問題描述

我想讓我的 windows 窗體透明，所以刪除了邊框、控件和只留下窗體框的所有內容，然后我嘗試將 BackColor 和 TransparencyKey 設置為透明但它沒有成功，因為 BackColor 不接受透明顏色.在四處搜索后，我在 msdn 上找到了這個:

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選定的顏色背景.

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

我想做的就是讓窗體透明，這樣我就可以使用一個背景圖像，就好像它是我的窗體一樣.

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.

我在這里搜索了很多關于不透明度的主題，這不是我想要的，還看到了一些關于我正在嘗試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.

推薦答案

我之前使用的方式是對BackColor使用一種百搭的顏色(沒有人會使用的顏色)，然后設置透明度鍵到那個.

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;
