Get IP address through c# (in IPv4 value)

Programming in C#: Get IP address through c# (in IPv4 value) on newest questions tagged c# – Stack Overflow

I try the following code to get my IP address, in XP, it returns the IP address V4 format,
but when I do it in my system(windows 7), it return the ip address in v6 format.

How do to solve this?

Code

try
{
      //iphostname = Dns.GetHostName();  // Resolving Host name
      IPHostEntry ipentry = Dns.GetHostEntry(hostLabel.Text);
      IPAddress[] addr = ipentry.AddressList;// Resolving IP Addresses
      for (int i = 0; i < addr.Length; i++)
      {
           try
           {
               ipLabel.Text = Convert.ToString(addr[i]) + "\r\n";
           }
           catch
           {
               ipLabel.Text += "IP Address            | " + "\r\n";
           }
      }
}
catch
{
     //richTextBox1.Text += "Hostname             | " + "\r\n";
}
