Examples
The following code example reads a key and determines whether one or more modifier keys was pressed.
using namespace System;
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) != ConsoleModifiers()) Console::Write("ALT+");
if((cki.Modifiers & ConsoleModifiers::Shift) != ConsoleModifiers()) Console::Write("SHIFT+");
if((cki.Modifiers & ConsoleModifiers::Control) != ConsoleModifiers()) 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 }
