Get IP address in a console application
提问by
I am looking to figure out what my IP address is from a console application.
我想从控制台应用程序中找出我的 IP 地址。
I am used to a web application by using the Request.ServerVariablescollection and/or Request.UserHostAddress.
我习惯于使用Request.ServerVariables集合和/或Request.UserHostAddress.
How can this be done in a console app?
这如何在控制台应用程序中完成？

The easiest way to do this is as follows:
最简单的方法如下：
using System;
using System.Net;
namespace ConsoleTest
{
class Program
{
static void Main()
{
String strHostName = string.Empty;
// Getting Ip address of local machine...
// First get the host name of local machine.
strHostName = Dns.GetHostName();
Console.WriteLine("Local Machine's Host Name: " + strHostName);
// Then using host name, get the IP address list..
IPHostEntry ipEntry = Dns.GetHostEntry(strHostName);
IPAddress[] addr = ipEntry.AddressList;
for (int i = 0; i < addr.Length; i++)
{
Console.WriteLine("IP Address {0}: {1} ", i, addr[i].ToString());
}
Console.ReadLine();
}
}
}

using System;
using System.Net;
public class DNSUtility
{
public static int Main (string [] args)
{
String strHostName = new String ("");
if (args.Length == 0)
{
// Getting Ip address of local machine...
// First get the host name of local machine.
strHostName = DNS.GetHostName ();
Console.WriteLine ("Local Machine's Host Name: " + strHostName);
}
else
{
strHostName = args[0];
}
// Then using host name, get the IP address list..
IPHostEntry ipEntry = DNS.GetHostByName (strHostName);
IPAddress [] addr = ipEntry.AddressList;
for (int i = 0; i < addr.Length; i++)
{
Console.WriteLine ("IP Address {0}: {1} ", i, addr[i].ToString ());
}
return 0;
}
}

System.Net.Dns.GetHostAddresses() should do it.
System.Net.Dns.GetHostAddresses() 应该这样做。

The System.Net namespace is your friend here. In particular, APIs such as DNS.GetHostByName.
System.Net 命名空间是您的朋友。特别是诸如 DNS.GetHostByName 之类的 API。
However, any given machine may have multiple IP addresses (multiple NICs, IPv4 and IPv6 etc) so it's not quite as simple a question as you pose.
但是，任何给定的机器都可能有多个 IP 地址（多个 NIC、IPv4 和 IPv6 等），因此问题并不像您提出的那么简单。

Try this:
尝试这个：
String strHostName = Dns.GetHostName();
Console.WriteLine("Host Name: " + strHostName);
// Find host by name IPHostEntry
iphostentry = Dns.GetHostByName(strHostName);
// Enumerate IP addresses
int nIP = 0;
foreach(IPAddress ipaddress in iphostentry.AddressList) {
Console.WriteLine("IP #" + ++nIP + ": " + ipaddress.ToString());
}

IPAddress[] addresslist = Dns.GetHostAddresses(Dns.GetHostName());
IPAddress[] 地址列表 = Dns.GetHostAddresses(Dns.GetHostName());
