There are times when you need to determine if 2 objects are equal or not. In these cases, you could either override the Equals method or implement IEquatable interface.
How to find if 2 Objects are Equal in C#?
Below is a sample code snippet demonstrating the usage of Object.Equals method to find the equality of 2 objects.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ACSampleCode
{
class Program
{
static void Main(string[] args)
{
Employee emp = new Employee { Name = "ACMarc", Designation = "Chief Architect" };
Employee emp1 = new Employee { Name = "ACMarc", Designation = "Software Engineer" };
Employee emp2 = new Employee { Name = "Tester", Designation = "Tester" };
Console.WriteLine(emp.Equals(emp1));
Console.WriteLine(emp.Equals(emp2));
Console.ReadLine();
}
}
public class Employee
{
public string Name { get; set; }
public string Designation { get; set; }
public override bool Equals(object obj)
{
Employee compared = (Employee)obj;
if (compared.Name == Name)
return true;
else
return false;
}
}
}
