  In the code below, I am trying to create a collection of "SomeClass" objects, each one being created based on the generic type chosen by the caller of "CreateSomeList", like this:

  Dim c as Collection = CreateSomeList(GetType(Integer), GetType(Single), GetType(Double), GetType(Date)) 

  The problem is that the line "Dim sc as SomeClass(Of t)" fails to compile, saying "Type 't' is not defined.".

  Here is the complete code to reproduce:

  Public Function CreateSomeList(ByVal ParamArray Types() As System.Type) As Collection

  Dim somelist As New Collection For Each t As System.Type In Types
      Dim sc As SomeClass(Of t) ' this is the line that fails to compile
      somelist.Add(sc)
  Next

  Return somelist
  End Function

  Public Class SomeClass(Of T)
  Private mValue As T
  Public Property Value() As T
      Get
          Return mValue
      End Get
      Set(ByVal value As T)
          mValue = value
      End Set
  End Property

  End Class

  How can I make this work?
