c# - 窗口初始化时出现 XamlParseException

Question

当我打开我的 WPF 窗口时出现了这个错误，我不知道是什么导致了这个错误，也不知道如何消除它。错误突出显示并指向 </Border>在底部。

'Initialization of 'Outlook_Add_In_Test.WPFExiEvent' threw an exception.' Line number '91' and line position '11'.

我的 WPF 代码:

Answer 1

根据您在评论中所说的内容，它似乎与 MahApps Metro 主题相关联。

看看这个:https://github.com/MahApps/MahApps.Metro/issues/582

如果您引用了 Windows Interactivity dll，请尝试将其删除。

以后记得像 SLaks 说的那样检查 InnerException。您可以从中学到更多，并为您提供更多工作。
