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:  System
Assembly:  mscorlib (in mscorlib.dll)
[SerializableAttribute]
[FlagsAttribute]
public enum ConsoleModifiers
Member nameDescription
AltThe left or right ALT modifier key.
ControlThe left or right CTRL modifier key.
ShiftThe 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.

using System;

class Example 
{
   public static void Main() 
   {
      ConsoleKeyInfo cki;
      // 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: \n");
      do 
      {
         cki = Console.ReadKey();
         Console.Write(" --- You pressed ");
         if((cki.Modifiers & ConsoleModifiers.Alt) != 0) Console.Write("ALT+");
         if((cki.Modifiers & ConsoleModifiers.Shift) != 0) Console.Write("SHIFT+");
         if((cki.Modifiers & ConsoleModifiers.Control) != 0) Console.Write("CTL+");
         Console.WriteLine(cki.Key.ToString());
       } while (cki.Key != ConsoleKey.Escape);
    }
}
// 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
