Public Enumeration ConsoleModifiers

Member nameDescription

The left or right ALT modifier key.


The left or right CTRL modifier key.


The left or right SHIFT modifier key.

No distinction is made between the left or right SHIFT, ALT, and CTRL keys.

The ConsoleModifiers enumeration is used in conjunction with the ConsoleKeyInfo type.

The following code example reads a key and determines whether one or more modifier keys was pressed.

Class Example
   Public Shared Sub Main()
      Dim cki As ConsoleKeyInfo
      ' Prevent example from ending if CTL+C is pressed.
      Console.TreatControlCAsInput = True

      Console.WriteLine("Press any combination of CTL, ALT, and SHIFT, and a console key.")
      Console.WriteLine("Press the Escape (Esc) key to quit: " + vbCrLf)
         cki = Console.ReadKey()
         Console.Write(" --- You pressed ")
         If (cki.Modifiers And ConsoleModifiers.Alt) <> 0 Then Console.Write("ALT+")
         If (cki.Modifiers And ConsoleModifiers.Shift) <> 0 Then Console.Write("SHIFT+")
         If (cki.Modifiers And ConsoleModifiers.Control) <> 0 Then Console.Write("CTL+")
      Loop While cki.Key <> ConsoleKey.Escape
   End Sub 
End Class
