RT/Metro商店应用如何调用SQLite数据库

async void Create() { // 数据文件保存的位置 var dbPath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, " db1.sqlite " ); // 打开创建数据库和表 using ( var db = new SQLite.SQLiteConnection(dbPath)) { // 创建表 var result = db.CreateTable<Model.Person> (); await new MessageDialog( " 返回值: " + result).ShowAsync(); } } private async void Insert() { // 连接数据库 var dbPath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, " db1.sqlite " ); using ( var db = new SQLite.SQLiteConnection(dbPath)) { // 插入操作。首先声明一个集合 ObservableCollection<Person> Collection = new ObservableCollection<Person> (); // 单条插入语句 db.Insert( new Person() { FirstName = " 宋兴柱1 " , LastName = " Sindrol " }); Collection.Add( new Person() { FirstName = " 宋兴柱2 " , LastName = " Sindrol1 " }); Collection.Add( new Person() { FirstName = " 宋兴柱3 " , LastName = " Sindrol2 " }); // 多条插入集合 var result = db.InsertAll(Collection); await new MessageDialog( " 返回值: " + result).ShowAsync(); } } private async void Update() { // 更新语句 var dbPath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, " db1.sqlite " ); using ( var db = new SQLite.SQLiteConnection(dbPath)) { SQLiteCommand cmd = db.CreateCommand( " update person set FirstName=‘lisa‘ where LastName=‘Sindrol‘ " ); var result = cmd.ExecuteNonQuery(); await new MessageDialog( " 返回值: " + result).ShowAsync(); } } private async void Delete() { var dbPath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, " db1.sqlite " ); using ( var db = new SQLite.SQLiteConnection(dbPath)) { // 单行删除操作 db.Delete<Person>( 1 ); // 多行删除 var result = db.DeleteAll<Person> (); await new MessageDialog( " 返回值: " + result).ShowAsync(); } } private async void Select() { var dbPath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, " db1.sqlite " ); using ( var db = new SQLite.SQLiteConnection(dbPath)) { // 查询所有数据绑定到UI List< object > list = db.Query( new TableMapping( typeof (Person)), " select * from Person " ); gridView.ItemsSource = list; } }

Person类如下图所示:

   class   Person
    {

        [SQLite.AutoIncrement, SQLite.PrimaryKey]
          public   int  ID {  get ;  set  ; }
          public   string  FirstName {  get ;  set  ; }
          public   string  LastName {  get ;  set  ; }
    }
