如何在C#控制台应用程序中捕获修改器(ctrl,alt,shift)按键作为单键按下？

概述Console.ReadKey仅在按下“普通”键时捕获输入,然后将修饰符(如果有)作为键信息的一部分附加.如何将单个修改键按下作为输入？ 在 this link中提供了一个解决方案.我对上述代码进行了一些编辑,以作为您问题的答案. 要运行此代码： >创建控制台应用程序 >添加对System.Windows.Forms.dll程序集的引用 >粘贴此代码并进行测试. 码： using System; Console.ReadKey仅在按下“普通”键时捕获输入,然后将修饰符(如果有)作为键信息的一部分附加.如何将单个修改键按下作为输入？解决方法 在 this link中提供了一个解决方案.我对上述代码进行了一些编辑,以作为您问题的答案.
