How close Word object from C#?

[Ronald S. Cook]

I'm trying to open the Word object model, read some text and then close the
document and app. But I get this when trying to close the document and
application...

Ambiguity between method 'Word._Document.Close(ref object, ref object, ref
object)' and non-method 'Word.DocumentEvents2_Event.Close'. Using method
group. D:\Win\Nightclub\Nightclub\frmMain.cs
Ambiguity between method 'Word._Application.Quit(ref object, ref object, ref
object)' and non-method 'Word.ApplicationEvents4_Event.Quit'. Using method
group. D:\Win\Nightclub\Nightclub\frmMain.cs

Any idea how to get around it?

Thanks,
Ron
