Binding to ASP.NET GridView

var emp = new List<Employee>
{
   new Employee{ID=1, EmpFname="matt", EmpLName="Cook"},
   new Employee{ID=2, EmpFname="mary", EmpLname="John"}
};

List<Employee> temp = new List<Employee> {
            new Employee { ID = 1, EmpFname = "matt", EmpLName = "Cook" },
            new Employee { ID = 2, EmpFname = "mary", EmpLName = "John" } };

        temp.Sort(delegate(Employee e1, Employee e2)
        {
            // returns asc
            return e1.EmpLName.CompareTo(e2.EmpLName);
           // returns desc
           //  return e2.EmpLName.CompareTo(e1.EmpLName);

        });

        // no need to use var keyword, just bind the List
        MyGridView.DataSource = temp;
        MyGridView.DataBind();

var sortedEmpList = ( from e in emp
orderby e.EmpLName
select e).ToList()
);

orderby e.EmpLName, e.EmpFName  //, ...

orderby e.EmpLName descending
