winforms透明背景? [英] Transparent background on winforms?

问题描述

我想让我的 windows 窗体透明，所以删除了边框、控件和只留下窗体框的所有内容，然后我尝试将 BackColor 和 TransparencyKey 设置为透明但它没有成功，因为 BackColor 不接受透明颜色.在四处搜索后，我在 msdn 上找到了这个:

I wanted to make my windows form transparent so removed the borders, controls and everything leaving only the forms box, then I tried to the BackColor and TransparencyKey to transparent but it didnt work out as BackColor would not accept transparent color. After searching around I found this at msdn:

SetStyle(ControlStyles.UserPaint, true);
SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
SetStyle(ControlStyles.SupportsTransparentBackColor, true);
this.BackColor = Color.Transparent;
this.TransparencyKey = BackColor;

不幸的是，它也不起作用.我仍然得到灰色或任何其他选定的颜色背景.

Unhappyly it did not work either. I still get the grey or any other selected color background.

我想做的就是让窗体透明，这样我就可以使用一个背景图像，就好像它是我的窗体一样.

All I wanted to do is to have the windows form transparent so I could use a background image that would act as if it was my windows form.

我在这里搜索了很多关于不透明度的主题，这不是我想要的，还看到了一些关于我正在尝试但尚未找到答案的方法.

I searched around here and saw many topics in regards opacity which is not what I am looking for and also saw some in regards this method I was trying but have not found an answer yet.

希望任何人都可以照亮我的道路.

Hope anyone can light my path.

推荐答案

我之前使用的方式是对BackColor使用一种百搭的颜色(没有人会使用的颜色)，然后设置透明度键到那个.

The manner I have used before is to use a wild color (a color no one in their right mind would use) for the BackColor and then set the transparency key to that.

this.BackColor = Color.LimeGreen;
this.TransparencyKey = Color.LimeGreen;
