【背景】
给别人写了个C#的exe，其中内部用到excel，然后自己C#项目中引用了：
Microsoft.Office.Interop.Excel
对应的version=14的：
C:\Program Files (x86)\Microsoft Visual Studio 10.0\Visual Studio Tools for Office\PIA\Office14\Microsoft.Office.Interop.Excel.dll
然后别人在其电脑上用exe，结果出错：

【解决过程】
1. 后来得知，别人机子上，已经安装了Microsoft Excel了。
所以，按理来说，应该可以找到Microsoft.Office.Interop.Excel.dll才对。
2.但是自己想起了之前的一个事情：
关于svn的脚本更新，以支持word等对比的，其中脚本配置中就有：
| C:\Program Files\TortoiseSVN\Diff-Scripts\diff-doc.js |
// Microsoft Office versions for Microsoft Windows OS var vOffice2000 = 9; var vOffice2002 = 10; var vOffice2003 = 11; var vOffice2007 = 12; var vOffice2010 = 14; var vOffice2013 = 15;
所以，应该是：
Office2007是Office12
Office2010是Office14
结果还出错，所以就推断出来，估计是他机子上的Office的版本低了，而我此处引用的版本高了：
即，别人电脑上的office是Office12，而我此处的是Office14
所以同样都是：
Microsoft.Office.Interop.Excel
但是却找不到此dll。
3.所以，此处去改为version=12的：
| C:\Program Files (x86)\Microsoft Visual Studio 10.0\Visual Studio Tools for Office\PIA\Office12\Microsoft.Office.Interop.Excel.dll |
引用：
然后的确就可以了。
4. 后来，为了，此处集成的dll，是内置集成的dll，所以，还是避免从vs安装目录中添加此office12的dll库，
而从自己当前项目，额外的添加自己的dll：
然后再设置为embedded：
【总结】
C#的exe用到了excel的话，希望拿到别人的地方也正常运行不报错的话，
其中，别的地方：
- 可能没装excel，
- 也可能装了excel，但是版本低
那么要：
1。最好自己在exe中集成了对应的excel的dll库。
关于，集成dll到exe中，
简述：
（1）把dll加到自己的资源resource中
（2）把dll加到自己的项目中，且属性设置为 嵌入的资源（Embedded Resource）
（3）自己的类的初始化函数中，加上对应的load dll的相关代码
详见：
或者是：
2. 即使不集成excel的dll，在引用excel的dll
（1）也要尽量引用低版本
比如别人已装的excel，即Office是Office12
那么你也就不要去引用Office14==Office2010：
| C:\Program Files (x86)\Microsoft Visual Studio 10.0\Visual Studio Tools for Office\PIA\Office14\Microsoft.Office.Interop.Excel.dll |
了，而去引用Office12==Office2007：
| C:\Program Files (x86)\Microsoft Visual Studio 10.0\Visual Studio Tools for Office\PIA\Office12\Microsoft.Office.Interop.Excel.dll |
（2）或者是和对方电脑中安装的excel的版本一致
当然，最好确认一下，对方的电脑中装了哪个版本的Office（的excel）
比如是Office 2010==Office14，那么你也就去引用对应的Office14：
| C:\Program Files (x86)\Microsoft Visual Studio 10.0\Visual Studio Tools for Office\PIA\Office14\Microsoft.Office.Interop.Excel.dll |
就好了。
