将ObservableCollection<MyClass>保存为SQLite或类似的Xamarin表单

public class MyClass
{
    [PrimaryKey, AutoIncrement]
    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
    // 其他属性...
}

public class DatabaseContext : SQLiteConnection
{
    public DatabaseContext(string databasePath) : base(databasePath)
    {
        CreateTable<MyClass>();
    }

    public TableQuery<MyClass> MyClasses => Table<MyClass>();
}

var myClasses = new ObservableCollection<MyClass>();
// 添加数据到myClasses...

var databasePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "database.db");
using (var db = new DatabaseContext(databasePath))
{
    db.InsertAll(myClasses.ToList());
}

var databasePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "database.db");
using (var db = new DatabaseContext(databasePath))
{
    var myClasses = new ObservableCollection<MyClass>(db.MyClasses.ToList());
    // 使用myClasses中的数据...
}
