Gets an integer value that represents the key that is pressed or released (depending on which event is raised). This value is the nonportable key code, which is operating system–specific.
Assembly: System.Windows (in System.Windows.dll)
The portable key codes are a common subset of all the possible key codes of the supported operating systems. For example, the keystroke 'v' is represented as a Key value (which would evaluate as 51 if you cast it to an integer, but is more useful if you retain the enumeration information). That key would have a value of 86. Certain keystrokes, however, are not portable, such as the SCROLL LOCK key for Microsoft Windows. In this case, the Key value is Unknown, which is the value for any nonportable key, and the PlatformKeyCode is 145 on a Windows platform. For information about Microsoft Windows-specific key codes, see "Virtual-Key Codes" in the MSDN Library.
