推荐答案

KeyDown 事件，如此处所述
http://msdn.microsoft.com/en-us/library/system.windows.forms.control.keydown.aspx [ ^ ]
可用于此目的.
要在传递给表单上的任何控件之前捕获按下的键，
可以将KeyPreview 的KeyPreview 属性设置为True，这表示在将事件传递给具有焦点的控件之前，窗体将接收键事件，如此处所述
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.keypreview.aspx [ ^ ]

The KeyDown event as explained here
http://msdn.microsoft.com/en-us/library/system.windows.forms.control.keydown.aspx[^]
can be used for this purpose.
To capture the key pressed before it is passed on to any control on the form,
KeyPreview property of Form can be set to True, which indicates that the form will receive key events before the event is passed to the control that has focus as explained here
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.keypreview.aspx[^]

嘿，

试试这个

hey,

try this

protected override bool ProcessCmdKey(ref Message msg, Keys keyData) {
        if (keyData == Keys.Left) {
            Console.WriteLine("left");
            return true;
        }
        // etc..
        return base.ProcessCmdKey(ref msg, keyData);
    }

祝你好运
