Question

您好我有奇怪的问题。在Visual Studio设计器中，我的应用程序看起来很正常 - 颜色看起来就像我设置它们。但是，如果我启动一个应用程序，几乎所有主窗口上的控件都会变黑背色

这是我的主窗口的xaml代码（有点长）

Answer 1

顶级窗口的背景：

 Background="#200077EF"

没有出现在设计师中，但是当你运行它时它会“流血”，因为网格背景是透明的。

更新：真正的问题似乎是窗口背景的alpha通道。在设计师中，背景的“背后”颜色看起来是白色的，在运行时，背景的“背后”颜色看起来是黑色。由于窗口背景的alpha没有为你做任何事情，为了让设计师和运行时同意只使用一个坚实的窗口背景：

Background="#E0EEFD"

其颜色等于7/8白色+ 1/8＃0077EF。

wpf - 设计师看起来与应用程序不同
