C#适时监听IP端口

适时监听IP端口,,你起用一个新的线程让它悄芹唤循环就可以了,但是同一IP不能启凯连接2次.

Thread thread1 = new Thread(new ThreadStart(accp1))

thread1.IsBackground = true

thread1.Start()

private void accp1()

{

sfdu = 0

ggg:

accsock1 = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)

myserver1 = new IPEndPoint(myIP, sdkgh)//初始化主机对向（ip和断口）

sock1 = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)//初始化Socket使用方法不变

sock1.Bind(myserver1)//绑定主机(myserver)是以初始化的首昌主机

sock1.Listen(50)//监听的端口

int t = 1

while (t == 1)

{

try

{

accsock1 = sock1.Accept()//接受客户端的连接请求

if (accsock1.Connected)

{

//this.textBox3.AppendText("与客户端1500建立连接！")

Thread thread1 = new Thread(new ThreadStart(round1))

thread1.IsBackground = true

thread1.Start()

}

}

catch (ObjectDisposedException eee)

{

t = 2

goto ggg

}

catch (SocketException eeee)

{

t = 2

goto ggg

}

}

}

端口监听应该用改余橡的是UDP协议吧，获得源地址IP正常只能说明你已经可以和源地址通信，源端口号不是自己获得的，而是指定的，例：

你自己的地址是192.168.0.2 端口：1001

源地址的地址是192.168.0.3 端口：5656

那么，你的Winsock1.Protocol = sckUDPProtocol设置未UDP协议

然后设置毁皮端口Winsock1.LocalPort = 1001

接着Winsock1.RemotePort = 5656

Winsock1.RemoteHost =“192.168.0.3”

绑定本地端口Winsock1.Bind “192.168.0.2”

这样就监听成功了，核旁程序我没有测试，你先按照自己的本地配置修改试试看
