First, use IndexOf[^] to locate the position of the ?? in the string, then use Substring[^] to extract the part that you want.

You can use, for example, regular expressions:

You can do the same by some combination of System.String members, for example, Length, IndexOf(String) and Substring(Int32), another way would be using Split(Char[], StringSplitOptions) or Split(String[], StringSplitOptions) with System.StringSplitOptions.RemoveEmptyEntries:
