先下载ADO.NET2.0 Provider for SQLite。下载binaries zip版就可以了。下载完后解压缩，可以在bin目录下找到System.Data.SQLite.DLL。在vs2008中用Add Reference功能把System.Data.SQLite.DLL加到工程里就可以了。运行下面代码试试： string datasource = "e:/tmp/test.db"; System.Data.SQLite.SQLiteConnection.CreateFile(datasource); //连接数据库 System.Data.SQLite.SQLiteConnection conn = new System.Data.SQLite.SQLiteConnection(); System.Data.SQLite.SQLiteConnectionStringBuilder connstr = new System.Data.SQLite.SQLiteConnectionStringBuilder(); connstr.DataSource = datasource; connstr.Password = "admin";//设置密码，SQLite ADO.NET实现了数据库密码保护 conn.ConnectionString = connstr.ToString(); conn.Open(); //创建表 System.Data.SQLite.SQLiteCommand cmd = new System.Data.SQLite.SQLiteCommand(); string sql = "CREATE TABLE test(username varchar(20),password varchar(20))"; cmd.CommandText = sql; cmd.Connection = conn; cmd.ExecuteNonQuery(); //插入数据 sql = "INSERT INTO test VALUES('a','b')"; cmd.CommandText = sql; cmd.ExecuteNonQuery(); //取出数据 sql = "SELECT * FROM test"; cmd.CommandText = sql; System.Data.SQLite.SQLiteDataReader reader = cmd.ExecuteReader(); StringBuilder sb = new StringBuilder(); while (reader.Read()) { sb.Append("username:").Append(reader.GetString(0)).Append("\n") .Append("password:").Append(reader.GetString(1)); } MessageBox.Show(sb.ToString());
