Question

Can I use C# Dictionary on classes like arrays??

Dictionary<double[],double[]>

I am afraid that it will not be able to tell when arrays are equal…

EDIT:

Will the hashing method in the dictionary take well care of arrays? or just hashing their references?

Answer 1

For array keys, the dictionary willuse the references for hashing and equality, which probably isn’t what you want. This leaves you with two choices: implement a wrapper class for double[], or (better) write something that implements IEqualityComparer and pass it to the Dictionary<T, T> constructor.
