推荐答案

参见屏幕截图 [ ^ ]

图像是一个显示在图片框中的图片，是全部 - 您添加到PictureBox.Controls集合的任何其他控件实际上根本没有在图像上绘制，它们是在屏幕上绘制的（或者使用的其他图形上下文）显示PictureBox）但不以任何方式，形状或形式改变Image属性。



如果你想修改图像，你必须得到一个图形上下文，并绘制到它。



但是......如果你想拍摄带有图像和控件的图片框的快照，请查看ethe Graphics.CopyFromScreen Method（System.Drawing）| Microsoft Docs [ ^ ] - 它应该让你这样做到一个新的位图，你可以随后做你喜欢的事。

An Image is a picture which is displayed in a Picture box, is all - any other controls you add to the PictureBox.Controls collection aren't actually drawn on the Image at all, they are drawn on the screen (or other Graphics context used to displaying the PictureBox) but do not in any way, shape, or form alter the Image property.

If you want to modify the Image, your have to get a graphics context for it, and draw onto that.

But ... if you want to take a "snapshot" of the picturebox complete with Image and controls on top of it, look at ethe Graphics.CopyFromScreen Method (System.Drawing) | Microsoft Docs[^] - it should let you do that onto a new bitmap, which you can do what you like with afterwards.

谢谢你。我找到了以下指南：

thank you. I found following guide:
