Asp.net mvc3 syntax syntax for translating a model into its subclass by reflection

I have a very simple question that I cannot find the answer to. In razor mode there is an interface model. This interface has several subclasses that implement it. The question arises: how can I apply a model to its actual type? I MUST have a variable of the actual type, but I don’t know how to get it from reflection That is.

@model IInterface
@{
   var actualType1 = Model as Model.GetType(); // doesn't work :(
   var actualType2 = (Model.GetType()) Model; // doesn't work :(
}

As you can imagine, I am not interested in Model as ActualTypeor (ActualType) Modelbecause I do not know which actual type comes in advance. His question is about technology, not about architecture.

Thanks in advance!
