Sounds strange. Since you are hashing each value, an array is more appropriate, an array of references to something. If you have enough RAM, you can simulate a big array as array of arrays, here size of 65536. Otherwise you could swap data to an external disk.

List list;

int dim = 65536;

list = new List();

for (int i = 0; i < dim; i++)

{

object[] array = new object[dim];

list.Add(array);

}
