How can you verify the equality of two objects based on their properties and data?

In C#, to check the equality of two objects based on their properties and data, it is common to override the Equals and GetHashCode methods. Reflection can also be used to compare all properties of objects dynamically.

Example of overriding Equals:

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }

    public override bool Equals(object obj)
    {
        if (obj == null || GetType() != obj.GetType())
            return false;

        Person other = (Person)obj;
        return Name == other.Name && Age == other.Age;
    }

    public override int GetHashCode()
    {
        return HashCode.Combine(Name, Age);
    }
}

If you need to compare objects without explicit overriding, you can use libraries such as Json.NET, serialize objects to JSON and compare the strings, or use specialized libraries for deep object comparison.
