在C#控制台应用程序中使用Keyboard.IsKeyDown [英] Use Keyboard.IsKeyDown in C# console application

问题描述

我正在编写一个控制台应用程序，在控制台屏幕上显示某些数据，而不是检查键盘上的用户输入并最终根据需要进行处理.所有单线程.

I'm writing an console application witch Displaying certain data on the console screen, than checking for user input from the keyboard and finally handleing it by need. all single threaded.

为此，我尝试使用System.Windows.Input命名空间中的Keyboard.IsKeyDown方法.而Visual Studio则不允许这样做. 有谁知道为什么并且可以帮助我吗? 我看不到仅使用一个线程而不使用计时器来实现该逻辑的其他方法.

For that i tried using Keyboard.IsKeyDown Method from System.Windows.Input namespace. and visual studio wo'nt allow it. Does anyone knows why and can help me? I dont see other way implementing that logic using only one thread and no timer's.

推荐答案

使用

Use Console.ReadKey() to read input from the keyboard in a console application.

请注意，这是一个阻止呼叫.如果您不想阻止，请与Console.KeyAvailable结合使用.例如，该程序将循环并显示每10秒是否按下一个键:

Note that this is a blocking call. If you don't want to block, combine with Console.KeyAvailable. For example, this program will loop and display if a key is pressed every 10th of a second:

static void Main(string[] args)
{
    do
    {
        if (Console.KeyAvailable)
        {
            var key = Console.ReadKey();
            Console.WriteLine(key.Key);
        }
        else
        {
            Console.WriteLine("No key pressed");
        }
        System.Threading.Thread.Sleep(100);
    } while (true);
}
