如何在应用程序资源中使用xaml图形？

Question

我已经从矢量图形（SVG）转换了XAML图形。我想要使​​用它的方法是为每个图像制作XAML文件，然后将其放在项目的某个文件夹中。在application.resources中，创建一个引用键以在项目中使用它。

问题我发现它似乎我在application.resources做的是错误的。我用了

  

'ResourceDictionary'

但它会引发异常。

  

    

'设置属性'System.Windows.ResourceDictionary.Source'引发了一个异常。

  

请帮我解决这个问题。 提前谢谢。

我想在Application.Resources里面的资源文件（在我的项目中是app.xaml）中使用xaml图像，然后另一个页面可以将其称为StaticResource

另外，我想将此图像用作按钮。

我有以下xaml，我将其保存为新文件'button.xaml'。然后我想在application.resources中添加一个引用链接，将其他页面中的这个按钮用作按钮。

好的，我仍然不确定inside the then the other page，但让我尝试提供帮助。

不要以为你的App.Xaml有这样的东西：

<Application.Resources>

  <Canvas x:Key="TestImage">
    <Path Fill="#ff000000" Data="F1 M 68.240234,42.634277 L 69.554688,6.311035 L 69.414063,7.050293 C 69.665039,6.368164 70.482422,5.000000 71.210938,5.000000 L 79.306641,5.000000 C 80.060547,5.000000 80.898438,6.468750 81.104492,7.052734 L 80.963867,6.326172 L 82.497070,42.649414 L 84.995117,40.043945 L 65.742188,40.043945 L 68.240234,42.634277 Z M 87.493164,42.438477 L 85.959961,6.115234 L 85.944336,5.741211 L 85.819336,5.388672 C 85.113281,3.387207 82.946289,0.000000 79.306641,0.000000 L 71.210938,0.000000 C 67.566406,0.000000 65.401367,3.388672 64.697266,5.391113 L 64.571289,5.750000 L 64.556641,6.130371 L 63.244141,42.453613 L 63.150391,45.043945 L 65.742188,45.043945 L 84.995117,45.043945 L 87.602539,45.043945 L 87.493164,42.438477 Z"/>
  </Canvas>

</Application.Resources>

请注意它是一个画布中的路径（因此，如果你将它放入某个东西，它会绘制一些东西），重要的是x:Key="TestImage。

现在，我们假设在不同的地方/页面/控件中，您想要使用您放在上面的资源中的图像，您只需要做的就是：

<Grid>
    <ContentControl Content="{StaticResource TestImage}" />
</Grid>

你会看到你的形象。

您可以在ResourceDictionary中的不同xaml文件中定义，只需确保将该字典合并到资源中，以便找到它。

（看起来像是：

<Page.Resources>
  <ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
      <ResourceDictionary Source="your_file_name_here.xaml"/>
    </ResourceDictionary.MergedDictionaries>
  </ResourceDictionary>
</Page.Resources>

有关详细信息，请参阅here。

修改 你添加的画布没有键...你应该在资源字典中有它，它应该有一个键，所以你可以将它称为StaticResource

另一个编辑......
您需要在要访问以下代码的窗口/ usercontrol中包含此代码：

<Window.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="FolderNameHere/weight.xaml"></ResourceDictionary>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Window.Resources>

（如果你在用户控件中，显然将窗口更改为用户控件...） 请注意，文件夹名称前面没有/或\（假设您将权重放在名为FolderNameHere的文件夹中，您可以使用上述代码与其达成。

是的，你放在最后的代码将放在那个文件中，文件看起来像：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Canvas x:Key="TestCanvas" >
    <Path Fill="#ff000000" Data="all the points go here"/>
</Canvas>
</ResourceDictionary>

只有你有别的东西而不是画布。
