I am writing a function that replaces tokens in a string with property
values of a given object. from each token I get a property name and using
reflection, I get the value of the property. Some properties are generic
lists, I can tell what is the type of the generic in the list
(PropertyValue.GetType.GetGenericArguments)
How can I cast the value returned by the InvokeMember call to the right
generic type?

in this sample "ClaimManagerItem" is a base class, GenericType will always
be of class inheriting from the base class

PropertyValue = SourceType.InvokeMember(PropertyName, Flags, Nothing,
Source, Nothing)
If PropertyValue.GetType.GetGenericArguments.Length <> 0 Then 'Generic

Dim GenericType As Type = PropertyValue.GetType.GetGenericArguments(0)

For Each CMItem As ClaimManagerItem In DirectCast(PropertyValue,
GenericType(of ??? )

....

Thanks for the help
