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.
Assembly: mscorlib (in mscorlib.dll)
| Member name | Description | |
|---|---|---|
| Alt | The left or right ALT modifier key. | |
| Control | The left or right CTRL modifier key. | |
| Shift | 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.
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
