c# - Intercepting an exception inside IDisposable.Dispose

In the IDisposable.Dispose method is there a way to figure out if an exception is being thrown?

using (MyWrapper wrapper = new MyWrapper())
{
    throw new Exception("Bad error.");
}

If an exception is thrown in the using statement I want to know about it when the IDisposable object is disposed.

No, there is no way to do this in the .Net framework, you cannot figure out the current-exception-which-is-being-thrown in a finally clause.

See this post on my blog, for a comparison with a similar pattern in Ruby, it highlights the gaps I think exist with the IDisposable pattern.

Ayende has a trick that will allow you to detect an exception happened, however, it will not tell you which exception it was.
