如何让一台机器在C＃中的IP地址 [英] How to get the IP address of a machine in C#

问题描述

我如何得到一台机器的IP地址，在C＃？

解决方案

  ip地址[] localIPs = Dns.GetHostAddresses（Dns.GetHostName（））;
 

您的设备没有一个单一的IP地址，以及一些返回的地址可以是IPv6的

MSDN链接：

• <一个href="http://msdn.microsoft.com/en-us/library/system.net.dns.gethostaddresses%28lightweight%29.aspx">Dns.GetHostAddresses
• <一个href="http://msdn.microsoft.com/en-us/library/system.net.ipaddress%28lightweight%29.aspx">IPAddress

另外，如 MSalters 的提及， 127.0.0.1 / :: 1 的环回地址，然后将总是指本地计算机。由于明显的原因，但是，它不能被用于从一个远程设备连接到本地计算机。

How do I get the IP address of a machine in C#?

解决方案

IPAddress[] localIPs = Dns.GetHostAddresses(Dns.GetHostName());

Your machine doesn't have a single IP address, and some of the returned addresses can be IPv6.

MSDN links:

• Dns.GetHostAddresses
• IPAddress

Alternatively, as MSalters mentioned, 127.0.0.1 / ::1 is the loopback address and will always refer to the local machine. For obvious reasons, however, it cannot be used to connect to the local machine from a remote machine.
