SQLite介绍
SQLite读[sk’laɪt]
SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine.
SQLite是一个开源、免费的小型RDBMS(关系型数据库),能独立运行、无服务器、零配置、支持事物,用C实现,内存占用较小,支持绝大数的SQL92标准。

C#操作SQLite Database
C#下SQLite操作驱动dll下载:System.Data.SQLite
C#使用SQLite步骤:
(1)新建一个project
(2)添加SQLite操作驱动System.Data.SQLite.dll引用
(3)使用API操作SQLite DataBase
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Data.SQLite; using System.IO; namespace SQLiteDemo1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { string datasource = Application.StartupPath + @"\test.db"; bool isExist = File.Exists(datasource); if (!isExist) { //创建数据库文件 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(); System.Data.SQLite.SQLiteCommand cmd = new System.Data.SQLite.SQLiteCommand(); cmd.Connection = conn; string sql = ""; if (!isExist) { //创建数据库文件 sql = "CREATE TABLE test(username varchar(20),password varchar(20))"; cmd.CommandText = sql; cmd.ExecuteNonQuery(); } //插入数据 sql = "INSERT INTO test VALUES('name_ludongbao','pwd_ludongbao')"; 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)).Append("\n"); } MessageBox.Show(sb.ToString()); } } }
