SByte.CompareTo() Method in C# with Examples

SByte.CompareTo() Method is used to compare the current instance to a specified object or SByte and returns an indication of their relative values. There are 2 methods in the overload list of this method as follows:

• CompareTo(SByte) Method
• CompareTo(Object) Method

SByte.CompareTo(SByte) Method

This method is used to compare the current instance to a specified 8-bit signed integer and returns an indication of their relative values.

Syntax:

public int CompareTo (sbyte value);

Here, it takes the 8-bit signed integer to compare with the current instance.

Return Value: It returns a 32-bit signed number indicating the relative values 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

Below programs illustrate the use of SByte.CompareTo(SByte) Method:

Example 1:

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

class GFG {

    // Main Method
    public static void Main()
    {

        // Declaring and initializing value1
        sbyte value1 = 10;

        // Declaring and initializing value2
        sbyte value2 = 20;

        // compare both SByte value
        // 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);
    }
}

Output:

10 is less than 20

Example 2:

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

class GFG {

    // Main Method
    public static void Main()
    {
        // calling get() method
        get(5, 7);
        get(30, 20);
        get(10, 20);
        get(7, -12);
    }

    // defining get() method
    public static void get(sbyte value1,
                           sbyte value2)
    {

        // 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);
    }
}

Output:

5 is less than 7
30 is greater than 20
10 is less than 20
7 is greater than -12

SByte.CompareTo(Object) Method

This method is used to compare the current instance to a specified object and returns a comparison of their relative values.

Syntax:

public int CompareTo (object value);

Here, it takes the object to compare with this instance, or null.

Return Value: It returns a 32-bit signed number indicating the relative values 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

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

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

Example 1:

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

class GFG {

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

            // Declaring and initializing value1
            sbyte value1 = 10;

            // Declaring and initializing value2
            // explicit type casting the value 9
            object value2 = (sbyte)9;

            // compare both sbyte value
            // 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 SByte");
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

Output:

10 is greater than 9

Example 2: For ArgumentException

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

class GFG {

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

            // Declaring and initializing value1
            sbyte value1 = 10;

            // Declaring and initializing value2
            object value2 = 1 / 3;

            // 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 sbyte");
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

Output:

value2 must be sbyte
Exception Thrown: System.ArgumentException
