LINQ converting to a list or array to pass to another method.

Hi

I have a datatable of data. I want to convert a subset and sepecific columns of the table data to a class object to pass to another method for analysis. I am trying to convert to a list to pass. Assistance to advise how to would be appreciated, either a smarter way or how to make this way work.

Class as follows
public class clsData
        {
            public decimal Back;
            public decimal Mean;
        }

Have data in a table, and trying to use LINQ to create a list (or array) to pass to a method as can't pass a VAR object.

   var PastData = (from c in results
                                       select new
                                       {
                                           Back = c.Field<decimal>("Price"),
                                           QMean = c.Field<decimal>("QMean")                                        
                                       }).ToList();
Have tried to cast to the ClsData object without success. Then would want to receiveit in the method with something like

Public void List<ClsData> cd
{
}

Any advice would be appreciated
