assistance with getting part of value with powershell

I need assistance with a powershell script.

I have a value - 2.0.0.0 (it could be any value seperated with the 3 full stops)

I want to just get the first three numbers eg 2.0.0

With powershell, how can I do this?

A regular expression is a flexible way to do this:

"1.2.3.4" -replace "(.*)\.(.*)\.(.*)\.(.*)",'$1.$2.$3'

or inspired by Shay Levy's answer:

You could use the toString method with a fieldcount of three:

([version]"1.2.3.4").tostring(3)

Here's another way:

 PS> '2.0.0.0'.split('.')[0..2] -join '.'
 2.0.0

By the way, you can cast it to a system.version object and work with it's properties:

PS> [version]'2.0.0.0'

Nothing at all wrong with the other answers, but just to show more diversity:

[string]::Join('.', '2.0.0.0'.Split('.')[0..2])

Like this:

$a =  "2.0.0.0"

$a.Remove( $a.LastIndexOf('.') )

2.0.0
