PowerShell sends the items in an array one at a time when you pipe an array to Get-Member and it ignores duplicates
'@
$tip.Example = @'
# When you pipe to Get-Member PowerShell enumerates the array and you get the properties of the items inside the array, in this case a string
PS C:\> [array]$myArray = @('one','two','three')
PS C:\> $myArray | Get-Member

   TypeName: System.String

# This example will output the members of the array
PS C:\> Get-Member -InputObject $myArray

   TypeName: System.Object[]

# This will also do the same by making the array the second item in an array of arrays
,$myArray | Get-Member

# To see what type of object is in a variable use the GetType method.
PS C:\> $myArray.GetType()
