[转]C#与SQLite的操作介绍
1、通过Add References引用SQLite ADO .NET安装目录的bin目录下的System.Data.SQLite.DLL。2、创建数据库文件：因为始终是个0字节文件，应该利用IO也可以（？！）。
System.Data.SQLite.SQLiteConnection.CreateFile(datasource);
3、连接数据库
System.Data.SQLite.SQLiteConnection conn = new System.Data.SQLite.SQLiteConnection(connectionString);
connectionString中包含了数据库的一些配置信息，比如数据库文件，数据库打开的密码等，可以利用System.Data.SQLite.SQLiteConnectionStringBuilder来辅助创建connectionString
4、创建表、读取数据等和Access或MS SQL没多大区别了。
