TcpClient 读写流

TcpClient tcp = new TcpClient();
tcp.Connect(IPAddress.Parse("192.168.1.161"), 8885);//根据服务器的IP地址和侦听的端口连接
if (tcp.Connected)
{

//获取网络流
NetworkStream networkStream = tcp.GetStream();
//将网络流作为二进制读写对象
br = new BinaryReader(networkStream);
bw = new BinaryWriter(networkStream);

bw.Write(str);//发送字符串命令
string result = br.ReadString();
if (result == "OK")
{
MessageBox.Show("取消成功！");
}
else
{
MessageBox.Show("取消失败！");
}

}

else
{
MessageBox.Show("无法连接服务器！");
return;
}
}
catch
{

MessageBox.Show("无法连接服务器！");
return;
