数据库安装文件制作（C#）
最近在做项目时，将软件打包给技术部门用，里面因为用到数据库，所以最好是在安装文件执行完毕之后，自动还原数据库（sql）
想到了2个方法
- 做成安装包（自定义安装，用数据库备份文件还原）
- 利用sql脚本，生成，但osql还是有限制
这2个方法都是可行的，第二个方法会出现多个文件，第一个方法只有一个安装包；
显然一个方法方便些；
实现思路：
- 找到数据库备份文件
- 安装时还原数据库
- 卸载时删除数据库
重写 public override void Install(IDictionary stateSaver)和public override void Uninstall(IDictionary savedState)方法
自己编写好代码，编译运行，安装，却出现1001错误，找不到数据库备份文件

网上有说，是customerAction路径问题,特在安装程序里面加MessageBox,来跟踪，发现木有问题。
幸好有网友说，资源要内嵌，特查找msnd，
将数据库备份文件更改下（右键数据库备份文件）
重新编译，安装OK
