Use ReadKey Method of Console Class in C#

Console.ReadKey(); is for the VS.NET Users. This makes the program wait for a key press and it prevents the screen from running and closing quickly when the program is launched from Visual Studio .NET.

A common use of the ReadKey() method is that you can halt the program execution. This could be done until a key is pressed by the user.

Let us see an example −

Example

 Live Demo

using System;

public class Demo {
   public static void Main() {
      DateTime date = DateTime.Now;
      TimeZoneInfo timeZone = TimeZoneInfo.Local;
      Console.WriteLine("Time Zone = {0}
", timeZone.IsDaylightSavingTime(date) ? timeZone.DaylightName : timeZone.StandardName);
      Console.Write(" to exit... ");
      while (Console.ReadKey().Key != ConsoleKey.Enter) {}
   }
}

Output

Time Zone = UTC
<Enter> to exit...
