I don't think you can do this (at least not simply) if the query uses an anonymous type. You could use a concrete type instead. Something like:

public class result
    {
        public result(string s)
        {
            Rep = s;
        }
        public string Rep { get; set; }
    }

then (simpler example):

var queryRep = from rows in dt.AsEnumerable() select new result(rows.Field<string>("Name"))
;
MyMethod(queryRep);

This should enable you for example to call:

void MyMethod(System.Data.EnumerableRowCollection result query)
        {
           foreach (result r in query)
           {
               Console.WriteLine(r.Rep);
           }
        }

Note: the angle brackets around the 'result' in the MyMethod parameters don't show up (as is the case in your Rows.Field code) - I think this may be what you are asking about in the UT thread.

Also bear in mind that when the query actually executes that the DataTable will need to be in scope. TBH, I have a gut feeling this is not a good approach. If you explain why you want this to actually execute in a different method maybe we can find an alternative...
