.net + firebird实现内置数据库的桌面程序

1. 下载firebird http://www.firebirdsql.org/en/server-packages/笔者选的是2.5.2
2.  解压，进入bin目录，install_super.bat
3.  我的电脑右键->管理->服务，将firebird的服务置成手动
4.  可选，下载一个firebird的client，笔者选的是FlameRobin还挺好用的
至此，可以试试firebird了，可以使用firebird/bin/isql,
CREATE DATABASE 'firstdb.gdb' USER 'sysdba' PASSWORD 'masterkey';
然后使用客户端去操作一下，比较标准的sql语言
5.  下载.net的连接firebird的库， .net provider http://www.firebirdsql.org/en/net-provider/,请注意与你工程的.net版本匹配.
6.   将dll引用到工程中，右键点击右侧引用，添加...
