Question

如果在表单中我有10个面板按1到10的顺序命名，并且所有面板都注册了相同的事件myPanel_Click

private void myPanel_Click(object sender, EventArgs e)
{

}

我可以检索我在这10个面板中点击的面板的名称吗？

int panelClicked;
private void myPanel_Click(object sender, EventArgs e)
{
    //not a single clue
}

Answer 1

如果我理解正确，您应该能够将发件人转换为面板，然后取名称属性。

private void myPanel_Click(object sender, EventArgs e)
{
    Panel target = sender as Panel;
    if(target != null)
        MessageBox.Show(target.Name);
}

Answer 2

private void myPanel_Click(object sender, EventArgs e)
{
    MessageBox.Show((Panel)sender.Name);
}

Answer 3

您也可以Tag Property来引用您的面板，方法是将您的面板编号分配给相应的标签。

private void myPanel_Click(object sender, EventArgs e)
{
   Panel p = (Panel)sender;
   switch ((int)p.Tag )
   {
       case 1:
           // Your Code for Panel 1
           break;
       case 2:
           // Your Code for Panel 2 
           break;
       // Your other Panels here
       default:
           break;
   }
}
