c# - 命名空间中不存在 wpf 资源字典？

Question

我正在使用 .net 4.5.2我不知道为什么我的项目继续说资源丢失。我已将我的 mainWindow.xaml 放在一个文件夹中，并重新设置应用程序的路径以定位其位置。真正奇怪的是它在 visual studio 中正确显示，但当我尝试编译它时出错，说项目中不存在“主题”命名空间。

Severity Code Description Project File Line Error CS0234 The type or namespace name 'Themes' does not exist in the namespace 'WpfApplication1' (are you missing an assembly reference?) WpfApplication1 C:\Users\jmartini\Projects\wpf_Styling_4.5.2\WpfApplication1\WpfApplication1\obj\Debug\View\MainWindow.g.i.cs 33

这是我的代码...

MainWindow.xaml

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfApplication1"
        mc:Ignorable="d"
        Title="MainWindow" Height="200" Width="250"
        WindowStartupLocation="CenterScreen">
    <DockPanel>
        <Button Content="Push It!" Width="70" VerticalAlignment="Center" HorizontalAlignment="Center"/>
    </DockPanel>
</Window>

JMStyles.xaml

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:WpfApplication1.Themes">

    <Style TargetType="{x:Type Button}">
        <Setter Property="Background" Value="Red" />
        <Setter Property="Foreground" Value="White" />
        <Setter Property="FontSize" Value="15" />
        <Setter Property="SnapsToDevicePixels" Value="True" />
    </Style>

</ResourceDictionary>

App.xaml

<Application x:Class="WpfApplication1.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:WpfApplication1"
             StartupUri="View/MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Themes/JMStyles.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

让它工作的解决方案...我从样式页面中删除了这一行:

xmlns:local="clr-namespace:WpfApplication1.Themes"

原创

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

    <Style TargetType="{x:Type Button}">
        <Setter Property="Background" Value="Red" />
        <Setter Property="Foreground" Value="White" />
        <Setter Property="FontSize" Value="15" />
        <Setter Property="SnapsToDevicePixels" Value="True" />
    </Style>

</ResourceDictionary>

我删除了这行代码

xmlns:local="clr-namespace:WpfApplication1.Themes"

从下面的样式页面文件内容...

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:WpfApplication1.Themes">

    <Style TargetType="{x:Type Button}">
        <Setter Property="Background" Value="Red" />
        <Setter Property="Foreground" Value="White" />
        <Setter Property="FontSize" Value="15" />
        <Setter Property="SnapsToDevicePixels" Value="True" />
    </Style>

</ResourceDictionary>
