C#，对吗?代码卡在一个地方? [英] C#, huh? Code Stuck In One Place?

问题描述

我有此代码

I have this code

private void Form2_Keydown(object sender, KeyEventArgs e)
  {
      if (e.KeyCode == Keys.Up)
      {
          You.Location = new Point(You.Location.X, You.Location.Y - 5);
      }
  }

(您=图片框)

而且我没有出现任何错误，它可以在Form1中很好地工作，但是当我尝试在Form2中使用它时，什么也没发生，我有点困惑，有人可以帮助我吗?

(You = Picturebox)

And I get no errors popping up on it,and it works in Form1 great but when I try to use it in Form2 Nothing happens and I''m a bit confused can anyone help me?

推荐答案

您确定表单上的"KeyPreview"属性设置为True吗?

Have you made sure the ''KeyPreview'' property on the form is set to True?

重复的问题！我已经回答:

按下事件的C#问题 [

Duplicate question! I already answered:

C# problem with keys down event[^].

I think you ignored second part of the Answer.

Please try and tell us what you get. You can also use advice about ProcessKeyCmd by Dylan, should work.

Sunasara是正确的:您是否忘记将KeyDown事件分配给处理程序?您可以在设计器模式下执行此操作，也可以直接在构造函数中执行此操作，例如:

Sunasara is right: didn''t you forget to assign the KeyDown event to your handler? You can do this in designer mode, or directly in the constructor for example:

public Form2()
{
    InitializeComponent();
    KeyDown += new KeyEventHandler(Form2_KeyDown);
}
