How to get local IP address of Windows system?

Question

Is there any code or method to get the IP addresses of the local system?

Answer 1

If you are in C#, you could use .NET:

using System;
using System.Net;

public static string GetLocalIP() {
  var hosts = Dns.GetHostEntry(Dns.GetHostName());
  foreach (var ipEntry in host.AddressList)
  {
    if (ipEntry.AddressFamily == AddressFamily.InterNetwork)
    {
      return ip.ToString();
    }
  }
}

You can later add a throw new Exception at the end, it will show up if you have no IPv4 adapters installed.
