C# 'AS' Equivalent For Nullable Types

C#'s 'as' keyword will let you do this: int? input = value as int? Here's what I would assume the vb.net equivalent would be: Dim input As Integer? = TryCast(value, Integer?) There's an intellisense error in the TryCast stating the operand must be a reference type but Integer? is a value type.

Intellisense on Nullable(Of Integer) says 'Represents an object whose underlying type is a value type that can also be assigned null like a reference type.' It seems C#'s 'as' handles this like a reference type where TryCast doesn't have this built in. In VB10 I was able to take advantage of the new CTypeDynamic function to do the casting. Conversion.CTypeDynamic Method

Dim input As Integer? = CTypeDynamic(Of Integer?)(value)

Or:

Dim input As Integer? = CTypeDynamic(Value, GetType(Integer?))

There's a cost here as CTypeDynamic examines the type at runtime.

My question is what is the elegant way to handle this without CTypeDynamic?
