本文實例分析了C# SQlite操作方法。分享給大家供大家參考，具體如下：
最近項目需求用C#保存一些數據，如此先總結一下。需要下載Sqlite 庫 SourceForge 鏈接網址http://sourceforge.net/projects/sqlite-dotnet2/或到官方網http://www.sqlite.org/download.html下載都可以，下載之后安裝。在C#項目中添加引用 引入安裝目錄bin中的System.Data.SQLite.dll。添加命名空間using System.Data.SQLite;便可以在你的項目中
對擴平臺的微型數據庫SQlite 進行使用了，
主要注意一點是：
數據庫若未創建則使用：
SQLiteConnection.CreateFile(databaseName);
數據庫已經創建，并要進行訪問：
using System;using System.Collections.Generic;using System.Text;using System.Data.SQLite;namespace Toolbar{ public class CSPDatabase { protected string m_dbName; protected string m_tablename; protected string m_password; public CSPDatabase(string dbName) { m_dbName = dbName; m_tablename = "MhtInfo"; m_password = ""; } //Create DataBase public virtual void Init() { } public virtual void CreateDataBase() { } public virtual void OpenDataBase() { } public virtual void SetPassWord(string password) { } //Connect DataBase public virtual void ConnectDataBase() { } //Create Table public virtual void CreateTable(string tableName) { } //Insert Data public virtual void Insert(string mhtlocation) { } }}using System;using System.Collections.Generic;using System.Text;using System.Data.SQLite;using System.Windows.Forms;namespace Toolbar{ class SqliteDatabase : CSPDatabase { private SQLiteConnection m_conn= null; private SQLiteCommand m_cmd=null; public SqliteDatabase(string dbName):base(dbName) { } public override void Init() { if(m_conn == null) m_conn = new SQLiteConnection(); m_cmd = new SQLiteCommand(); m_cmd.Connection = m_conn; } public override void CreateDataBase() { //Create Database try { SQLiteConnection.CreateFile(m_dbName); Init(); ConnectDataBase(); } catch (System.Exception e) { MessageBox.Show("Create DataBase Failed!"); } } public override void OpenDataBase() { m_conn = new SQLiteConnection("Data Source="+m_dbName+";Version=3;New=False;Compress=True;"); Init(); ConnectDataBase(); } public override void SetPassWord(string password) { m_password = password; } public override void ConnectDataBase() { //Connect to DataBase try { SQLiteConnectionStringBuilder connstr = new SQLiteConnectionStringBuilder(); connstr.DataSource = m_dbName; if(m_password != "") connstr.Password = m_password; m_conn.ConnectionString = connstr.ToString(); } catch (System.Exception e) { MessageBox.Show("Fail to Connect to the database"); } } //Create Table public override void CreateTable(string tableName) { try { m_tablename = tableName; m_conn.Open(); string sql = "CREATE TABLE " + tableName + "(mhtlocation varchar(20))"; m_cmd.CommandText = sql; m_cmd.ExecuteNonQuery(); m_conn.Close(); } catch (System.Exception e) { MessageBox.Show("Create Table Failed!"); } } public override void Insert(string mhtlocation) { try { //Insert Data m_conn.Open(); string sql = "insert into [" + m_tablename + "] values('" + mhtlocation + "')"; m_cmd.CommandText = sql; m_cmd.ExecuteNonQuery(); m_conn.Close(); } catch (System.Exception e) { MessageBox.Show(e.ToString()); } } }}更多關于C#相關內容感興趣的讀者可查看本站專題：《C#程序設計之線程使用技巧總結》、《C#操作Excel技巧總結》、《C#中XML文件操作技巧匯總》、《C#常見控件用法教程》、《WinForm控件用法總結》、《C#數據結構與算法教程》、《C#數組操作技巧總結》及《C#面向對象程序設計入門教程》
