foreach循环未检测到任何控件（图片框）

以下代码应该检测Controls属性中的所有图像框，并将碰撞应用到它。（这是CompSci最终项目的Windows形式）。问题在于它没有检测到任何图片框。否则，代码运行。有什么想法吗？

foreach (Control x in this.Controls)
            {
                if (x is PictureBox)
                {
                    if ((string)x.Tag == "platform")
                    {
                        if (PlayerPB.Bounds.IntersectsWith(x.Bounds))
                        {
                            force = 8;
                            PlayerPB.Top = x.Top - PlayerPB.Height;
                        }

                        x.BringToFront();
                    }
                }
            }

原文

This following code is supposed to detect all PictureBoxes in the Controls property, and apply collisions to it. (This is in Windows Form for a CompSci final project). The problem is that it is not detecting any PictureBoxes; otherwise, the code runs. Any ideas?

foreach (Control x in this.Controls)
            {
                if (x is PictureBox)
                {
                    if ((string)x.Tag == "platform")
                    {
                        if (PlayerPB.Bounds.IntersectsWith(x.Bounds))
                        {
                            force = 8;
                            PlayerPB.Top = x.Top - PlayerPB.Height;
                        }

                        x.BringToFront();
                    }
                }
            }

您需要在主要形式的每个容器中重复出现，并查看其中是否有任何图像框：

private void WirePBs(Control container) 
{
    foreach (Control x in container.Controls)
    {
        if (x is PictureBox) && (string)x.Tag == "platform")
        {
            if (PlayerPB.Bounds.IntersectsWith(x.Bounds))
            {
                force = 8;
                PlayerPB.Top = x.Top - PlayerPB.Height;
            }
            x.BringToFront();
        }
        else if (x.HasChildren)
        {
             WirePBs(x);
        }
    }
}

然后，您可以通过以形式本身传递来调用它：

WirePBs(this);

You need to recurse into each container within the main form and see if there are any PictureBoxes within there:

private void WirePBs(Control container) 
{
    foreach (Control x in container.Controls)
    {
        if (x is PictureBox) && (string)x.Tag == "platform")
        {
            if (PlayerPB.Bounds.IntersectsWith(x.Bounds))
            {
                force = 8;
                PlayerPB.Top = x.Top - PlayerPB.Height;
            }
            x.BringToFront();
        }
        else if (x.HasChildren)
        {
             WirePBs(x);
        }
    }
}

Then you can call it by passing in the form itself:
