Windows窗体：图片框手动拖动图片解决方案的操作？

Question

您好我写这将dragginging图片框在WinForm的代码，这是我的代码：

private void pictureBox1_MouseUp(object sender, MouseEventArgs e) 
    { 

     pictureBox1.Top=(56 * ((pictureBox1.Top + (e.Y - firsty))/56) + 3); //this for the correction of location of picture box 
     isdragging[0] = false; 

    } 
    private void pictureBox1_MouseDown(object sender, MouseEventArgs e) 
    { 
     isdragging[0] = true; 
     firstx = e.X; 
     firsty = e.Y; 
     changeclickingstatus(pictureBox1);//this about my program 
     for (sbyte i = 0; i < (sbyte)20; i++)//this about my program 
     { 
      clickindex[i] = (sbyte)1;//this about my program 
     } 
     clickindex[0] = (sbyte)0;//this about my program 
     dragtop = (sbyte)(pictureBox1.Top/56);//this about my program 
     } 



     private void pictureBox1_MouseMove(object sender, MouseEventArgs e) 
     { 
     if (isdragging[0]) 
     { 

      if (pictureBox1.Location.Y + (e.Y - firsty) < 0) 
      { 
       pictureBox1.Top = 0;//these are the limits of dragging 

      } 
      else if (pictureBox1.Location.Y + (e.Y - firsty) > 290) 
      { 
       pictureBox1.Top = 290;//these are the limits of dragging 

      } 
      else 
      { 



       pictureBox1.Top = pictureBox1.Top + (e.Y - firsty); 

      } 


      if (pictureBox1.Location.X + (e.X - firstx) < 6) 
      { 
       pictureBox1.Left = 6;//these are the limits of dragging 
      } 
      else if (pictureBox1.Location.X + (e.X - firstx) > 280) 
      { 
       pictureBox1.Left = 280;//these are the limits of dragging 
      } 
      else 
      { 
       pictureBox1.Left = pictureBox1.Left + (e.X - firstx); 

      } 

     } 
    } 

和我有相同的代码PictureBox的2，我的问题是： 当我拖着我的第一张照片第二个它会覆盖它并且代码正常工作，但是当我将第二个图片框拖动到第一个图片框时，第二个图片框会在第一个图片框下拖动！有没有这方面的财产？

您可以使用BringToFront()方法：

private void pictureBox1_MouseDown(object sender, MouseEventArgs e) 
{ 
    pictureBox1.BringToFront(); 
    /**/ 
} 

private void pictureBox2_MouseDown(object sender, MouseEventArgs e) 
{ 
    pictureBox2.BringToFront(); 
    /**/ 
}
