We can use string.Split() get an array of all strings delimited by the parameter you pass it. For example:

var strings = mystring.Split('.');
// strings = {"aaa", "xxx", "b", "ccc", "12345"}

var str = strings[1];
// str = "xxx"

mystring.Split('.').Skip(1).FirstOrDefault();

We split at each '.' and we ignore the first then take the first one.

We need handling of nulls. if not just use First

You can you this:

string[] mystrings = mystring.Split('.');
string secondString = strings[1];
