c# - 如何为 Windows Forms 窗体设置热键

Question

我想在我的 Windows 窗体表单中设置热键。例如，Ctrl + N 用于新建表单，Ctrl + S 用于保存。我该怎么做？

Answer 1

设置

myForm.KeyPreview = true;

为 KeyDown 创建处理程序 事件:

myForm.KeyDown += new KeyEventHandler(Form_KeyDown);

处理程序示例:

    // Hot keys handler
    void Form_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Control && e.KeyCode == Keys.S)       // Ctrl-S Save
        {
            // Do what you want here
            e.SuppressKeyPress = true;  // Stops other controls on the form receiving event.
        }
    }
