如何从InnerException获取DirectoryServicesCOMException？

Question

如何从InnerException获取DirectoryServicesCOMException ExtendedErrorMessage？ 程序只捕获“catch（例外e）”，所以这不起作用：

try
{
   ...
}
   catch (DirectoryServicesCOMException e)
{
   throw e;
}

screen

类似的东西：

try
{
   ...
}
   catch (Exception e)
{
   throw e.InnerException.DirectoryServicesCOMException ....;
}

你应该可以这样做：

if (e.InnerException is DirectoryServicesCOMException)
{
    DirectoryServicesCOMException innerException = (DirectoryServicesCOMException)e.InnerException;
    // do whatever is correct with these kind of exception
}
