2D array each row can have different size?

Question

With a Jagged array every row can have different sizes. int[][] jagged = new int[3][]; jagged[0] = new int[2] {510}; jagged[1] = new int[5] {246810}; jagged[2] = new int[3] {91014}; Guys any comment?

Jagged arrays are faster and have different syntax. They are faster because they use the newarr vector IL calls internally.

Even if the rows have the same length a jagged array is sometimes preferable to a rectangular array because it's easy to extract a whole row and pass it to another method say for further processing. With a rectangular array you have to create a single dimensional array and copy elements to it for the row you're interested in.
