Question

I have WPF application project and I’m using EF.
I want something like this.

NorthwindEntities nwModel = new NorthwindEntities();
Employees emp;
List mylist = GenericFunc("emp.FirstName"); => returns a List<string>
and
List mylist = GenericFunc("emp.PostalCode"); => returns a List<int>

public static List<T> GenericFunc<T>(string myfield)
{...}

Sorry if I made any mistakes.

If you use a string paramter to represent a filed so :

public static List<T> GenericFunc<T>(string myfield, string TABLENAME)
{
   return nwModel.ExecuteQuery<T>("SELECT " + myfield + " FROM " + TABLENAME).ToList();
}
