How to make use of both Take and Skip operator together in LINQ C# Programming

We are creating two instances of the Employee class, e and e1. The e is assigned to e1. Both objects are pointing to the same reference, hence we will get true as expected output for all the Equals.

In the second case we can observe that, even though properties values are same. Equals returns false. Essentially, when arguments are referring to different objects. Equals don’t check for the values and always returns false.

Example 1

class Program{
   static void Main(string[] args){
      Employee e = new Employee();
      e.Name = "Test";
      e.Age = 27;
      Employee e2 = new Employee();
      e2 = e;
      var valueEqual = e.Equals(e2);
      Console.WriteLine(valueEqual);
      //2nd Case
      Employee e1 = new Employee();
      e1.Name = "Test";
      e1.Age = 27;
      var valueEqual1 = e.Equals(e1);
      Console.WriteLine(valueEqual1);
      Console.ReadLine();
   }
}
class Employee{
   public int Age { get; set; }
   public string Name { get; set; }
}

Output

True
False

Example 2

class Program{
   static void Main(string[] args){
      Employee e = new Employee();
      e.Name = "Test";
      e.Age = 27;
      Employee e2 = new Employee();
      e2 = e;
      var valueEqual = e.Equals(e2);
      Console.WriteLine(valueEqual);
      Employee e1 = new Employee();
      e1.Name = "Test";
      e1.Age = 27;
      var valueEqual1 = e.Equals(e1);
      Console.WriteLine(valueEqual1);
      Console.ReadLine();
   }
}
class Employee{
   public int Age { get; set; }
   public string Name { get; set; }
   public override bool Equals(object? obj){
      if (obj == null)
      return false;
      if (this.GetType() != obj.GetType()) return false;
      Employee p = (Employee)obj;
      return (this.Age == p.Age) && (this.Name == p.Name);
   }
   public override int GetHashCode(){
      return Age.GetHashCode() ^ Name.GetHashCode();
   }
}

Output

True
True
