Casting Common Types

Public Function CastToT(Of T)(ByVal GenericType(Of Object) data) As GenericType(Of T)
   Return DirectCast(data, GenericType(Of T))
End Function

The above clearly doesn't work. Is there a way to do this selection when I know that all objects within the data are actually of type T?

This is not possible, except for interfaces.

No, you cannot use it directly. Presumably yours GenericType

is some sort of container. You just need to create a new instance GenericType(Of T)

and copy the content into it, discarding every object from Object

to T

. If you GenericType

had System.Collections.List(Of T)

, then LINQ makes it very easy.
