WPF如何调用不同类库之间的文件夹呢？比如：A类库中的Resources文件夹，B类库如何访问A类库中的Resources文件夹呢？

Answer 1

你好，

先建两个类库，名字分别为A和B，如图所示:

其中Dictionary_A.xaml的代码为：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:A">
    
    <Style x:Key="StyleA" TargetType="{x:Type Button}">
        <Setter Property="Background" Value="Red"/>
    </Style>
</ResourceDictionary>

Dictionary_B.xaml的代码为：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:B">
    <Style x:Key="StyleB" TargetType="{x:Type Button}">
        <Setter Property="Background" Value="LightYellow"/>
    </Style>
</ResourceDictionary>

在类库B中的reference中引入A，UserControl_B.xaml的代码为：

<UserControl x:Class="B.UserControl_B"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:B"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">
    <UserControl.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/A;component/Dictionary_A.xaml"/>
                <ResourceDictionary Source="/B;Component/Dictionary_B.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </UserControl.Resources>
    <StackPanel>
        <Button x:Name="button_A" Content="Use Dictionary_A" Style="{StaticResource StyleA}" Width="150" Height="30"></Button>
        <Button x:Name="button_B" Content="Use Dictionary_B" Style="{StaticResource StyleB}" Width="150" Height="30"></Button>
    </StackPanel>
</UserControl>

谢谢

非常感谢您的回复，谢谢!

如果A类中有个Resources文件夹的话，在B类中如何访问到这个文件夹呢？我的目的是想访问到这个Resources文件夹，谢谢！

Answer 3

你好，

修改pack的uri就可以：

  <ResourceDictionary Source="pack://application:,,,/A;component/Resources/Dictionary_A.xaml"/>

谢谢

Answer 4

你好，

用法是一样的，比如我在A/Resources中放入一张图片名字为Myico.ico，在B中的UserControl使用：

 <Image Source="pack://application:,,,/A;component/Resources/Myico.ico" Width="100" ></Image>

谢谢
