How to best implement Equals for custom types?

Question

Say for a Point2 class, and the following Equals:

public override bool Equals ( object obj )

public bool Equals ( Point2 obj )

This is the

Answer 1

The simple and best way to override Equals looks like:

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

        public override bool Equals(object other)
        {
            Person otherItem = other as Person;

            if (otherItem == null)
                return false;

            return Age == otherItem.Age && Name == otherItem.Name;
        }
        public override int GetHashCode()
        {
            int hash = 13;
            hash = (hash * 7) + Age.GetHashCode();
            hash = (hash * 7) + Name.GetHashCode();
            return hash;
        }
    }

Override the GetHashCode method to allow a type to work correctly in a hash table.
