inheritance

I have a C# .NET 2.0 project A that has a form (TreeForm) that uses Tree objects.

I have a project B that has a class Oak that inherits Tree.

When I try to reference and use the TreeForm in project B with my Oak objects, it's looking for objects of type Tree.

I've tried casting the Oak objects to Tree, but I get the error "Cannot convert type Oak to Tree".

How can I use my Oak objects in the TreeForm from project A?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
