创建一个WPF的ObservableCollection从亚音速2.2收藏(Create A WPF

如果我有亚音速2.2中创建一个DAL，我怎么通过转换可以在代码中创建的WPF ObservableCollections的集合（pref.VB.NET）将通过WPF消耗？

Answer 1:

对不起VB！

[Test]
public void Exec_Testing()
{
    ProductCollection products =
        DB.Select().From("Products")
            .Where("categoryID").IsEqualTo(5)
            .And("productid").IsGreaterThan(50)
            .ExecuteAsCollection<ProductCollection>();

    Assert.IsTrue(products.Count == 77);

    ObservableCollection<Product> obsProducts = new ObservableCollection<Product>(products);
}

Answer 2:

您必须手动添加到您的DAL类，但它不是太难。 在每一个数据访问层类的顶部，加上“实现INotifyPropertyChanged”，然后在每个属性，在“设置”就像你看到下面的代码添加。

Private _Book As String
Public Property Book() As String
    Get
        Return _Book
    End Get
    Set(ByVal value As String)
        If Not _Book = value Then
            _Book = value
            ' Raise the property changed event.
            RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs("Book"))
        End If
    End Set
End Property 

Public Event PropertyChanged(ByVal sender As Object, ByVal e As System.ComponentModel.PropertyChangedEventArgs) Implements System.ComponentModel.INotifyPropertyChanged.PropertyChanged
