unable to specify an array (range of numbers) as integer

hi friends

where am i wrong here?

PS C:\>1..10 -is [int]

 false

[int]$array = 1..10

Cannot convert the "System.Object[]" value of type "System.Object[]" to type "System.Int32".

$array = 1..10

$array -as [int]

$array -is [int]

false

my goal is to use that array in the following command:

Get-random $array -count 3

[int]
