如何在WPF中只更改一个合并的资源字典？

Question

我们的应用程序使用ResourceDictionary作为其样式。此资源字典本身包含资源字典：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<ResourceDictionary.MergedDictionaries>
    <ResourceDictionary Source="BridgeIt5/General.xaml" />
    <ResourceDictionary Source="BridgeIt5/Brushes.xaml" />
    <ResourceDictionary Source="BridgeIt5/Constants.xaml" />
    <ResourceDictionary Source="BridgeIt5/Button.xaml" />
     ...
</ResourceDictionary.MergedDictionaries>

所以，现在，根据构建配置，我们只想更改Brushes.xaml合并资源字典。怎么办呢？

Answer 1

如果您可以在运行时设置配置，则可以在启动期间执行此操作：

var resourceDictionary = new ResourceDictionary
{
    // Pick uri from configuration
    Source = new Uri("BridgeIt5/Brushes.xaml"),
};

Application.Current.Resources.MergedDictionaries.Add(resourceDictionary);
