C # methods to return all available drive symbols for the current system _python

The example in this article describes how C # returns all the available drive symbols for the current system. Share to everyone for your reference. as follows:

The initial C # code for the "plain" WMI query is generated by//WMI code generator, Version 5.00,//HTTP://WWW.ROBVA
