wpf中有MergedGradientBrush吗？
假设我有两把刷子。
一个是从暗到亮的线性渐变画笔
一种是从深色到浅色的放射状画笔。
如何合并画笔，以便在应用它们时可以同时应用两者。

我如何（在 WPF/XAML 中）将两者合并为一个渐变，然后引用它？ （这是 Menendez 先生来自 Codeproject 的图片）
Suppose I had two brushes.
One that was a linear gradient brush that was from Dark to light
One was a radial brush that went from Dark to light.
How could I merge the brushes so that when I apply them, I can apply both at once.

How could I (In WPF/XAML) merge both into one gradient and then refer to that?

简而言之，没有办法将两个不同的渐变画笔“合并”为一个。但是，有一些解决方法可以帮助您完成工作。例如，您可以创建两个重叠的
Border元素（使用Grid），一个使用线性画笔，另一个使用渐变画笔。然后，您可以将画笔中每种颜色的 Alpha 分量设置为 50% 透明度。通过这种方式，画笔将被渲染在另一个之上，但两者都会显示得同样好。Short answer, there is no way to "merge" two different gradient brushes into one. However, there are workarounds that will get the job done for you. You could, for example, create two overlaid
Borderelements (using aGrid), one with the linear brush and the other with the gradient brush. You could then set the alpha component of each of the colors in the brushes to 50% transparency. In that manner, the brushes would be rendered one on top of the other, but both would show up equally well.
