11000);
// create a tcp socket.
socket client = new socket(addressfamily.internetwork, sockettype.stream, protocoltype.tcp);
// connect the socket to the remote endpoint.
client.connect(ipendpoint);
// there is a text file test.txt located in the root directory.
string filename = "c:\\test.txt";
// send file filename to remote device
console.writeline("sending {0} to the host.", filename);
client.sendfile(filename);
// release the socket.
client.shutdown(socketshutdown.both);
client.close();
