Mapping multiple columns to an array with NHibernate

Question

I have an old database which can't be changed and I am currently using NHibernate.
The problem is that I have a table with multiple columns and I would like to map them into a single array.

Table ID
Price1
Price2
Price3
Price4
[...]

The class will be the following:

public class MyClass {
  public int Id { get; set; }
  public decimal[] Prices { get; set; }
}

Is it possible?
I must only read data and I don't actually need to set/save that property.
I have tried many mappings but I couldn't find an answer.

Answer 1

well, this is only a workaround, and is pretty dirty, but I think it might work:

public class MyClass {
  public virtual int Id { get; set; }
  protected virtual decimal Price1 { get; set; }  
  protected virtual decimal Price2 { get; set; }  
  protected virtual decimal Price3 { get; set; }  
//...
  public decimal[] Prices 
  { get 
    {
      return new decimal[] {Price1, Price2, Price3};
    }
  }
}

but, there might be a more sophisticated answer using NH's mapping abilities that I don't know of.
