推荐答案

您可以创建一个控制台应用程序的全局键盘钩子了。

You can create a global keyboard hook in a console application, too.

下面是完整的，工作code：

您创建的控制台应用程序的，但必须在引用的 System.Windows.Forms的添加的这个工作。没有理由一个控制台应用程序不能引用的DLL。

主线程将运行Application.Run（），直到退出应用程序，例如通过以Application.Exit（）的调用。做其他的工作，最简单的方法是开始一个新的任务来完成这项工作。下面是从链接code，这是否主要（）的修改版

The main thread will run Application.Run() until the application exits, e.g. via a call to Application.Exit(). The simplest way to do other work is to start a new Task to perform that work. Here's a modified version of Main() from the linked code that does this

public static void Main()
{
    var doWork = Task.Run(() =>
        {
            for (int i = 0; i < 20; i++)
            {
                Console.WriteLine(i);
                Thread.Sleep(1000);
            }
            Application.Exit(); // Quick exit for demonstration only.  
        });

    _hookID = SetHook(_proc);

    Application.Run();

    UnhookWindowsHookEx(_hookID);
}

可能提供退出控制台应用程序例如一种手段当一个特殊的组合键是$ P $根据您的具体需求pssed。在
