excel生成多个sheet .net

Microsoft.Office.Interop.Excel.Application myExcel = new Microsoft.Office.Interop.Excel.Application(); //生成一个excel对象
Microsoft.Office.Interop.Excel.Workbook workbook = myExcel.Workbooks.Add(Microsoft.Office.Interop.Excel.XlWBATemplate.xlWBATWorksheet); //生成一个workbook对象

Microsoft.Office.Interop.Excel.Worksheet Sheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[1];//取得第一个sheet

Object Nothing = System.Reflection.Missing.Value;

Microsoft.Office.Interop.Excel.Worksheet Sheet1 = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets.Add(Nothing, Sheet, Nothing, Nothing);//添加一个sheet 即第二个sheet 其中第一个参数表示添加的位置在哪个sheet之前；第二个说在之后；第三个是要新建的工作表的数目，默认值为 1；第四个指定工作表类型，类型值可为：xlWorksheet、xlChart、xlExcel4MacroSheet 或 xlExcel4IntlMacroSheet。

//第一行的样式

Microsoft.Office.Interop.Excel.Range range1 = Sheet.get_Range(Sheet.Cells[1, 1], Sheet.Cells[1, column.Length]);//第一行
            //range1.Interior.ColorIndex = 15;//15代表灰色
            range1.Font.Bold = true; //字体加粗
            range1.Font.Size = 14;//字体大小
            range1.RowHeight = 20;//行高
            range1.MergeCells = true;//合并单元格
            range1.VerticalAlignment = XlVAlign.xlVAlignCenter;//上下居中
            range1.HorizontalAlignment = XlHAlign.xlHAlignCenter;//左右居中

同sheet1添加数据

//数据填充结束，要关闭excel对象
