I am trying to use SilverlightPhoneDatabase to use a sqlite db for my Windows Phone 7 application.
The dll has a class Database
public class Database
{
.
.
.
public Table<T> Table<T>();
.
.
}
Definition of class Table is as follows:
public class Table<T> : ObservableCollection<T>开发者_开发百科, ITable
Then in my App.xaml I have a method
public static Database MyDB
{
get
{
// Delay creation of the view model until necessary
if (database == null)
OpenDatabase<MyObj>("MyObj");
return database;
}
}
Now from my xaml.cs file I am able to access the .ToList() method on the Table. ie If I say
App.MyDB.Table<MyObj>().ToList();
from my main.xaml.cs, I can access the ToList() method (Table class inherited from ObservableCollection..)
But I created a new class in a new cs in the same namespace.. and if I try to access the ToList() method on the Table class, I am getting compiler error that Table<> does not contain definition for 'ToList'
I am just curious why is it not working? It may be something silly I am missing.
ToList
is an extension method on IEnumerable<T>
: System.Linq.Enumerable.ToList
so you need to add an using for the System.Linq
namespace to be able to use it.
The compiler is basically rewriting
App.MyDB.Table<MyObj>().ToList();
as
System.Linq.Enumerable.ToList(App.MyDB.Table<MyObj>());
