C# -Excel interoperability

Question

I want to call Excel Sheet from C# 4.0 (VS 2010 Express Edition) .

When i declare ,

Microsoft.Office.Interop.Excel.ApplicationClass excel =
    new Micro         


        

Answer 1

Solved:

Excel.ApplicationClass derives from Excel.Application interface and one can even instantiate Excel using Excel.Application interface. Rewriting this code as below produces exact same results:

Excel.Application xlapp = new Excel.Application();
