Hi i have changed the below method as static but the error will display as
"An object reference is required for non static method or property" at objEntity
var empList = (from empDetails in objEntity.HCM_EMPLOYEE_DETAILS
select empDetails).ToList();

When you do the Linq to Objects query, it will return you the type IEnumerable<Student>, you can use the ToList()[^] method to create a List<T> from an IEnumerable<T>:

XML

var selected = from s in studentCollection
                           select s;

List<Student> selectedCollection = selected.ToList();

This may help.
