###### 如果样式库和调用库不是在同一解决方案中，首先要在样式库的属性页中勾选"Generate library layout"

###### 引用代码：

```xml
<ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="ClassLibrary1/Styles/Custom.xaml" />
        <ResourceDictionary Source="ClassLibrary1/Styles/ButtonStyle.xaml"/>
        <ResourceDictionary Source="ClassLibrary1/Styles/ListsStyle.xaml"/>
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
```

或者

```xml
<ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="ms-appx:///ClassLibrary1/Styles/Custom.xaml" />
        <ResourceDictionary Source="ms-appx:///ClassLibrary1/Styles/ButtonStyle.xaml"/>
        <ResourceDictionary Source="ms-appx:///ClassLibrary1/Styles/ListsStyle.xaml"/>
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
```

UWP 引用其他Class Library库中的样式文件

UWP 默认样式保存目录，可以看看系统默认样式加以修改达到自己的效果

```shell
C:\Program Files (x86)\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\UAP\**系统版本号\Generic\generic.xaml

例如:
C:\Program Files (x86)\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\UAP\10.0.17134.0\Generic\generic.xaml
```

UWP 默认样式文件目录位置


##### 概要：

曾经 UWP 只能读写当前应用的存储目录。  
2018 年微软开放了一种更广泛的 IO 读写权限，使 UWP 可以像传统应用程序一样读写几乎所有目录。让 UWP 的能力更上一层楼。

##### 如何开启：

打开 Package.appxmanifest。
添加命名空间 rescap，并将其添加到 IgnorableNamespaces：

```xml
<Package
  ...
  xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"
  IgnorableNamespaces="uap mp uap5 rescap">
...
<Capabilities>
    <rescap:Capability Name="broadFileSystemAccess" />
</Capabilities>
```

##### 创建文件:

```CSharp
//写入文件
    string dir = "d:\\";
    string fileName = "sample.txt";
    string fullPath = Path.Combine(dir, fileName);
    StorageFolder storageFolder = await StorageFolder.GetFolderFromPathAsync(dir);
    StorageFile writeFile = await storageFolder.CreateFileAsync(fileName, CreationCollisionOption.ReplaceExisting);
    await FileIO.WriteTextAsync(writeFile, DateTime.Now.ToString());

    //读取文件
    StorageFile readFile = await storageFolder.GetFileAsync(fileName);

    //全路径读取
    //StorageFile readFile = await StorageFile.GetFileFromPathAsync(fullPath);
    var stream = await readFile.OpenAsync(FileAccessMode.Read);
    ulong size = stream.Size;
    using (var inputStream = stream.GetInputStreamAt(0))
    {
        using (var dataReader = new Windows.Storage.Streams.DataReader(inputStream))
        {
            uint numBytesLoaded = await dataReader.LoadAsync((uint)size);
            string text = dataReader.ReadString(numBytesLoaded);
        }
    }
```

测试发现系统盘根目录还是没有权限，其他目录可以。已经可以满足大多数需求了。
