在某些背景下,此应用程序是一个打印应用程序,运行在Autodesk程序revit structure中。它是一个.NET外接程序。
我一直被这些间歇性出现的异常所困扰,这真的很令人沮丧。如何调试这些?
通常情况下,建议不要在revit加载项中使用多线程,我在这个特定实例中所做的就是从revit中读取一些信息,然后在缺少某些信息时显示一个对话框。我不知道为什么会导致accessvioldationexceptions

因此,在按钮处,您可以看到我的filePostprocessor.setParameters方法是从中引发消息框的地方。但是,当这种情况发生时,许多其他事情都与引发事件有关(Windows窗体代码的一部分?)然后顶部有一些我不知道的欧特克的东西。
我还注意到了“exceptionwrapper.internalrealcall”这一点对我有帮助吗,在我能看到的某个地方有一个真正的异常对我有一半的帮助吗?
这里有什么我做错的地方吗?我的代码只是一些东西的单线程循环。
我意识到这对你们来说并不是很多信息,你们可以说‘吊杆358线是你们的问题’,但是任何关于调试/避免这些类型错误的建议都是有帮助的。虽然我使用dsofile.dll在文件上设置了一些自定义属性,但我并没有做任何非托管的事情,但这只是我正在做的事情上面的几行代码,我认为它是单线程的?
