EDIT: I'd better rephrase: How can I shift the GET-implementation of a Class property to a / using a custom attribute? (I've added instantation vars (classname, propertyname) to the attribute, however I'd rather have these automatically fetched ofcourse.)

Public Class CustomClass
    <CustomAttributeClass(ClassName:="CustomClass", PropertyName = "SomeProperty")> _
    Public Property SomeProperty() as String
        Get() as String
            //This implementation should be handled by the attribute class
        End Get

        Set(Byval value as String)
            Me._someProperty = value
        End Set
    End Property
End Class

Old question:

I want to create a custom property attribute for classes. I can create a class derived from Attribute, and 'mark' the property with the attribute, but where to go from here?

I have a repository where I can quickly get data based on the attributes values. I would like to generalize the behaviour of the property in the attribute but I don't know how to go from here... Any help would be greatly accepted!

Public Class CustomDataAttribute : Inherits Attribute
    Private _name As String

    Public Sub New(ByVal name As String)
        Me.Name = name
    End Sub

    Property Name() As String
        Get
            Return _name
        End Get
        Set(ByVal value As String)
            Me._name = value
        End Set
    End Property
End Class


Public Class CustomClass
    <CustomDataAttribute(Name:="CustomField")> _ 
    Public Property CustomField()
    End Property
End Class
