C#使用Aspose.Cells导出Excel简单实现

首先，需要添加引用Aspose.Cells.dll，官网下载地址：http://downloads.aspose.com/cells/net

将DataTable导出Xlsx格式的文件下载（网页输出）：

 /// <summary>
 /// 导出Excel表格
 /// </summary>
 /// <param name="list">数据集合</param>
 /// <param name="header">数据表头</param>
 /// <returns></returns>
 public void ExportExcel(DataTable dt, string[] header)
 {
     Workbook wb = new Workbook(FileFormatType.Xlsx);
     try
     {
         Worksheet sheet = wb.Worksheets[];
         sheet.Name = "MO上行查询结果";
         if (dt.Rows.Count <= )
         {
             System.Web.HttpContext.Current.Response.Write("<script>alert('没有检测到需要导出数据!');</script>");
             return;
         }
         // 为单元格添加样式
         Aspose.Cells.Style style = wb.CreateStyle();
         style.HorizontalAlignment = Aspose.Cells.TextAlignmentType.Center;  //设置居中
         style.Font.Size = ;//文字大小
         style.Font.IsBold = true;//粗体
         style.HorizontalAlignment = TextAlignmentType.Center;//文字居中

         int rowIndex = ;
         for (int i = ; i < header.Length; i++)
         {
             sheet.Cells[rowIndex, i].PutValue(header[i]);
             sheet.Cells[rowIndex, i].SetStyle(style);
             sheet.Cells.SetColumnWidth(i, );//设置宽度
         }
         for (int i = ; i < dt.Rows.Count; i++)//遍历DataTable行
         {
             sheet.Cells[i + , ].PutValue(dt.Rows[i]["SENDER"].ToString());
             sheet.Cells[i + , ].PutValue(dt.Rows[i]["SENDCONTENT"].ToString());
             sheet.Cells[i + , ].PutValue("");
             sheet.Cells[i + , ].PutValue(dt.Rows[i]["RECDATE"].ToString());
             sheet.Cells[i + , ].PutValue(dt.Rows[i]["sn"].ToString());
         }
     }
     catch (Exception e)
     {
         System.Web.HttpContext.Current.Response.Write("<script>alert('导出异常:" + e.Message + "!');</script>");
     }
     #region 输出到Excel
     using (MemoryStream ms = new MemoryStream())
     {

         wb.Save(ms, new OoxmlSaveOptions(SaveFormat.Xlsx));//默认支持xls版，需要修改指定版本
         System.Web.HttpContext.Current.Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}.xlsx", DateTime.Now.ToString("yyyyMMddHHmmssfff")));
         System.Web.HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
         System.Web.HttpContext.Current.Response.BinaryWrite(ms.ToArray());
         wb = null;
         System.Web.HttpContext.Current.Response.End();
     }
     #endregion
 }
