中小企业办公自动化系统都需要有与微软办公软件连接的功能，如把数据导入到电子表格、Word等功能。C#.NET在Office方面提供了强大的功能，只要导入 Microsoft.Office.Interop.Excel 命名空间并调用此命名空间下的类，就可以在程序调用Excel、Word。

  （一）Excel开发

   首先导入 Microsoft.Office.Interop.Excel 命名空间

   需要的类

   _Application excel = new ApplicationClass();  //实例化对象

   int rowIndex = 6;
   int colIndex = 0;

   _Workbook xBk;
   _Worksheet xSt;

   xBk = excel.Workbooks.Add(true);
   xSt = (Microsoft.Office.Interop.Excel._Worksheet)xBk.ActiveSheet;

   //取得列标题
   for (int i = 0; i < dgvYingShouAmount.Columns.Count; i++){
      colIndex++;
      excel.Cells[rowIndex, colIndex] = Convert.ToString(dgvYingShouAmount.Columns[i].HeaderText);
   }

   //取得表格中的数据

   for (int i = 0; i < dgvYingShouAmount.Rows.Count; i++){
      rowIndex++;
      colIndex = 0;
      for (int j = 0; j < dgvYingShouAmount.Columns.Count; j++){
         colIndex++;

         excel.Cells[rowIndex, colIndex] =Convert.ToString(dgvYingShouAmount.Rows[i].Cells[j].Value);
         xSt.get_Range(excel.Cells[rowIndex, colIndex], excel.Cells[rowIndex, colIndex]).HorizontalAlignment = XlHAlign.xlHAlignCenter;
      }     
   }

    excel.Cells[1, 1] = "***有限公司";
    excel.Cells[2, 1] = "地址";
    excel.Cells[3, 1] = "电话 传真";
    excel.Cells[4, 1] = "客户对账单";
    excel.Cells[5, 1] = "操作日期：" + dtpStartDate.Value.ToString("yyyy-MM-dd") + "/" + dtpEndDate.Value.ToString("yyyy-MM-dd");

    // 
    //设置整个报表的标题格式 
    // 
    xSt.get_Range(excel.Cells[1, 1], excel.Cells[1, 1]).Font.Bold = true;
    xSt.get_Range(excel.Cells[1, 1], excel.Cells[1, 1]).Font.Size = 22;

    xSt.get_Range(excel.Cells[3, 1], excel.Cells[3, 1]).Font.Bold = true;

    //设置报表表格为最适应宽度 
    // 
    xSt.get_Range(excel.Cells[6, 2], excel.Cells[rowIndex, colIndex]).Select();
    xSt.get_Range(excel.Cells[6, 2], excel.Cells[rowIndex, colIndex]).Columns.AutoFit();

    //设置整个报表的标题为跨列居中 
    // 
    xSt.get_Range(excel.Cells[1, 1], excel.Cells[1, colIndex]).Select();
    xSt.get_Range(excel.Cells[1, 1], excel.Cells[1, colIndex]).HorizontalAlignment = XlHAlign.xlHAlignCenterAcrossSelection;
    xSt.get_Range(excel.Cells[2, 1], excel.Cells[2, colIndex]).Select();
    xSt.get_Range(excel.Cells[2, 1], excel.Cells[2, colIndex]).HorizontalAlignment = XlHAlign.xlHAlignCenterAcrossSelection;
    xSt.get_Range(excel.Cells[3, 1], excel.Cells[3, colIndex]).Select();
    xSt.get_Range(excel.Cells[3, 1], excel.Cells[3, colIndex]).HorizontalAlignment = XlHAlign.xlHAlignCenterAcrossSelection;
    xSt.get_Range(excel.Cells[4, 1], excel.Cells[4, colIndex]).Select();
    xSt.get_Range(excel.Cells[4, 1], excel.Cells[4, colIndex]).HorizontalAlignment = XlHAlign.xlHAlignCenterAcrossSelection;
    xSt.get_Range(excel.Cells[5, 1], excel.Cells[5, colIndex]).Select();
    xSt.get_Range(excel.Cells[5, 1], excel.Cells[5, colIndex]).HorizontalAlignment = XlHAlign.xlHAlignCenterAcrossSelection;
    // 
    //绘制边框 
    // 
    xSt.get_Range(excel.Cells[6, 1], excel.Cells[rowIndex, colIndex]).Borders.LineStyle = 1;
    xSt.get_Range(excel.Cells[6, 1], excel.Cells[rowIndex, colIndex]).Borders[Microsoft.Office.Interop.Excel.XlBordersIndex.xlEdgeLeft].Weight = Microsoft.Office.Interop.Excel.XlBorderWeight.xlThick;//设置左边线加粗 
    xSt.get_Range(excel.Cells[6, 1], excel.Cells[rowIndex, colIndex]).Borders[Microsoft.Office.Interop.Excel.XlBordersIndex.xlEdgeTop].Weight = Microsoft.Office.Interop.Excel.XlBorderWeight.xlThick;//设置上边线加粗 
    xSt.get_Range(excel.Cells[6, 1], excel.Cells[rowIndex, colIndex]).Borders[Microsoft.Office.Interop.Excel.XlBordersIndex.xlEdgeRight].Weight = Microsoft.Office.Interop.Excel.XlBorderWeight.xlThick;//设置右边线加粗 
    xSt.get_Range(excel.Cells[6, 1], excel.Cells[rowIndex, colIndex]).Borders[Microsoft.Office.Interop.Excel.XlBordersIndex.xlEdgeBottom].Weight = Microsoft.Office.Interop.Excel.XlBorderWeight.xlThick;//设置下边线加粗

    excel.Visible = true;

    string file = "保存的路径";
    xBk.SaveCopyAs(file);
