Question

I received a string over TCP socket. And this string looks something like this:

str = "10.100.200.200\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0";

How should I parse this into an IPAddress? If I do this,

IPAddress.TryParse(msg.nonTargetIP.Trim(), out ip);

it fails to parse.

What is simplest way to remove those trailing null’s?

Answer 1

IPAddress.TryParse(msg.nonTargetIp.Replace("\0", String.Empty).Trim(), out ip);

Alternatively reading up on Trim() you could do the following which is probably quicker:

IPAddress.TryParse(msg.nonTargetIp.TrimEnd(new char[] { '\0' } ), out ip);
