How to iterate through each property of a custom vb.net object?

Question

How can I go through each of the properties in my custom object? It is not a collection object, but is there something like this for non-collection objects?

For Each entry as String in myObject     ' Do stuff here... Next 

There are string, integer and boolean properties in my object.

Answer 1

By using reflection you can do that. In C# it looks like that;

PropertyInfo[] propertyInfo = myobject.GetType().GetProperties(); 

---

Added a VB.Net translation:

Dim info() As PropertyInfo = myobject.GetType().GetProperties() 

Answer 2

You can use System.Reflection namespace to query information about the object type.

For Each p As System.Reflection.PropertyInfo In obj.GetType().GetProperties()    If p.CanRead Then        Console.WriteLine("{0}: {1}", p.Name, p.GetValue(obj, Nothing))    End If Next 

Please note that it is not suggested to use this approach instead of collections in your code. Reflection is a performance intensive thing and should be used wisely.
