Visual Basic® 2010 Unleashed

Multidimensional and Jagged Arrays

Array literals also affect multidimensional and jagged arrays. The following line of code shows how you can declare a multidimensional array of integers taking advantage of array literals:

Dim multiIntArray = {{4, 3}, {2, 1}}

In this case you do not need to add parentheses. The Visual Basic compiler infers the type as follows:

Dim multiIntArray(,) As Integer = {{4, 3}, {2, 1}}

Figure 21.3 shows how you can check the inferred type by passing the mouse pointer over the declaration, getting a descriptive tooltip.

Array literals work similarly on a jagged array. ...
