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

问题描述

我想使我的窗户形成透明的，所以删除了边界，控制和一切只剩下形式框，然后我试图把背景色和TransparencyKey透明，但它没有工作了作为背景色不会接受透明的颜色。周围搜索后，我发现这个在MSDN：

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;

Unhappyly它也不能工作。我仍然得到灰色或任何其他选择的颜色背景。

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

所有我想做的事就是有Windows窗体透明，这样我可以使用，如果它是我的窗口形式，将采取行动的背景图像。

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.

我搜索在这里，看到不透明度方面的许多主题这是不是我找的，也看到了一些问候这个方法我是想，但还没有找到答案。

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.

希望每个人都可以照亮我的道路。

Hope anyone can light my path.

推荐答案

我以前用的方式是使用背景色野生色（颜色没有一个心智正常的人会使用），然后设置透明度的关键了这一点。

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;
