关于导出excel报表,网上也是一搜一大把。整理一下,无非就是几种思路,有利用安装excel软件或插件的服务器直接生成,或者直接在客户端生成(通常都是利用excel软件或插件直接在浏览器生成)。反正万变不离其宗,离开excel插件,这个活你还真的干不了,由此你可以看到软件公司尤其是微软的强大。下面贴一个比较简单的导出excel报表的方法。在安装了office2003的机器上,通过ie浏览器可以成功生成excel,而且一直有人在使用。如果你在测试的时候发现这个根本无法使用,请注意,这个很可能和你的机器配置有关,别怀疑代码的正确性。下面就一个利用iBatis开发的例子来简单说明一下。
1、实体类
Code
using System;
using System.Collections.Generic;

using System.Web.UI;
using System.IO;
using System.Reflection;
#p#副标题#e#
namespace DotNet.Common.Util

///
/// 导出excel 简单实现
///
public static class ExcelUtil

private static Page currentPage = HttpContext.Current.Handler as Page;
private static Object sycObj = new Object();
private static int incremental = 10;
///
/// 按照时间生成excel名称 防止生成相同名的excel造成文件覆盖
///
///
private static string CreateExcelName()
{
lock (sycObj)
{
incremental = incremental + 1;
if (incremental > 99)
incremental = 10;
return Convert.ToInt64(DateTime.Now.ToString("yyyyMMddHHmmssfff") + incremental).ToString();
}
}
///
/// 导出excel
///
///
///
/// 要显示的列名
/// 要显示的导出属性名 和实体的属性名有关,顺序由显示的列确定 可以同listColumes
/// 实体集合
public static void ExportExcel
{
if (listColumns.Count == 0)
{
throw new IndexOutOfRangeException("No Columnes!");
}
if (listColumns.Count != listProperty.Count)
{
throw new ArgumentException("Columns and properties length are not equal.");
}
string sheetName = "sheetName";
using (StringWriter writer = new StringWriter())
{
writer.WriteLine("");
writer.WriteLine("
");writer.WriteLine("");
writer.WriteLine("");
writer.WriteLine("
");writer.WriteLine("
" + item + " | "); //列名
