Reflection???

[Guest]

I pass an array that consists of elements each of an unknown class to a
function. I want to get a list of the properties of the unknown class and
the value for each property for each element of the array. How would I do
this. I tried propertyDescriptionclass but got an error saying I needed to
use late binding.

Something like this:

Dim obj As Object = myArray(1)

For Each pi As PropertyInfo In obj.GetType.GetProperties( _
BindingFlags.Public Or BindingFlags.NonPublic _
Or BindingFlags.Instance)
Console.WriteLine(pi.Name)
Console.WriteLine(pi.GetValue(obj, Nothing).ToString)
Next

This will give you both public and non-public properties. If you only want
the public properties, you can use the overloaded version of GetProperties
without any arguments.

hope that helps..

hmmm... Here is a rough translation of some code from a debuging class
I wrote that does that (the original is C#, so forgive any little syntax
errors

Option Strict On
Option Explicit On

Imports System.Reflection

Dim theType As Type = theObject.GetType ()
Dim properties() As PropertyInfo = theType.GetProperties ()

For Each prop As PropertyInfo in properties
Try
Console.WriteLine ("{0} = {1}", _
prop.Name, prop.GetValue (theObject, Nothing))
Catch
End Try
Next prop
