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
You need to declare the variable as Microsoft.Office.Interop.Excel.Application, but instantiate it as Microsoft.Office.Interop.Excel.ApplicationClass.
Microsoft.Office.Interop.Excel.Application
Microsoft.Office.Interop.Excel.ApplicationClass
