无法在C#中将域解析为IP? [英] Can't parse domain into IP in C#?

问题描述

我有此代码:

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

例如，当我在txtBoxIP(192.168.1.2)中有一个IP时，它会很好用.

When I have an IP in the txtBoxIP (192.168.1.2) for example, it works great.

但是，如果我想放置DNS?就像我放(my.selfip.com)一样，我得到了:

But if I want to put a DNS? like I'm putting (my.selfip.com) I get:

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

我如何使其同时支持IP和DNS?

How can I make it support both IP and DNS ?

推荐答案

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

别忘了错误处理.
