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; }
    }
