Jagged arrays are different than multidimensional arrays. Multidimensional arrays have a rank greater than one, with a separate indexer and a size for each rank. Jagged arrays are just an array of arrays.
You can create an array which is both jagged and multidimensional. Here’s an example (a two-dimensional array of arrays).

| // Multidimensional / jagged array. E.g. store array// of phone call objects for each day of the week,// each hour of the day.PhoneCall[,][] weeklyCallLog = new PhoneCall[7, 24][];// Record 2 calls for Monday between 8-9 AMweeklyCallLog[1 ,8] = new PhoneCall[2];weeklyCallLog[1, 8][0] = thisCall;weeklyCallLog[1, 8][1] = thatCall; |
Here’s another example (an array of two-dimensional arrays):
