“Logical resources may be of various types, such as brushes, geometries, styles, and templates.

Placing all those resources in a single file such as App.xaml hinders maintainability. A better

approach would be to separate resources of different types (or based on some other criteria) to

their own files. Still, they must be referenced somehow from within a common file such as App.

xaml so they are recognized.”

为了增加资源文件的可维护性，我们应该使用ResourceDictionary对资源进行：分类、汇总。

如何实现呢？举个例子

1.新建一个WPF Application，在Application中添加一个New Item，选择ResourceDictionary。

譬如，命名为Brushes.xaml，我们用它来存放一些笔刷。打开，我们添加一个笔刷如下：

Brushes.xaml:

2.在App.xaml中Merge则个Resource。

“Open App.xaml. We need to merge external resource dictionaries into the main

application dictionary.”

打开App.xaml，添加如下内容：

3.这样我们就可以在页面中正常使用了。

效果如下：

在实际开发中更常用的做法是：直接在使用的View内部Merge。

效果同上，如下：
