Oops output question

What would be output of following program ?

class Program
    {
        static void Main(string[] args)
        {
            Student student = new Student();
            Show(student);
            Display(student);
            student.P2 = "Main";
            Console.WriteLine(student.P + " == " + student.P1 + " == " + student.P2 + " " + student.GetHashCode());
            Console.ReadLine();
        }

        static void Show(Student student)
        {
            var localStudent = student;
            localStudent.P = "Show";
        }
        static void Display(Student student)
        {
            var localStudent = student;
            localStudent.P1 = "Display";
        }
    }

    public class Student
    {
        public string P;
        public string P1;
        public string P2;
    }
 

Output :
