使用TcpListener获取一个可用的端口
public static int GetRandomPort()
{
var listener = new TcpListener(IPAddress.Any, 0);
listener.Start();
var port = ((IPEndPoint)listener.LocalEndpoint).Port;
listener.Stop();
return port;
}
获取所有被绑定的端口
public static IList PortIsUsed()
{
//获取本地计算机的网络连接和通信统计数据的信息
IPGlobalProperties ipGlobalProperties = IPGlobalProperties.GetIPGlobalProperties();
//返回本地计算机上的所有Tcp监听程序
IPEndPoint[] ipsTCP = ipGlobalProperties.GetActiveTcpListeners();
//返回本地计算机上的所有UDP监听程序
IPEndPoint[] ipsUDP = ipGlobalProperties.GetActiveUdpListeners();
//返回本地计算机上的Internet协议版本4(IPV4 传输控制协议(TCP)连接的信息。
TcpConnectionInformation[] tcpConnInfoArray = ipGlobalProperties.GetActiveTcpConnections();
IList allPorts = new ArrayList();
foreach (IPEndPoint ep in ipsTCP)
{
allPorts.Add(ep.Port);
}
foreach (IPEndPoint ep in ipsUDP)
{
allPorts.Add(ep.Port);
}
foreach (TcpConnectionInformation conn in tcpConnInfoArray)
{
allPorts.Add(conn.LocalEndPoint.Port);
}
return allPorts;
}
