Question

我在我的应用程序中在运行时添加了一个可移动的PictureBox控件，如下面的代码所示。我希望当我双击运行时添加的PictureBox控件时，会打开一个新窗口。我试图添加双击事件，但它不起作用。你可以指导我如何在运行时双击添加的PictureBox控件时打开一个新窗口吗？

PictureBox[] PicArray;
PictureBox pb = new PictureBox();

pb.BackgroundImage = Image.FromFile(@"C:\Esp_Calculator\ESP Planner\1206570458690641104johnny_automatic_bridge.svg.med.png");
pb.Location = new Point(0, 0);
pb.BackColor = Color.Transparent;
pb.BackgroundImageLayout = ImageLayout.Zoom;

pb.MouseDown += new MouseEventHandler(this.drawArea_MouseDown);
pb.MouseMove += new MouseEventHandler(this.drawArea_MouseMove);
pb.MouseDoubleClick += pb_MouseDoubleClick;

drawArea.Controls.Add(pb);

List<PictureBox> lblList = new List<PictureBox>();

foreach (Control d in Controls)
    if (d is PictureBox)
        lblList.Add((PictureBox)d);

        PicArray = lblList.ToArray();

private void drawArea_MouseDown(object sender, MouseEventArgs e)
{
  move = e.Location;
}

private void drawArea_MouseMove(object sender, MouseEventArgs e)
{
    Control Pb = (Control)sender;
    if ((Control.ModifierKeys & Keys.Control) != 0)
    {
        if ((Control.MouseButtons & MouseButtons.Left) != 0)
        {
            Pb.Left += e.X - move.X;
            Pb.Top += e.Y - move.Y;
        }
    }
 }

void pb_MouseDoubleClick(object sender, System.Windows.Forms.MouseEventArgs e)
{
    Editor ed = new Editor();
    ed.Show();  
}

我明白了。 DoubleClick可以完成这项工作，而不是使用MouseDoubleClick事件。谢谢。以下是答案和工作代码：

     PictureBox[] PicArray;
PictureBox pb = new PictureBox();

        pb.BackgroundImage = Image.FromFile(@"C:\Esp_Calculator\ESP Planner\1206570458690641104johnny_automatic_bridge.svg.med.png");
        pb.Location = new Point(0, 0);
        pb.BackColor = Color.Transparent;
        pb.BackgroundImageLayout = ImageLayout.Zoom;





        pb.MouseDown += new MouseEventHandler(this.drawArea_MouseDown);
        pb.MouseMove += new MouseEventHandler(this.drawArea_MouseMove);
        pb.DoubleClick += pb_DoubleClick;

        drawArea.Controls.Add(pb);

        List<PictureBox> lblList = new List<PictureBox>();
        foreach (Control d in Controls)
            if (d is PictureBox)
                lblList.Add((PictureBox)d);
        PicArray = lblList.ToArray();

      private void drawArea_MouseDown(object sender, MouseEventArgs e)
      {
       move = e.Location;
       }
     private void drawArea_MouseMove(object sender, MouseEventArgs e)
     {
    Control Pb = (Control)sender;
    if ((Control.ModifierKeys & Keys.Control) != 0)
    {

        if ((Control.MouseButtons & MouseButtons.Left) != 0)
        {
            Pb.Left += e.X - move.X;
            Pb.Top += e.Y - move.Y;


        }
    }
 }

 void pb_DoubleClick(object sender, System.EventArgs e)
    {
        Editor ed = new Editor();
        ed.Show();
    }

如何打开一个新窗口，双击运行时添加的控件C＃？
