When creating a 3D array in C#, which is a better way to create it?
Array[a,b,c] or Array[a][b][c]?
Or is it just a matter of preference?
These are two fundamentally different constructs. If one suits your requirements better than the other, prefer it as a matter of course.
Array[a,b,c] is a three dimensional, rectangular array. This means that all elements exist, but depending on your needs, may be sparsely populated. Array[a][b][c] is a three dimension jagged array, or an array of arrays of arrays.
All things being equal, I believe I once read a source (That I considered authoritative at the time) that the jagged array is generally preferable to the rectangular array. I don’t recall whether the reason was some sort of performance-related reason (caching?) or something else.
