How to set Image Source in C# to XAML Static Resource programmatically?
提问by Danny Beckett
I have this ResourceDictionaryin Main.xaml:
我有这样ResourceDictionary的Main.xaml：
<Window.Resources>
<ResourceDictionary>
<BitmapImage x:Key="Customer" UriSource="Icons/customer.png"/>
<BitmapImage x:Key="Project" UriSource="Icons/project.png"/>
<BitmapImage x:Key="Task" UriSource="Icons/task.png"/>
</ResourceDictionary>
</Window.Resources>
I initially set the image using:
我最初使用以下方法设置图像：
<Image Name="TypeIcon" HorizontalAlignment="Left" VerticalAlignment="Center"
Source="{StaticResource Customer}" Height="16" Width="16"/>
I'm trying to change TypeIcon's Sourcefrom Customerto Projectin a C# method.
我正在尝试使用 C# 方法将TypeIcon'sSource从Customer更改为Project。
I've tried using:
我试过使用：
TypeIcon.Source = "{StaticResource Project}";
But I get this error:
但我收到此错误：
Cannot implicitly convert type
stringtoSystem.Windows.Media.ImageSource
不能将类型隐式转换
string为System.Windows.Media.ImageSource
I've tried defining the image using new ImageSource(), but this doesn't work either.
我试过使用 定义图像new ImageSource()，但这也不起作用。

After much Googling, whilst writing this question, I figured out how to do it:
经过多次谷歌搜索，在写这个问题时，我想出了如何去做：
TypeIcon.Source = (ImageSource) Resources["Project"];

You can use the ImageSourceConverterclass to get what you want, for example:
您可以使用ImageSourceConverter该类来获取您想要的内容，例如：
img1.Source = (ImageSource)new ImageSourceConverter().ConvertFromString("/Assets/check.png");

It is not for static resources but perhaps will be useful anyway... :)
它不适用于静态资源，但无论如何可能会有用...... :)
