Hello,

Hoping someone can help as i cant find an answer to this. In PowerShell i'm trying to add a new proprty to an array i have imported:

To confirm it looks like this when its imported:

PS C:\Windows\system32> $ImportedForAppend

ConnectionName : AlexanderSpirit 10.13.126.0 (vessel) (Not being upgraded)
ID             : 9c503373-a37f-4f08-9cce-748721b0238e
Status         : DOWN   :-(  25-02:1224
IP             : 10.13.126.250
PingNumber     : 0
TimeStamp      : 25-02-2020:1224

ConnectionName : BahrainSpirit 10.12.24.0 (vessel)
ID             : 8d2ce4a0-bacc-477d-89ca-a02f8d1014fd
Status         : FAST 174ms 25-02:1224
IP             : 10.12.24.250
PingNumber     : 174
TimeStamp      : 25-02-2020:1224

ConnectionName : BarcelonaSpirit 10.12.18.0 (vessel)
ID             : c7a783b5-e650-4023-a58b-2739038b1b8b
Status         : FAST 737ms 25-02:1224
IP             : 10.12.18.250
PingNumber     : 737
TimeStamp      : 25-02-2020:1224


PS C:\Windows\system32> $ImportedForAppend.GetType();

IsPublic IsSerial Name                                     BaseType                                                                                                                                                                                              
-------- -------- ----                                     --------                                                                                                                                                                                              
True     True     Object[]                                 System.Array        
             


Now i'm trying to add a new property to the array with an updated time stamp and a new ping number, so it looks like this:

ConnectionName : AlexanderSpirit 10.13.126.0 (vessel) (Not being upgraded)
ID             : 9c503373-a37f-4f08-9cce-748721b0238e
Status         : DOWN   :-(  25-02:1224
IP             : 10.13.126.250
PingNumber     : 0
TimeStamp      : 25-02-2020:1224
25-02-2020:1250:    677

ConnectionName : BahrainSpirit 10.12.24.0 (vessel)
ID             : 8d2ce4a0-bacc-477d-89ca-a02f8d1014fd
Status         : FAST 174ms 25-02:1224
IP             : 10.12.24.250
PingNumber     : 174
TimeStamp      : 25-02-2020:1224
25-02-2020:1250:   1344

ConnectionName : BarcelonaSpirit 10.12.18.0 (vessel)
ID             : c7a783b5-e650-4023-a58b-2739038b1b8b
Status         : FAST 737ms 25-02:1224
IP             : 10.12.18.250
PingNumber     : 737
TimeStamp      : 25-02-2020:1224
25-02-2020:1250:     566


Question is how to target a specific "ConnectionName" and add a new property with the name/value so the layout stays the same?

I know i can use the below to add a new member but its adding a property to each group and i want to only target certain ones:

$ImportedForAppend | Add-Member -MemberType NoteProperty -Name $Vessel.TimeStamp -Value $CurrentStatusList.PingNumber
