在WPF中的同一解决方案中，在运行时在不同的类库项目中更改资源文件(Change Resource file at runtime in different class library project in same solution in WPF)

 我有这些项目的解决方案： 
 
 1. Clinica （Type是Windows应用程序），（ MainWindow.xaml在这里） 
 
 2. Ferhad.Wpf.Core （类型是类库），（有三个文件： Resources.xaml ， OrangeResource.xaml ， BlueResource.xaml ） 
 
 Resources.xaml看起来像这样： 
 
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="pack://application:,,,/Ferhad.Wpf.Core;component/BlueResource.xaml"/>
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
 
 现在，从MainWindow.xaml.cs我想清除并将OrangeReource.xaml添加到Resources.xaml 。 
 
 我怎么能这样做：到目前为止我试过这个： 
 
string fileName = "pack://application:,,,/Ferhad.Wpf.Core;component/OrangeReSource.xaml";
if (System.IO.File.Exists(fileName))
{
    using (FileStream fs = new FileStream(fileName, FileMode.Open))
    {
        ResourceDictionary dic = (ResourceDictionary)XamlReader.Load(fs);

        string fileNameR = "pack://application:,,,/Ferhad.Wpf.Core;component/Resources.xaml";
        if (System.IO.File.Exists(fileNameR))
        {
            using (FileStream fsR = new FileStream(fileNameR, FileMode.Open))
            {
                ResourceDictionary dicR = (ResourceDictionary)XamlReader.Load(fsR);
                dicR.MergedDictionaries.Clear();
                dicR.MergedDictionaries.Add(dic);
            }
        }
    }
}
 
 谢谢。 

I have a solution with these projects:
 
1.Clinica (Type is Windows Application),(MainWindow.xaml is here)
 
2.Ferhad.Wpf.Core (Type is Class Library), (There are three files: Resources.xaml, OrangeResource.xaml, BlueResource.xaml)
 
The Resources.xaml looks like that:
 
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="pack://application:,,,/Ferhad.Wpf.Core;component/BlueResource.xaml"/>
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
 
Now, from MainWindow.xaml.cs I want to clear and add OrangeReource.xaml to Resources.xaml.
 
How can i do that: So far I have tried this:
 
string fileName = "pack://application:,,,/Ferhad.Wpf.Core;component/OrangeReSource.xaml";
if (System.IO.File.Exists(fileName))
{
    using (FileStream fs = new FileStream(fileName, FileMode.Open))
    {
        ResourceDictionary dic = (ResourceDictionary)XamlReader.Load(fs);

        string fileNameR = "pack://application:,,,/Ferhad.Wpf.Core;component/Resources.xaml";
        if (System.IO.File.Exists(fileNameR))
        {
            using (FileStream fsR = new FileStream(fileNameR, FileMode.Open))
            {
                ResourceDictionary dicR = (ResourceDictionary)XamlReader.Load(fsR);
                dicR.MergedDictionaries.Clear();
                dicR.MergedDictionaries.Add(dic);
            }
        }
    }
}
 
Thanks.
