C#使用NPOI实现导入导出Excel数据一、NPOI简介 1.1、NPOI是什么　　NPOI是POI的.NET版本,POI是一套用Java写成的库，我们在开发中经常用到导入导出表格、文档的情况，NPOI能够帮助我们在没有安装微软Office的情况下读写Office文件，如xls, doc, ppt等。NPOI采用的是Apache 2.0许可证（poi也是采用这个许可证），这意味着它可以被用于任何商业或非商业项目，我们不用担心因为使用它而必须开放你自己的源代码，所以它对于很多从事业务系统开发的公司来说绝对是很不错的选择。 1.2、NPOI简阅读详情

引用Microsoft.Office.Interop.Excel出现的问题

08-06-11 14:41 View:1022


操作背景:asp.net操作Excel

出现问题:在本地添加引用(com):Microsoft Office 11.0 Object Library,并写好程序调试正常,部署到服务器时,出现异常 Excel.Application不是对象.

初步诊断:服务器没有安装Excel组件

第一步尝试解决:对服务器安装Excel等Office组件,进一步测试程序:失败!

第二步尝试解决:将Excel.exe生成Interop.Excel.dll,然后用sdk引用该Dll,编译成功,测试程序:成功!

原因:本地引用的com不会在程序的bin目录生成dll文件,而程序是根据路径在寻找dll的.部署到服务器上时,假如Excel等dll与本地路径不一致,将会抛出异常,定义的Excel对象肯定是不存在的.

具体方法:

1、如何生成Interop.Excel.dll？

进入你的visual studio的sdk下的bin目录，找到TlbImp.exe文件，如果没有，请用光盘安装此文件，详细说明请参照MSDN。
命令行(cmd)进入bin目录，运行TlbImp /out:Interop.Excel.dll Office安装目录+Excel.exe

此时很可能会报错：TlbImp error: Unable to locate input type library: 'c:/program files/mcrosoft offi
ce/office/EXCEL.EXE'
此问题很有可能是TlbImp的bug，不支持空格式的路径；（具体原因不明）不要紧，将Excel.exe拷贝入bin目录，直接运行TlbImp /out:Interop.Excel.dll Excel.exe,提示“Type library imported to Interop.Excel.dll路径”

在bin目录下找到Interop.Excel.dll文件。在你的visual studio里将其引用即可。

2、如果是excel2000或excel2002怎么办？

如果是Excel2000，则将Excel.exe改成Excel9.olb
Excel2002同2003

3、各种版本的引用组件参数如下：

文件/版本	Interop.Excel.dll	Interop.Office.dll	Interop.VBIDE.dll	添加引用/COM组件
2000	V1.3.0.0	V2.1.0.0	V5.3.0.0	Microsoft Excel 9.0 Object Library(EXCEL9.OLB)
2002(XP)	V1.4.0.0	V2.2.0.0	V5.3.0.0	Microsoft Excel 10.0 Object Library(Excel.EXE文件)
2003	V1.5.0.0	V2.3.0.0	V5.3.0.0	Microsoft Excel 11.0 Object Library(Excel.EXE文件)

在office的安装目录内找到那个文件就可以了
，我找到的是Microsoft.Office.Interop.Excel.dll文件，拷到程序目录就OK。
