In this case we’re using the .Net Framework’s System.String class (that’s what the syntax[string]indicates). We then call the static method (indicated by the two colons, ::)Compare, passing the method three parameters: the two strings we want to compare ($a and $b) an...
The-matchand-cmatchoperators, which compare a string to a regular expression. PowerShell also contains many operators that reverse the logic of the comparison, such as-notlikeand-notin. You can make comparisons directly at the command prompt, which returns either True or Fa...
