Question

在我的previus帖子中，我问如何创建一组n个可拖动的按钮，这些按钮工作正常，但我现在正在研究以下内容：

我在图像上放置了一个图像，并加载了一个坐标矩阵，这样当我也拖动图像时，按钮“跟随图像”，我试图通过在按钮完成时调用一个事件来完成它被拖动，调用事件并将“图像坐标”转换为“形状坐标”。它只适用于一个，但是当我放置n个按钮时出现问题，因为我不知道如何“识别”哪个按钮称为事件，我将告诉你我是如何做到的：

 int x, y;

 //Creates a set of four buttons with an icon
 for (int i = 0; i < 4; i++)
 {
     x = rnd.Next(1, this.Width - 30);
     y = rnd.Next(1, this.Height - 30);
     botonCustom newboton = new botonCustom(32, 32, new Point(x, y), imageList1);

     //New event for each button (Is it ok to do?)
     //I tried to call the same function newboton_Move, since i do not know how to create an event for each button
     newboton.Move += new EventHandler(newboton_Move);

     //Name the button and writes it on a lablel
     newboton.Description = EtiDiamond[i];
     DiamondButton.Add(newboton);
     this.Controls.Add(newboton);
  }

这是被调用的函数：

private void newboton_Move(object sender, EventArgs e)
{
   // Here i use the coordinates transform method, i won't place the code because
   // its too big and it goes against the rules :P, i think if i could somehow know which button called this...         
}

sender是引发事件的按钮

var myButton = sender as Button;

在表单上调用n个按钮的事件
