未能分配給屬性'Windows.UI.Xaml.Controls.ContentControl.Content'

在我的Windows 10應用程序中，我想從資源文件中設置按鈕內容。在設計器中，來自資源文件的矢量圖像是可見的。但在運行時會發生以下異常： Demo.UI.W10.exe中出現類型爲'Windows.UI.Xaml.Markup.XamlParseException'的異常，但未在用戶代碼中處理 WinRT信息：未能分配給屬性'Windows.UI.Xaml.Controls.ContentControl.Content'。 [Line：15 Position：17] 附加信息：無法找到與此錯誤代碼關聯的文本。未能分配給屬性'Windows.UI.Xaml.Controls.ContentControl.Content'

這是我resourche字典Icons.xaml至極持有與鍵無線視框控制的矢量圖像：

這是我的App.xaml，我添加了圖標。在MergedDictionaries XAML資源文件：

<Application 
x:Class="Demo.UI.W10.App"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
xmlns:local="using:Demo.UI.W10" 
RequestedTheme="Light"> 
<Application.Resources> 
    <ResourceDictionary> 
     <ResourceDictionary.MergedDictionaries> 
      <ResourceDictionary Source="Assets/Icons.xaml"/> 
      <ResourceDictionary Source="Assets/Styles.xaml"/> 
     </ResourceDictionary.MergedDictionaries> 
    </ResourceDictionary> 
</Application.Resources>

在我的mvvmcross頁面中，我使用資源文件中的矢量圖像WiFi來設置按鈕內容。

<views:MvxWindowsPage 
x:Class="Demo.UI.W10.Views.ConnectionView" 
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
xmlns:local="using:Demo.UI.W10.Views"

xmlns:views="using:Cirrious.MvvmCross.WindowsUWP.Views" 
mc:Ignorable="d"> 
<Page.Resources> 
    <vm:ConnectionViewModel x:Key="ViewModel"/> 
</Page.Resources> 
<Grid> 
    <Button Content="{StaticResource Wifi}" Command="{Binding DemoCommand, Source={StaticResource ViewModel}}" Style="{StaticResource BtnMenuStyle}"/> 
</Grid>

我如何使用矢量圖像從資源字典作爲按鈕的內容？

你可以將資源的一個DataTemplate內：

<DataTemplate x:Key="Wifi"> 
     <Viewbox > 
      <Grid Width="48" Height="48" Visibility="Visible"> 
       <Path Data="M16.104004,15.776998C17.199005,15.776998 18.086014,16.664998 18.086014,17.759999 18.086014,18.855977 17.199005,19.742999 16.104004,19.742999 15.009003,19.742999 14.12001,18.855977 14.12001,17.759999 14.12001,16.664998 15.009003,15.776998 16.104004,15.776998z M16.104004,10.558985C19.327011,10.558985,22.057007,12.679008,22.975006,15.601004L21.118011,16.756978C20.652008,14.412986 18.584015,12.646995 16.104004,12.646995 13.580002,12.646995 11.486008,14.474997 11.067001,16.87798L9.1930084,15.730001C10.070007,12.741997,12.831009,10.558985,16.104004,10.558985z M16.028015,5.2879915C21.153015,5.2879915,25.555008,8.378993,27.476013,12.796989L25.771011,13.859C24.221008,9.9980106 20.443008,7.2719988 16.028015,7.2719988 11.586014,7.2719988 7.7890015,10.031 6.2570038,13.929984L4.5440063,12.879997C6.4450073,8.4169874,10.871002,5.2879915,16.028015,5.2879915z M16.028015,0C23.047012,5.5224518E-08,29.114014,4.0700049,32,9.9789981L30.128006,11.144982C27.639008,5.8550076 22.262009,2.1920154 16.028015,2.1920151 9.7550049,2.1920154 4.3480072,5.9020047 1.881012,11.24801L0,10.094995C2.8630066,4.1239905,8.9640045,5.5224518E-08,16.028015,0z" Stretch="Uniform" Fill="#FF000000" Width="48" Height="48" Margin="0,0,0,0" RenderTransformOrigin="0.5,0.5"> 
       </Path> 
      </Grid> 
     </Viewbox> 
    </DataTemplate>

而現在只需

<Button ContentTemplate="{StaticResource Wifi}"/>

你可以使用它，你需要儘可能多的時間。

感謝它的工作！現在我必須找出Content和ContentTemplate之間的區別。 – Rene

我來到這裏是因爲有同樣的問題和相同的senario，thx的答案，你可以請@Juan解釋爲什麼這不工作？爲什麼將靜態資源分配給內容屬性不起作用？ – AymenDaoudi

未能分配給屬性'Windows.UI.Xaml.Controls.ContentControl.Content'
