推荐答案

您确定已将Num Lock保持打开状态以启用数字键盘输入吗?

还是我想念什么?请详细阐述问题以获得更合适的答案.

Are you sure you''ve kept Num Lock ON for enabling Number pad inputs?

or I am missing something ? please elaborate question in detail for getting more suitable answers.

我认为您甚至可能在KeyDown中使用了KeyCode，例如

I think you might have used KeyCode in KeyDown even, like

e.KeyCode = Windows.Forms.Keys.D2

其中D2与NumPad2不同.

尝试在KeyPress事件中使用KeyChar.

共享一些代码(如果这样做无济于事).

where D2 is different from NumPad2.

Try using KeyChar in KeyPress event.

Share some code if this doesn''t help.

您要做的就是敲击键盘上的NumLock键(指示灯应该亮起.)就这样，您的代码根本不需要执行任何操作.

All you do is hit the NumLock key on your keyboard (the light should turn on.) That''s it, nothing needs to be done in your code at all.
