An unhandled exception of type 'System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll 

Additional information: 'Provide value on 'System.Windows.Baml2006.TypeConverterMarkupExtension' threw an exception.' Line number '54' and line position '22'.

我試圖運行下面的XAML件WPF嘗試了一個簡單的人物動畫

        </BeginStoryboard> 
       </EventTrigger> 
      </TextBlock.Triggers> 
     </TextBlock> 
    </Border>

我想動畫「拍拍手」，當遇到這個錯誤時，拋出一個異常時，文本塊在加載窗口時加載。謝謝

我認爲問題在於你試圖綁定到TextBlock.Content。但是TextBlock具有「Text」屬性，它不是ContentControl。所以如果你把它改爲「文本」，你應該沒問題。
