using System;
using System.Collections.Generic;
using System.Net;

namespace GetMachineIP
{
class Program
{
static List<string> GetIPByHostName(string strHostName)
{

// Then using host name, get the IP address list..
IPHostEntry ipEntry = Dns.GetHostByName(strHostName);
IPAddress[] addr = ipEntry.AddressList;
List<string> ips = new List<string>();

for (int i = 0; i < addr.Length; i++)
{
ips.Add(addr[i].ToString());
}
return ips;
}

public static int Main(string[] args)
{

String strHostName = "";
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];
}

var ips = GetIPByHostName(strHostName);

foreach (var ip in ips)
{
Console.WriteLine(ip);
}

return 0;
}
}
}追问是局域网内，通过电脑名或者其他固定的条件方式获取其他电脑对应的IP

static System.Net.Dns.Resolve(电脑名).AddressList

IPHostEntry hostEntry;

hostEntry= Dns.GetHostEntry(host);
if (hostEntry.AddressList.Length > 0)
{ var ip = hostEntry.AddressList[0];

}
