ConsoleModifiers Enumeration
Represents the SHIFT, ALT, and CTRL modifier keys on a keyboard.
This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.
Namespace: SystemAssembly: mscorlib (in mscorlib.dll)
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) Do 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+") Console.WriteLine(cki.Key.ToString) Loop While cki.Key <> ConsoleKey.Escape End Sub End Class ' This example displays output similar to the following: ' Press any combination of CTL, ALT, and SHIFT, and a console key. ' Press the Escape (Esc) key to quit: ' ' a --- You pressed A ' k --- You pressed ALT+K ' ► --- You pressed CTL+P ' --- You pressed RightArrow ' R --- You pressed SHIFT+R ' --- You pressed CTL+I ' j --- You pressed ALT+J ' O --- You pressed SHIFT+O ' § --- You pressed CTL+U
