How do you set a model with repeating variables?

问题

Objective: Use the model to show total sales of an id and total sales difference for multiple periods.

Issue: Using MVC4 I have a model for a report that displays total sales. I know I can add a variable for each additional period, but I have many periods that I'd like to use to compare and show a difference. How can this be done avoiding needless repetition?

public class Report
{
     public long ID { get; set }

    public long TotalSales { get; set}

    public long TotalSales2 { get; set}

    public long TotalSalesDiff { get; set} 

 }

Thank you in advance for any suggestions and/or comments

If I understood your scenario you have two option either create a dictionary that can create properties or use Dynamic object class

For dictionary

 public class DictionaryProperty
 {

      Dictionary<string, object> Yourproperties = new Dictionary<string, object>( );

      public object this[ string name ]
      {
            get
            {
                 if ( Yourproperties.ContainsKey( name ) )
                 {
                      return Yourproperties[ name ];
                 }
                 return null;
            }
            set
            {
                 Yourproperties[ name ] = value;
            }
      }

 }

}

And for the Dynamic object please refer following link http://msdn.microsoft.com/en-us/library/system.dynamic.dynamicobject.aspx
