The following example displays endpoint information for active TCP connections.
public static void GetTcpConnections()
{
IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
// TcpConnectionInformation connections = properties.GetActiveTcpConnections();
TcpConnectionInformation[] connections = properties.GetActiveTcpConnections();
foreach (TcpConnectionInformation t in connections)
{
Console.Write("Local endpoint: {0} ",t.LocalEndPoint.Address);
Console.Write("Remote endpoint: {0} ",t.RemoteEndPoint.Address);
Console.WriteLine("{0}",t.State);
}
Console.WriteLine();
}
