Answer 1

VB.Net'in Generics'i, bildirilebilir sınırlı denetimler oluşturmak için nasıl kullanılır.

Class MainWindow 

Public Sub New() 

    InitializeComponent() 

    Me.DataContext = Me 

End Sub 

Public Property NoNotify As String = "No notify" 
Public Property DoesNotify As New NotifiableProperty(Of String)("DoesNotify") 

Private Sub TestBtn_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles TestBtn.Click 
    NoNotify = "Won't Show" 
    DoesNotify.Value = "Notified!" 
End Sub 

End Class 

Public Class NotifiableProperty(Of T) 
    Implements System.ComponentModel.INotifyPropertyChanged 
Sub New() 
End Sub 
Sub New(ByVal InitialValue As T) 
    value = InitialValue 
End Sub 
Private m_Value As T 
Public Property Value As T 
    Get 
     Return m_Value 
    End Get 
    Set(ByVal value As T) 
     m_Value = value 
     RaiseEvent PropertyChanged(Me, New System.ComponentModel.PropertyChangedEventArgs("Value")) 
    End Set 
End Property 
    Private Event PropertyChanged(ByVal sender As Object, ByVal e As System.ComponentModel.PropertyChangedEventArgs) Implements System.ComponentModel.INotifyPropertyChanged.PropertyChanged 
End Class
