从测试连接返回StatusCode

Question

test-connection server | select-object *

returns many properties, among them StatusCode.

How can I return only this value? My best guess would be

$r = test-connection server
$r.statuscode

but that doesn't work. How do I do it?

EDIT

http://msdn.microsoft.com/en-us/library/windows/desktop/aa394350%28v=vs.85%29.aspx has more information about the statuscode I would like to receive.. No luck yet!

Answer 1

Test-Connection by default will give you a collection (4 System.Management.ManagementObject objects). It uses the Win32_PingStatus WMI class internally.

(Test-Connection server).GetType().FullName

Outputs:

System.Object[]

So you can do this:

(Test-Connection server -Count 1).StatusCode

or this:

(Test-Connection server)[0].StatusCode

Don't forget, some pings may fail so if you just check one it may not necessary mean there's no connection.

You could also try calling Win32_PingStatus directly like this:

Get-WmiObject -Class Win32_PingStatus -Filter "Address='server'" | Select-Object -Property Address,ResponseTime,StatusCode

Answer 2

$r = test-connection computername -count 1
$r.statuscode

This works.

Answer 3

Why don't you just try :

$r = Test-Connection server -Quiet

$r is a boolean
