无法在C#中将域解析为IP？

Question

我有这个代码:

IPEndPoint serverEndPoint = new IPEndPoint(IPAddress.Parse(txtBoxIP.Text), MainForm.port);

例如,当我在txtBoxIP(192.168.1.2)中有IP时,效果很好.

但是,如果我想放一个DNS？就像我放(my.selfip.com)我得到的:

System.FormatException: An invalid IP address was specified.
at System.Net.IPAddress.InternalParse(String ipString, Boolean tryParse)

如何使其支持IP和DNS？

Answer 1

IPAddress ipAddress;
if (!IPAddress.TryParse (txtBoxIP.Text, out ipAddress))
   ipAddress = Dns.GetHostEntry (txtBoxIP.Text).AddressList[0];
serverEndPoint = new IPEndPoint(ipAddress, MainForm.port)

不要忘记错误处理.
