C# How to detect whether there is a '/' character?
===

I have three IP addresses from serial port in one string. For example the string is like `192.168.1.1/192.168.1.12/192.168.1.118`. How do we detect the '/' character so that we can split this string into 3 IP address string and put each one into IP1 string, IP2 string and IP3 string?
