c# - 无法加载文件或程序集 'Xceed.Wpf.Toolkit

Question

我正在为另一个应用程序 Autodesk Revit 开发一个插件，它是作为一个单独的 DLL 类库构建的。我正在尝试使用 Wpf Tool Kit Property grid在我的一个 WPF 窗口中。属性网格在 Visual Studio 中显示良好，智能感知也能正常工作。但是，当我尝试在加载加载项的情况下启动 Revit 时，出现以下异常。

System.Windows.Markup.XamlParseException occurred

通常，当我想从 Revit 插件引用第 3 方程序集时，我只需确保将第 3 方 DLL 复制到与我的插件 DLL 相同的位置。我检查了一下，Xceed.Wpf.Toolkit.dll 被复制到包含我的插件 DLL 的目录。

我从错误中的日志消息中注意到它正在 Revit 程序目录中查找 DLL。将 Xceed.Wpf.Toolkit.dll 复制到此目录后，我不再收到错误。

但是，我有现有的插件部署工具，这些工具依赖于插件文件位于它们自己的隔离文件夹中。

那么，有没有人知道如何让插件找到 WPF 工具包库？

因此，从 2014 年开始，我找到了一个新的更好的解决方案来解决我的这个问题。

今天我遇到了同样的问题，即从程序集中加载 WPF 控件会抛出 XamlParseException，只是这次是我创建的 WPF 控件库程序集。

我尝试将 DLL 移动到与 EXE 相同的文件夹中，并且像以前一样解决了问题。

经过一番搜索，我在 telerik.com 论坛上发现了这个问题: http://www.telerik.com/forums/xamlparseexception-could-not-load-file-or-assembly

事实证明，如果您只是通过添加 x:Name 属性为控件命名，这将在代码隐藏中添加对控件的引用，并且出于某种原因解决了问题加载程序集。

  <!--This causes a XamlParseException -->
  <mylib:MyCustomControl />

  <!-- This works -->
  <mylib:MyCustomControl x:Name="foobar"/>
