在C#中添加F5热键 [英] Adding an F5 Hotkey in C#

问题描述

我正在制作一个Windows应用程序(WinForms)，并希望我的应用程序在用户按下F5时调用一个方法-无论用户在做什么，它都可以工作，但是他们必须使用该程序-我不想使用全局挂钩-有什么想法吗?

I'm making a windows app (WinForms) and would like my application to call a method when the user presses F5 - this should work no matter what the user is doing but they must be using the program - I don't want to use global hooks - any ideas?

推荐答案

覆盖表单的

Override the form's ProcessCmdKey on your main form and look for F5.

protected override bool ProcessCmdKey (ref Message msg, Keys keyData)
{
    bool bHandled = false;
    // switch case is the easy way, a hash or map would be better, 
    // but more work to get set up.
    switch (keyData)
    {
        case Keys.F5:
            // do whatever
            bHandled = true;
            break;
    }
    return bHandled;
}
