UNDERSTAND VARIABLES AND TYPES 23
Getting Started with Windows PowerShell Basics
PART 1
In this example, we call the GetType() method of the string value “Tessa” . From
this, you can see that “Tessa” is a fully quali ed System.String object.
ESCAPE CHARACTER
Strings can be defi ned using either double quotes or single quotes. This is a conve-
nience feature that makes it easier to embed double or single quotes in a string without
having to escape the quote using the escape character (
` ):
PS C:\> “Tessa says: ‘Learn PowerShell!’”
Tessa says: ‘Learn PowerShell!’
PS C:\> ‘Tessa says: “Learn PowerShell!”’
Tessa says: “Learn PowerShell!”
PS C:\> “Tessa says: `”Learn PowerShell!`””
Tessa says: “Learn PowerShell!”
The escape character can also be used to break a command across multiple lines by
escaping the newline character:
PS C:\> $site = Get-SPSite `
>> “http://portal”
>>
PS C:\>
Here are a few more examples demonstrating some common built-in types:
PS C:\> $true.GetType().FullName
System.Boolean
PS C:\> (23).GetType().FullName
System.Int32
PS C:\> (23.0).GetType().FullName
System.Double
PS C:\> (2,3).GetType().FullName
System.Object[]
In the  rst example, you can see that, to use a Boolean value of True, you use the
built-in variable called $true (for False, use $false ).  e second and third exam-
ples demonstrate how to check the type of an integer or double value by wrapping
the value in parentheses. Parentheses are used a lot in PowerShell to control the
execution order.
 e last example is perhaps the most interesting. It creates an object array, which
is explained in more detail in the next section, but the interesting part is that
