The following example defines a control named MyControl. The class is marked with a DefaultPropertyAttribute that specifies MyProperty as the default property.
The next example creates an instance of MyControl. Then it gets the attributes for the class, extracts the DefaultPropertyAttribute, and prints the name of the default property.
Public Shared Function Main() As Integer ' Creates a new control. Dim myNewControl As New MyControl() ' Gets the attributes for the collection. Dim attributes As AttributeCollection = TypeDescriptor.GetAttributes(myNewControl) ' Prints the name of the default property by retrieving the ' DefaultPropertyAttribute from the AttributeCollection. Dim myAttribute As DefaultPropertyAttribute = _ CType(attributes(GetType(DefaultPropertyAttribute)), DefaultPropertyAttribute) Console.WriteLine(("The default property is: " + myAttribute.Name)) Return 0 End Function 'Main
