Reflection and PropertyInfo

[Oskar Lundgren]

I want to iterate over fields declared like this, using reflection
(and there are good reasons for that):

Protected WithEvents Foo1 As Bar
Protected WithEvents Foo2 As Bar
....

I use the following code to get an array containing the fields
(wrapped in PropertyInfo objects):

Dim objs As Object() =
Me.GetType().GetProperties(Reflection.BindingFlags.Instance Or
Reflection.BindingFlags.NonPublic)

My question is: How do I get the wrapped "Bar" objects (Foo1, Foo2 and
so on)out of the PropertyInfo objects, so I can make calls to the
methods of the "Bar" objects. Using GetValue on the PropertyInfo
objects does not work.

Oskar,

Using GetValue on the PropertyInfo
objects does not work.

No? How does it fail?

Hello Oskar
See the following example its for MenuItem

<code>
Dim myForm As Type = f.GetType()

Dim fields As FieldInfo() = myForm.GetFields
(BindingFlags.Instance Or BindingFlags.NonPublic)

For Each field As FieldInfo In fields

If field.FieldType.Name = "MenuItem" Then
Dim menu As MenuItem = DirectCast(field.GetValue
(f), MenuItem)
'' you can use it here.
end if
next
</code>

Kind Regards
Jorge

The error message I get (at runtime):

Property Get method was not found

This does sound reasonable to me, since I haven't declared such a
method...

Anyway, I have found a solution of my problem. I didn't need to use
reflection, since the Bar class is a subclass System.Web.UI.WebControl
and these objects easily can be retrieved using the Controls collection.
And, yes, I'm new to Visual Basic .NET...
