例

次の例では、列挙体を使用して、 ConsoleKey ユーザーが押されたキーをユーザーに示します。The following example uses the ConsoleKey enumeration to indicate to the user which key the user had pressed.

using namespace System;
using namespace System::Text;

void main()
{
   ConsoleKeyInfo input;
   do {
      Console::WriteLine("Press a key, together with Alt, Ctrl, or Shift.");
      Console::WriteLine("Press Esc to exit.");
      input = Console::ReadKey(true);

      StringBuilder^ output = gcnew StringBuilder(
                     String::Format("You pressed {0}", input.Key.ToString()));
      bool modifiers = false;

      if ((input.Modifiers & ConsoleModifiers::Alt) == ConsoleModifiers::Alt) {
         output->Append(", together with " + ConsoleModifiers::Alt.ToString());
         modifiers = true;
      }
      if ((input.Modifiers & ConsoleModifiers::Control) == ConsoleModifiers::Control)
      {
         if (modifiers) {
            output->Append(" and ");
         }   
         else {
            output->Append(", together with ");
            modifiers = true;
         }
         output->Append(ConsoleModifiers::Control.ToString());
      }
      if ((input.Modifiers & ConsoleModifiers::Shift) == ConsoleModifiers::Shift)
      {
         if (modifiers) {
            output->Append(" and ");
         }   
         else {
            output->Append(", together with ");
            modifiers = true;
         }
         output->Append(ConsoleModifiers::Shift.ToString());
      }
      output->Append(".");                  
      Console::WriteLine(output->ToString());
      Console::WriteLine();
   } while (input.Key != ConsoleKey::Escape);
}
// The output from a sample console session might appear as follows:
//       Press a key, along with Alt, Ctrl, or Shift.
//       Press Esc to exit.
//       You pressed D.

//

注釈

列挙体は、 ConsoleKey 通常、.nfo 構造体で使用されます。これは、 Console.ReadKey コンソール上のどのキーが押されたかを示すためにメソッドによって返されます。The ConsoleKey enumeration is typically used in the nfo structure, which is returned by the Console.ReadKey method to indicate which key on the console has been pressed.
