方法描述
指定控制台上的标准键。
语法定义(C# System.ConsoleKey 枚举 的用法)
[SerializableAttribute] public enum ConsoleKey
提示和注释
ConsoleKey 枚举通常用在 System.ConsoleKeyInfo 结构中，Console.ReadKey 方法返回此结构以指示控制台上被按下的键。
System.ConsoleKey 枚举例子
下面的示例使用 ConsoleKey 枚举向用户指示该用户按下了哪个键。
using System;
using System.Text;
public class ConsoleKeyExample
{
public static 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 = new 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.
//
