Int32.Equals Method in C# with Examples

Int32.Equals() Method is used to get a value which indicates whether the current instance is equal to a specified object or Int32 or not. There are two methods in the overload list of this method as follows:

• Equals(Int32) Method
• Equals(Object) Method

Int32.Equals(Int32)

This method is used to return a value indicating whether the current instance is equal to a specified Int32 value or not.

Syntax: public bool Equals (int obj);
Here, it takes a Int32 value to compare to this instance.

Return Value: This method returns true if obj has the same value as this instance otherwise, false.

Below programs illustrate the use of Int32.Equals(Int32) Method:

Example 1:

// C# program to demonstrate the
// Int32.Equals(Int32) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // Declaring and initializing value1
        int value1 = 4562;

        // Declaring and initializing value2
        int value2 = 2563;

        // using Equals(Int32) method
        bool status = value1.Equals(value2);

        // checking the status
        if (status)
            Console.WriteLine("{0} is equal to {1}",
                                    value1, value2);
        else
            Console.WriteLine("{0} is not equal to {1}",
                                        value1, value2);
    }
}

Output:

4562 is not equal to 2563

Example 2:

// C# program to demonstrate the
// Int32.Equals(Int32) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {

        // calling get() method
        get(455, 578);
        get(445, 445);
        get(10, 20);
        get(Int32.MaxValue, Int32.MinValue);
    }

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

        // using Equals(Int32) method
        bool status = value1.Equals(value2);

        // checking the status
        if (status)
            Console.WriteLine("{0} is equal to {1}",
                                    value1, value2);
        else
            Console.WriteLine("{0} is not equal to {1}",
                                        value1, value2);
    }
}

Output:

455 is not equal to 578
445 is equal to 445
10 is not equal to 20
2147483647 is not equal to -2147483648

Int32.Equals(Object) Method

This method is used to returns a value indicating whether the current instance is equal to a specified object or not.

Syntax: public override bool Equals (object obj);
Here, it takes an object to compare with this instance.

Return Value: This method returns true if obj is an instance of Int32 and equals the value of this instance otherwise, false.

Below programs illustrate the use of the above-discussed method:

Example 1:

// C# program to demonstrate the
// Int32.Equals(Object) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // Declaring and initializing value1
        int value1 = 10;

        // Declaring and initializing value2
        object value2 = 1 / 45;

        // using Equals(object) method
        bool status = value1.Equals(value2);

        // checking the status
        if (status)
            Console.WriteLine("{0} is equal to {1}",
                                    value1, value2);
        else
            Console.WriteLine("{0} is not equal to {1}",
                                        value1, value2);
    }
}

Output:

10 is not equal to 0

Example 2:

// C# program to demonstrate the
// Int32.Equals(Object) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // calling get() method
        get(547, 585);
        get(555, 489);
        get(100, 100);
        get(745, 725);
    }

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

        // compare both Int32 value
        // using Equals(object) method
        bool status = value1.Equals(value2);

        // checking the status
        if (status)
            Console.WriteLine("{0} is equal to {1}",
                                    value1, value2);
        else
            Console.WriteLine("{0} is not equal to {1}",
                                        value1, value2);
    }
}

Output:

547 is not equal to 585
555 is not equal to 489
100 is equal to 100
745 is not equal to 725
