C# | Byte.CompareTo(Byte) Method

Last Updated : 07 Dec, 2021

This method is used to compare this instance to a specified 8-bit unsigned integer and returns an indication of their relative values.
Syntax:

public int CompareTo (byte value);

Here, the value is an 8-bit unsigned integer to compare.
Return Value: This method returns a signed integer that indicates the relative order of this instance and value.

Less than zero: This instance is less than value.
Zero: This instance is equal to value.
Greater than zero: This instance is greater than value.

Below programs illustrate the use of Byte.CompareTo(Byte) Method:
Example 1:

CSHARP

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

class GFG {

    // Main Method
    public static void Main()
    {

        // Declaring val1 and val2
        byte val1, val2;

        // initializing the val1, 
        // val2 and val3
        val1 = 12;
        val2 = 13;

        // getting compared constant
        // using CompareTo method
        int i = val2.CompareTo(val1);

        // checking the condition
        if (i > 0)
            Console.Write("val2 is greater than val1");

        else if (i < 0)
            Console.Write("val2 is less than val1");

        else
            Console.Write("val1 is equal to val1");
    }
}

Output:

val2 is greater than val1

Example 2:

CSHARP

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

class GFG {

    // Main Method
    public static void Main()
    {

        // checking the condition
        // calling check() method
        check((byte)10, (byte)20);
        check((byte)30, (byte)20);
        check((byte)10, (byte)10);
        check((byte)5, (byte)7);
        check((byte)40, (byte)50);
        check((byte)1, (byte)2);
    }

    // Defining the check method
    public static void check(byte v1, byte v2)
    {

        // getting compared constant
        // using CompareTo() method
        int i = v1.CompareTo(v2);

        // checking the condition
        if (i > 0)
            Console.WriteLine(v1 + " is greater than " + v2);

        else if (i < 0)
            Console.WriteLine(v1 + " is less than " + v2);

        else
            Console.WriteLine(v1 + " is equal to " + v2);
    }
}

Output:

10 is less than 20
30 is greater than 20
10 is equal to 10
5 is less than 7
40 is less than 50
1 is less than 2
