An object in C# has four methods – {Equals, GetType, ToString, GetHashCode}.
What sort of useful thing could someone do with the hash-code?
Quickly find potentially equal objects.
In particular, this method is usually used by types such as
Dictionary<TKey, TValue>(for the keys) andHashSet<T>.You should not assume that objects with equal hash codes are equal, however. See Eric Lippert’s blog post for more information, and the Wikipedia hash table page for a more general discussion on the uses of hash codes.
