SQLite介绍
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:
C#使用SQLite步骤:
(1)新建一个project
(2)添加SQLite操作驱动dll引用
(3)使用API操作SQLite DataBase
using System;using System.Data.SQLite;namespace SQLiteSamples{ class Program { //数据库连接 SQLiteConnection m_dbConnection; static void Main(string[] args) { Program p = new Program(); } public Program() { createNewDatabase(); connectToDatabase(); createTable(); fillTable(); printHighscores(); } //创建一个空的数据库 void createNewDatabase() { SQLiteConnection.CreateFile("MyDatabase.sqlite"); } //创建一个连接到指定数据库 void connectToDatabase() { m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;"); m_dbConnection.Open(); } //在指定数据库中创建一个table void createTable() { string sql = "create table highscores (name varchar(20), score int)"; SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection); command.ExecuteNonQuery(); } //插入一些数据 void fillTable() { string sql = "insert into highscores (name, score) values ('Me', 3000)"; SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection); command.ExecuteNonQuery(); sql = "insert into highscores (name, score) values ('Myself', 6000)"; command = new SQLiteCommand(sql, m_dbConnection); command.ExecuteNonQuery(); sql = "insert into highscores (name, score) values ('And I', 9001)"; command = new SQLiteCommand(sql, m_dbConnection); command.ExecuteNonQuery(); } //使用sql查询语句,并显示结果 void printHighscores() { string sql = "select * from highscores order by score desc"; SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection); SQLiteDataReader reader = command.ExecuteReader(); while (reader.Read()) Console.WriteLine("Name: " + reader["name"] + "\tScore: " + reader["score"]); Console.ReadLine(); } }}
