반환

누른 콘솔 키에 해당하는 ConsoleKey 상수 및 유니코드 문자(있을 경우)를 설명하는 개체입니다.An object that describes the ConsoleKey constant and Unicode character, if any, that correspond to the pressed console key. ConsoleKeyInfo 개체는 하나 이상의 Shift, Alt 또는 Ctrl 보조키를 콘솔 키와 동시에 눌렀는지 여부를 나타내는 ConsoleModifiers 값을 비트 조합으로 나타냅니다.The ConsoleKeyInfo object also describes, in a bitwise combination of ConsoleModifiers values, whether one or more Shift, Alt, or Ctrl modifier keys was pressed simultaneously with the console key.

예외

In 속성이 콘솔 이외의 다른 스트림에서 리디렉션됩니다.The In property is redirected from some stream other than the console.

예제

ReadKey() 메서드의 가장 일반적인 사용 방법 중 하나는 사용자가 키를 누를 때까지 프로그램 실행을 중단 하 고 앱이 종료 되거나 추가 정보 창을 표시 하는 것입니다.One of the most common uses of the ReadKey() method is to halt program execution until the user presses a key and the app either terminates or displays an additional window of information. 다음 예제에서는 ReadKey() 메서드를 사용 하 여 앱을 종료 하기 전에 사용자가 Enter 키를 누를 때까지 기다립니다.The following example uses the ReadKey() method to wait for the user to press the Enter key before terminating the app.

using System;

public class Example
{
   public static void Main()
   {
      DateTime dat = DateTime.Now;
      Console.WriteLine("The time: {0:d} at {0:t}", dat);
      TimeZoneInfo tz = TimeZoneInfo.Local;
      Console.WriteLine("The time zone: {0}\n", 
                        tz.IsDaylightSavingTime(dat) ?
                           tz.DaylightName : tz.StandardName);
      Console.Write("Press <Enter> to exit... ");
      while (Console.ReadKey().Key != ConsoleKey.Enter) {}
   }
}
// The example displays output like the following:
//     The time: 11/11/2015 at 4:02 PM:
//     The time zone: Pacific Standard Time
Module Example
   Public Sub Main()
      Dim dat As Date = Date.Now
      Console.WriteLine("The time: {0:d} at {0:t}", dat)
      Dim tz As TimeZoneInfo = TimeZoneInfo.Local
      Console.WriteLine("The time zone: {0}", 
                        If(tz.IsDaylightSavingTime(dat),
                           tz.DaylightName, tz.StandardName))
      Console.WriteLine()
      Console.Write("Press <Enter> to exit... ")
      Do While Console.ReadKey().Key <> ConsoleKey.Enter
      Loop
   End Sub
End Module
' The example displays the following output:

ReadKey 메서드의이 오버 로드는 기본적으로 사용자가 콘솔로 누르는 모든 표시할 수 있는 키를 에코 합니다.Note that this overload of the ReadKey method by default echoes any displayable keys that the user presses to the console. 이를 표시 하지 않으려면 trueintercept 인수를 사용 하 여 ReadKey 메서드를 호출 합니다.To suppress them, call the ReadKey method with an intercept argument of true.

다음 예제에서는 ReadKey() 메서드를 사용 하 여 사용자가 누른 키에 대 한 정보를 표시 합니다.The following example uses the ReadKey() method to display information about which key the user 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());

ReadKey 메서드는 문자 또는 함수 키를 누를 때까지 ReadKey 메서드를 실행 하는 스레드에 대 한 블록을 대기 합니다.The ReadKey method waits, that is, blocks on the thread issuing the ReadKey method, until a character or function key is pressed. 하나 이상의 Alt, Ctrl 또는 Shift 보조키를 사용 하 여 조합에서 문자 또는 함수 키를 누를 수입니다.A character or function key can be pressed in combination with one or more Alt, Ctrl, or Shift modifier keys. 그러나 한정자 키를 단독으로 누르면 ReadKey 메서드가 반환 되지 않습니다.However, pressing a modifier key by itself will not cause the ReadKey method to return.

애플리케이션에 따라 사용 하려는 합니다 ReadKey 와 함께에서 메서드는 KeyAvailable 속성입니다.Depending on your application, you might want to use the ReadKey method in conjunction with the KeyAvailable property.

ReadKey 메서드는 표준 입력이 SetIn 메서드를 사용 하 여 파일로 리디렉션되는 경우에도 키보드에서 읽습니다.The ReadKey method reads from the keyboard even if the standard input is redirected to a file with the SetIn method.
