代码如下:

	

	public static IPAddress GetHostIP()

	{

	            IPHostEntry ipe = Dns.GetHostEntry(Dns.GetHostName());

	            IPAddress ip = ipe.AddressList[0];
	

		 
	

		            return ip;

		}
	

		private String GetIPAddress()

		{

		            String str;

		            String Result = "";

		            String hostName = Dns.GetHostName();

		            IPAddress[] myIP = Dns.GetHostAddresses(hostName);

		            foreach (IPAddress address in myIP)

		            {

		                str = address.ToString();

		                for (int i = 0; i < str.Length; i++)

		                {

		                    if (str[i] >= '0' && str[i] <= '9' || str[i] == '.') Result = str;

		                }

		            }

		            return Result;

		}
