Arrays

To PowerShell, arrays are simply a listing of data. They can be used for various tasks and can be created easily, as you can see here:

PS>$var="foo","bar"PS>$varfoobarPS>

In this example, an array is created with two values, and then it is simply invoked, which results in outputting each element of the array, one per line. When an array is created, a reference can be made to a particular element of the array using a special [] syntax, like this:

PS>$var[0]fooPS>

Note

The first element of an array is the element zero; therefore, the first record in an array is retrieved by referencing the element id [0].

The count property is also useful as a property of array objects (remember that everything in PowerShell is a .NET object:

PS>$var.count ...
