是什么导致了 WPF 应用程序中的 XamlParseException
本文关键字:XamlParseException 应用程序 WPF 是什么 | 更新日期: 2023-09-27 18:33:13
更新:控件的加载。资源.dll发生在故障点之后(在两个应用程序中(,因此这可能是一个红鲱鱼。
我有两个应用程序,一个运行良好,另一个不会因各种异常而启动。 它们是在 .NET 3.5 和 Windows7 下运行的 WPF 应用程序。它们都是基于同一组引用/依赖项构建的。 它们基本上是相同的程序。我手动比较了他们的主要文件以寻找问题来源,但无济于事。
启动过程中出现问题。异常始终是 XamlParseException,但原因(从 SQL 异常到多点触控异常(不同。直接堆栈为:
Unable to cast object of type 'System.Windows.Controls.ListView' to type 'Lightning.Controls.Configuration.MaterialsImportExportControl'.
Error at object 'System.Windows.Controls.ListView' in markup file 'Lightning.UI.Controls;component/configuration/materials/xaml/materialsimportexportcontrol.xaml'.

根据我在这里和其他地方的阅读,这实际上可能是由资源 DLL 未正确加载或资源冲突引起的。
我运行了Process Explorer,并观察到在工作程序的.NET程序集选项卡中,有多个用于Controls.resources的条目.dll这些文件在非工作程序中不存在。
我认为这些dll也应该加载到非工作程序中;有人知道为什么它们不会加载吗?
编辑以添加:下面是它尝试处理的 xaml 文件的编辑版本:

奇怪的是,我可以在程序早期的循环中执行导致 ManipulationProcessor 实例化超过 100 万次的代码,而只显示内存不足异常 - 看不到E_NOINTERFACE。哈伦夫。
我遇到了同样的问题,所以我发布了对我有用的解决方案。我使用第三方 DLL 在 WPF 应用程序中创建用户控件。当我直接启动我的应用程序时,它工作正常 - 但是当我从另一个应用程序启动它时(这是正常用法(,它失败了,问题与上面完全相同。为了解决这个问题,我将用户控件的变量声明从 XAML 移到了后面的代码。这意味着在创建变量并实例化变量时,现在将加载相同的 DLL,因此不会发生冲突。
