Reflection and PropertyInfo

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().Ge tProperties(Ref lection.Binding Flags.Instance Or
Reflection.Bind ingFlags.NonPub lic)

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,

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.GetField s
(BindingFlags.I nstance Or BindingFlags.No nPublic)

For Each field As FieldInfo In fields

If field.FieldType .Name = "MenuItem" Then
Dim menu As MenuItem = DirectCast(fiel d.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.W ebControl
and these objects easily can be retrieved using the Controls collection.
And, yes, I'm new to Visual Basic .NET...

ey all, I'm in the process of creating a method of tracking whenever an objects properties are changed. Since its not possible to alter existing types I decided to used a proxy generated using Reflection.Emit which inherits from the object needed Person p = (Person)ProxyBuilder.Construct(typeof(Person));

Hi everybody, I've run into a problem when using the reflection assembly on COM objects and been browsing around the net for some while. Apparently a few has asked the same question though no answer has ever occoured. This is what I'm trying to do: I wish to build a function that crawls any COM object (interop). I did shortly examine the serializer until I realized it's used for translation

Hi, I have an old problem which I couldn't solve so far. Now I have found a post in that group that gave me an idea, but I can not fully understand it. The problem is: I'm trying to use a Windows.Forms.UserControl in a COM environment, i.e. I want to host that control in a COM host. So far, so good, I can host it, but I can not reach the parent COM object from the control (Parent property is null :( ). I have stopped the control in the...

Hey, I'm attempting to use reflection in order to get the types of properties in a class. However, I seem to be having trouble determining exactly which type I am getting. In the foreach of running through the properties, the PropertyInfo.Name does cycle through all the properties, however, if you check the PropertyInfo.GetType().ToString() it is always "System.Reflection.PropertyInfo". Which technically makes sense. What doesnt...

Given a class 'Invoice' with a property 'public IMyColl<IInvoiceLine> InvoiceLines' where 'IMyColl<T> : IList<T>' i would like to detect by reflection that 'InvoiceLines' is a 'System.Collection.Generic.IList'. When performing something like: 'if (typeof(IList<>).IsAssignableFrom(propertyInfo.Type))' where 'propertyInfo' obviously refers to the 'InvoiceLines', the result is always 'false' because indeed 'IList<object>' and...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
