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

  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

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)

image

重新编译,安装OK
