Processing a multidimensional data structure in .Net 3.5 and higher

Question

I want to build a 2-dimensional (not dangling at this point) array of objects.

I can easily build a 2-dimensional Array [,] and will do it if it is the best option available, but tended to avoid arrays in favor of the extended functionality of the .NET List and Dictionary structures.

I could also use List <List <T →> to store a 2-dimensional array, but wondered if there were any best practices or implemented data structures in .NET 3.5 or higher to handle typed 2-dimensional structures with more flexible / comprehensive functionality than an array?

I'm not interested in SSAS / OLAP style answers.
