How can to check if two object values are equal in C#

In C#, we can check if two object values are equal with the Equals() method. This method is used to get a Boolean value that indicates whether or not a certain value is equal to another.

Syntax

public virtual bool Equals (object obj);

Parameters

obj: This is the object we pass to the Equals() method to check if it is equal to a particular object or not.

Return value

A boolean value is returned. It returns true if two objects are equal, else, a false is returned.

Code example

In the example below, we will create some values and check if they are equal to one another, using the Equals() method.

// use System
using System;
// create class
class EqualityChecker
{
    // main method
    static void Main()
    {
        // create some values
        string name = "Johnny";
        string platform = "Edpresso";
        bool isGreat = true;
        bool isHard = false;
        bool isCSharp = true;
        int num1 = 3 + 4;   // = 7
        int num2 = 5 + 6;   // = 13

        // compare them using 
        // the `Equals()` method
        PrintEquals((string)name, (string)platform);
        PrintEquals(name, name);
        PrintEquals(isGreat, isHard);
        PrintEquals(isGreat, isCSharp);
        PrintEquals(num1, num2);
        PrintEquals(num1, num1);
    }

    // check string objects method
    static void PrintEquals(object obj1, object obj2){
        if(obj1.Equals(obj2)){
             Console.WriteLine("Both of the values are equal");
        }else{
             Console.WriteLine("Both of the values are not equal");
        }
    }
}
