http://msdn.microsoft.com/en-us/library/microsoft.office.tools.excel.worksheet.get_range.aspx it says to use the Range property instead of get_Range(Object Cell1, Object Cell2).
They are both doing the same thing, Gets a Microsoft.Office.Interop.Excel.Range object that represents a cell or a range of cells. So, what's the difference except that this is a method and another is a property? Why are they pointing on use of Range[], what's the reason for it?
