Best way to create IPEndpoint from string

Question

Since IPEndpoint contains a ToString() method that outputs:

10.10.10.10:1010

There should also be

Answer 1

This will do IPv4 and IPv6. An extension method for this functionality would be on System.string. Not sure I want this option for every string I have in the project.

private static IPEndPoint IPEndPointParse(string endpointstring)
{
    string[] values = endpointstring.Split(new char[] {':'});

    if (2 > values.Length)
    {
        throw new FormatException("Invalid endpoint format");
    }

    IPAddress ipaddress;
    string ipaddressstring = string.Join(":", values.Take(values.Length - 1).ToArray());
    if (!IPAddress.TryParse(ipaddressstring, out ipaddress))
    {
        throw new FormatException(string.Format("Invalid endpoint ipaddress '{0}'", ipaddressstring));
    }

    int port;
    if (!int.TryParse(values[values.Length - 1], out port)
     || port < IPEndPoint.MinPort
     || port > IPEndPoint.MaxPort)
    {
        throw new FormatException(string.Format("Invalid end point port '{0}'", values[values.Length - 1]));
    }

    return new IPEndPoint(ipaddress, port);
}
