you can select dynamically columns like x[mycolum] but your code fails because you return list of strings and trying to assign to a IEnumerable<datarow>, try below

C#

var rows = dt2.AsEnumerable().Where(r => r.Field<int32>("Year") == year).Select(x => x[mycolum].ToString()).ToList();

or

C#

List<string> rows = dt2.AsEnumerable().Where(r => r.Field<int32>("Year") == year).Select(x => x[mycolum].ToString()).ToList();
