How to write this Code in EPPLUS?
Microsoft.Office.Interop.Excel.Workbook Workbook = Excel.Workbooks.Add(System.Type.Missing);
This is a boilerplate for creating a new spreadsheet in EPPlus:
FileInfo newFile = new FileInfo(fileName);
ExcelPackage package = new ExcelPackage(newFile);
ExcelWorksheet ws = package.Workbook.Worksheets.Add("Sheet1");
// Do some stuff
ws.Cells["A1"].Formula = "=TODAY()";
ws.Cells[2, 1].Value = "Hello World";
package.Save();
You could do it with the empty constructor (no file info specified), but you'll eventually have to declare that, so I always find it useful to do it up front.
