using Microsoft.Office.Interop.Excel;
using Microsoft.Office.Core;
//.....................

Microsoft.Office.Interop.Excel.Application vExcel =
new Microsoft.Office.Interop.Excel.Application();

using Excel = Microsoft.Office.Interop.Excel;

Excel.Application oExcel = null;
Excel.Workbooks oWorkbooks = null;
Excel._Workbook oWorkbook = null;
Excel.Sheets oSheets = null;
Excel._Worksheet oSheet = null;
Excel.Range oRange = null;
//Excel.Font oFont = null;

// Frequenty-used variable for optional arguments.
object missing = System.Reflection.Missing.Value;

//Start Excel and get Application object.
oExcel = new Excel.Application();
//Excel项目可见
//oExcel.Visible = true;

//Get a new workbooks
oWorkbooks = (Excel.Workbooks)oExcel.Workbooks;
//Get a new workbook.
