C# | Byte.CompareTo(Object) Method

This method is used to compare the current instance to a specified object and returns a sign of their relative values. Regardless of value, any instance of Byte will be considered greater than null.

Syntax:

public int CompareTo (object value);

Here, it takes an object to compare, or null.

Return Value: It returns a signed integer indicating the relative order of current instance and value parameter as follows:

• Less than Zero: if Current Instance < value
• Zero: if Current Instance = value
• Greater than Zero: if Current Instance > value or value is null.

Exception: It throws ArgumentException if value is not an Byte.

Below programs illustrate the use of Byte.CompareTo(Object) Method

Example 1:

// C# program to demonstrate the
// Byte.CompareTo(object) Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {
        try {

            // Declaring and initializing value1
            byte value1 = 10;

            // Declaring and initializing value2
            // converting to byte using explicit
            // type casting
            object value2 = (byte)87;

            // using CompareTo() method
            int status = value1.CompareTo(value2);

            // checking the status
            if (status > 0)
                Console.WriteLine("{0} is greater than {1}",
                                            value1, value2);

            else if (status < 0)
                Console.WriteLine("{0} is less than {1}",
                                         value1, value2);
            else
                Console.WriteLine("{0} is equal to {1}",
                                        value1, value2);
        }

        catch (ArgumentException e)
        {
            Console.WriteLine("value2 must be Byte");
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

Output:

10 is less than 87

Example 2: For ArgumentException

// C# program to demonstrate the
// Byte.CompareTo(object) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        try {

            // Declaring and initializing value1
            byte value1 = 10;

            // Declaring and initializing value2
            object value2 = (long)569874514;

            // using CompareTo() method
            int status = value1.CompareTo(value2);

            // checking the status
            if (status > 0)
                Console.WriteLine("{0} is greater than {1}",
                                            value1, value2);

            else if (status < 0)
                Console.WriteLine("{0} is less than {1}",
                                         value1, value2);
            else
                Console.WriteLine("{0} is equal to {1}",
                                        value1, value2);
        }

        catch (ArgumentException e)
        {
            Console.WriteLine("value2 must be Byte");
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

Output:

value2 must be Byte
Exception Thrown: System.ArgumentException
