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

1. 做成安装包（自定义安装，用数据库备份文件还原）
2. 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：

1. 找到数据库备份文件
2. 安装时还原数据库
3. 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

重新编译，安装OK
