.NET中操作SQLite

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");

     //默认生成的数据库文件和System.Data.SQLite.dll在同一路径下

        }

        //创建一个连接到指定数据库
        void connectToDatabase()
        {
            m_dbConnection = new SQLiteConnection("Data Source=MyDatabase;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();
        }
    }
}
