The Byte.GetHashCode() method in C# is used to return the hash code for the current instance.SyntaxFollowing is the syntax −public override int GetHashCode ();ExampleLet us now see an example to implement the Byte.GetHashCode() method −using System; public class Demo {    public static void Main(){       long val = 5654665;       byte[] arr = BitConverter.GetBytes(val);       for (int i = 0; i < arr.Length; i++) {          int res = arr[i].GetHashCode();          Console.WriteLine("Hashcode = "+res);       }    } }OutputThis will produce the following output −Hashcode = 137 Hashcode = 72 Hashcode = 86 Hashcode = 0 Hashcode = 0 Hashcode = 0 Hashcode = 0 Hashcode = 0

The Byte.Equals(Object) method in C# returns a value indicating whether this instance is equal to a specified object.SyntaxFollowing is the syntax −public override bool Equals (object ob);Above, ob is an object to compare with this instance or null.ExampleLet us now see an example to implement the Byte.Equals(Object) method −using System; public class Demo {    public static void Main(){       byte b1;       b1 = 5;       object b2 = 5/10;       if (b1.Equals(b2))          Console.Write("b1 = b2");       else          Console.Write("b1 is not equal to b2");    } }OutputThis will produce the following output −b1 is not equal to b2

The Boolean.CompareTo(Object) method in C# compares this instance to a specified object and returns an integer that indicates their relationship to one another.SyntaxFollowing is the syntax −public int CompareTo (object ob);Above, the parameter ob is an object to compare to this instance, or null.ExampleLet us now see an example to implement the Boolean.CompareTo(Object) method −using System; public class Demo {    public static void Main(){       bool b1 = false;       object b2 = false;       int res = b1.CompareTo(b2);       if (res > 0)          Console.Write("b1 > b2"); ...

The DateTime.IsLeapYear() method in C# is used to check whether the specified year is a leap year. The return value is a boolean, with TRUE if the year is a leap year, else FALSE.SyntaxFollowing is the syntax −public static bool IsLeapYear (int y);Above, y is the year to be checked, 2010, 2016, 2019, etc.ExampleLet us now see an example to implement the DateTime.IsLeapYear() method −using System; public class Demo {    public static void Main() {       int year = 2019;       Console.WriteLine("Year = "+year);       if (DateTime.IsLeapYear(year)){          Console.WriteLine("Leap Year!"); ...
