我正在使用WPF TextBlock，但是当文本太长时，文本会被切断。 是否有AutoScroll功能？

Question

My TextBlock has for example 50x50 pixels to display text, however if there is more text, I want a user to be able to scroll. Is there an autoscroll feature for this control?

Should I use a different control better suited for this task?

Here's a couple of pics to illustrate the problem:

This one works fine because the text fits in snugly:

This one doesn't seem correct. Text is cut off.

Just in case someone comes into the same problem. Just wrap the textBlock with a control. Works like a charm!

<ScrollViewer Background="Black">
    <TextBlock x:Name="textBlockBackStory" 
               FontSize="12" 
               Foreground="Orange" 
               TextWrapping="Wrap"                       
               Background="Black" 
               TextDecorations="None">
                            Backstory here.
    </TextBlock>      
</ScrollViewer>

您可以将文本块放在ViewBox中，这样字体就会调整以显示整个文本。
