[2.0] Close excel?

[Arrow_Raider]

I am automating excel (by adding a COM reference to excel) in my .net application. I can't figure out how to close my instance of the excel application.
I have created the excel instance with the following line:
Excel.Application excelApp = new Excel.ApplicationClass();

Once I'm done with excelApp, I need to close it. How do I do this?

I am not sure about this, but it should be excelApp.Quit(); (or maybe Close() or similar).
