是否检测到在应用程序启动时按住Ctrl键? [英] Detecting Ctrl key being held down on application startup?

问题描述

当我们的WPF应用程序启动时，它使用Single Sign On登录.为了允许测试人员模拟其他用户，我们希望检测到启动时按住Control键，并弹出一个登录对话框.

When our WPF application starts, it uses Single Sign On to log in. To allow testers to simulate other users, we'd like to detect the Control button being held down on startup, and pop up a login dialog.

推荐答案

这是我在WPF应用程序中使用的功能，用于检查主窗口的构造函数中是否按住了控制键.它使用 System.Windows.Input.Keyboard

This is what I use in a WPF app to check if the control key is being held down in the constructor of the main Window. It uses System.Windows.Input.Keyboard

if ((Keyboard.Modifiers & ModifierKeys.Control) > 0)
    PromptForMarketSelection();
