Bagaimana untuk mengisih senarai jenis kompleks menggunakan perwakilan perbandingan dalam C#?

Lebihan kaedah Sort() dalam kelas List memerlukan perwakilan Perbandingan Lulus sebagai parameter. .

Kaedah Int16.CompareTo() dalam C# digunakan untuk membandingkan kejadian ini dengan contoh yang ditentukan Objek atau contoh Int16 yang lainContoh

class Program{
   public static void Main(){
      Employee Employee1 = new Employee(){
         ID = 101,
         Name = "Mark",
         Salary = 4000
      };
      Employee Employee2 = new Employee(){
         ID = 103,
         Name = "John",
         Salary = 7000
      };
      Employee Employee3 = new Employee(){
         ID = 102,
         Name = "Ken",
         Salary = 5500
      };
      List<Employee> listEmployees = new List<Employee>();
      listEmployees.Add(Employee1);
      listEmployees.Add(Employee2);
      listEmployees.Add(Employee3);
      Console.WriteLine("Employees before sorting");
      foreach (Employee Employee in listEmployees){
         Console.WriteLine(Employee.ID);
      }
      listEmployees.Sort((x, y) => x.ID.CompareTo(y.ID));
      Console.WriteLine("Employees after sorting by ID");
      foreach (Employee Employee in listEmployees){
         Console.WriteLine(Employee.ID);
      }
      listEmployees.Reverse();
      Console.WriteLine("Employees in descending order of ID");
      foreach (Employee Employee in listEmployees){
         Console.WriteLine(Employee.ID);
      }
   }
   // Approach 1 - Step 1
   // Method that contains the logic to compare Employees
   private static int CompareEmployees(Employee c1, Employee c2){
      return c1.ID.CompareTo(c2.ID);
   }
}
public class Employee{
   public int ID { get; set; }
   public string Name { get; set; }
   public int Salary { get; set; }
}

Output

Employees before sorting
101
103
102
Employees after sorting by ID
101
102
103
Employees in descending order of ID
103
102
101
