我创建了一个简单的 Office Com 加载项,它在我公司计算机上的其他 PowerPoint 加载项中使用。每次 PowerPoint 启动 AccessViolationException 时,只要我访问 AfterPresentationOpen 事件中的窗口计数属性(请参阅下面的代码),就会发生。
为了缩小问题范围,我创建了两个空白加载项解决方案(Office COM 和 VSTO 加载项)。我在 AfterPresentationOpen 方法中放置了一个断点,并且每次在名为 VSTA_Main 的线程上命中断点并引发此异常。此外,我的 try catch 块没有捕获此异常。一旦我禁用特定的第三方插件,一切都会像魅力一样工作,断点会在主线程上命中,我可以读取 count 属性。
我正在使用 Windows 7 和 Office 2010(都是 x64)。顺便说一句,在我的代码中的“VSTA_Main”线程上引发了所有其他 PowerPoint 事件。我相信实际上应该在我的 appdomain 线程上引发所有事件。
有谁知道我如何处理此错误并避免与此加载项发生任何冲突?
var windows = presentation.Windows;
using (new ComObject(windows))
{
try
{
var count = windows.Count;
if (count == 0)
return;
}
catch (AccessViolationException)
{
}
}
