Question

Employee emp1 = new Employee {Name = "Swapnil",Age = 27 };
            Employee emp2 = new Employee { Name = "Swapnil", Age = 27 };
            if (object.Equals(emp1, emp2))
            {

            }
            else
            {
            }

This code is not able to compare.
How i can compare two Object s in C# ?

Answer 1

Without overriding the Equals method only a reference comparison willoccur. You want to perform a value comparison.

Override the method in your Employee class like so:

public override bool Equals(Object emp)
{
    // If parameter is null return false.
    if (emp == null)
    {
        return false;
    }

     // If parameter cannot be cast to Point return false.
    Employee e = emp as Employee;
    if ((System.Object)e == null)
    {
        return false;
    }

    // Return true if the fields match
    return (Name == emp.Name) && (Age == emp.Age);
}

Then compare the objects like so:

if(emp1.Equals(emp2))
{ ... }

OR with the comparison operator:

if(emp1 == emp2)
{ ... }
