推荐答案

一次又一次地回答这个问题是无法忍受的;它经常被问到。请这样做：

http ：//www.codeproject.com/search.aspx？doctypeid = 5& q = SQL +％28images + OR + image％29 [ ^ ]。



现在，它看起来像是在 PictureBox 中修改图像。为什么，在地球上？你可以做到，但这完全没有意义。这个控件只不过是用来做一些非常简单的快捷方式：在屏幕上显示静态图像。如果你做任何更复杂的事情，你只需要做双重工作;而电脑也做双重工作。控制不是图像。



我会告诉你该怎么做。您应该直接在控件中渲染图像，或者在位图上进行渲染，并绘制一些控件的位图。它可以是一个自定义控件，派生自 System.Windows.Forms.Control ，或 Panel ，甚至表格。怎么样？我会解释一下。请看我过去的答案：

It''s unbearable to answer this question again and again; it''s too often asked. Please, do this:
http://www.codeproject.com/search.aspx?doctypeid=5&q=SQL+%28images+OR+image%29[^].

Now, it looks like you modify images in PictureBox. Why, on Earth? You can do it, but it''s totally pointless. This control is nothing but a shortcut used to do something very simple: show a static image on screen. If you do anything even a bit more complex, you simply do double work; and a computer also does double work. Control is not an image.

I''ll tell you what to do instead. You should either render image in the control directly, or do in on a bitmap, and draw a bitmap of some control. It could be a custom control derived from System.Windows.Forms.Control, or Panel, or even Form. How? I''ll explain that. Please see my past answers:
