Multidimensional Arrays and c sharp

You can think of arrays as long rows of slots into which values can be placed. Once you have a picture of a row of slots, imagine five rows, one on top of another. This is the classic two-dimensional array of rows and columns. The rows run across the array and the columns run up and down the array.

A third dimension is possible but somewhat harder to picture. Imagine making your arrays three-dimensional, with new rows stacked atop the old two-dimensional array. OK, now imagine four dimensions. Now imagine ten.

Those of you who are not string-theory physicists have probably given up, as have I. Multidimensional arrays are useful, however, even if you can't quite picture what they would look like. You might, for example, use a four-dimensional array to track movement in three dimensions (x,y,z) over time.

C# supports two types of multidimensional arrays: rectangular and jagged. In a rectangular array, every row is the same length. In a jagged array, however, each row can be a different length. In fact, you can think of each row in a jagged array as an array unto itself. Thus, a jagged array is actually an array of arrays.

Rectangular Arrays

A rectangular array is an array of two (or more) dimensions. In the classic two-dimensional array, the first dimension is the number of rows and the second dimension is the number of columns.

To declare a two-dimensional array, use the following syntax:

type  [,]  array-name 

A jagged array is an array of arrays. Specifically, a jagged array is a type of multi-dimensional array in which each row can be a different size from all the other rows. Thus, a graphical representation of the array has a "jagged" appearance.

You can think of each row in a jagged array as a one-dimensional array unto itself. Thus, technically speaking, a jagged array is an array of arrays. When you create a jagged array, you declare the number of rows in your array. Each row holds a one-dimensional array, and each row can be of any length. To declare a jagged array, use the following syntax, where the number of brackets indicates the number of dimensions of the array:

type [] []...

For example, you would declare a two-dimensional jagged array of integers named myJaggedArray as follows:

int [] [] myJaggedArray;

Address the elements in the array as follows: the array name then the offset into the array of arrays (the row), and then the offset into the chosen array (the column within the chosen row). That is, to access the fifth element of the third array, write:

myJaggedArray[2][4]

Remember that all arrays are zero-based. The third element is at offset 2, and the fifth element is at offset 4.
