是什么在WPF應用程序中導致XamlParseException？

[英]What is causing XamlParseException in WPF application?

問題描述

更新：在問題點之后（在兩個應用程序中）都發生了control.Resources.dll的加載，因此很可能是紅色鯡魚。

我有兩個應用程序，一個運行良好，一個不會出現各種異常。 它們都是WPF應用程序，都在.NET 3.5和Windows7下運行。 它們都建立在同一組引用/依賴關系上。 它們基本上是相同的程序。 我已經手動比較了它們的主要文件，以尋找問題的根源。

在啟動過程中會出現問題。 異常始終是XamlParseException，但是原因（從SQL異常到多點觸控異常）不盡相同。 直接堆棧為： 

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'.

根據我在這里和其他地方的閱讀，這實際上可能是由於資源DLL無法正確加載或資源沖突引起的。

我已經運行了Process Explorer，並且觀察到在工作程序中的.NET程序集選項卡中，存在多個非工作程序中不存在的Controls.resources.dll文件條目。

我認為這些dll也應該加載到非工作程序中； 會有人對他們為什么不會有任何想法嗎？

編輯添加：這是它正在嘗試處理的xaml文件的編輯版本：

我遇到了同樣的問題，因此我發布了對我有用的解決方案。 我使用第三方DLL在WPF應用程序中創建用戶控件。 當我直接啟動我的應用程序時，它可以正常工作-但是，當我從另一個應用程序中啟動它（這是正常用法）時，它卻失敗了，並出現了與上述完全相同的問題。 為了解決它，我將用戶控件的變量聲明從XAML移到了后面的代碼中。 這意味着在創建變量並將其實例化時，現在已加載相同的DLL，因此沒有沖突。
