In this post, we will see how to get the public IP Address of a computer using C#. Here’s the code snippet that does this:

static string GetIPAddress()
{
    String address = "";
    WebRequest request = WebRequest.Create("http://checkip.dyndns.org/");
    using (WebResponse response = request.GetResponse())
     using (StreamReader stream = new StreamReader(response.GetResponseStream()))
     {
        address = stream.ReadToEnd();
     }

     int first = address.IndexOf("Address: ") + 9;
     int last = address.LastIndexOf("</body>");
     address = address.Substring(first, last - first);

     return address;
}

In the above code snippet, we are making a request to the website that displays the IP address of the current computer. We are receiving the response and parsing the response to get the IP address.
