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

If the port number is always provided after a ':', the following method may be a more elegant option (in code length instead of efficiency).

public static IPEndpoint ParseIPEndpoint(string ipEndPoint) {
    int ipAddressLength = ipEndPoint.LastIndexOf(':');
    return new IPEndPoint(
        IPAddress.Parse(ipEndPoint.Substring(0, ipAddressLength)),
        Convert.ToInt32(ipEndPoint.Substring(ipAddressLength + 1)));
}

It works fine for my simple application without considering complex IP address format.
