New-Object add-member - cannot add a member - powershell - powershell

Question

I have a problem :(
I have many errors when I add New object with the same name of property which previously Object .
"Add-Member : Cannot add a member with the name "ServerName" because a
member with that name already exists. To overwrite the member anyway,
add the Force par ameter to your command."
it works but with errors;)
Have someone a solution for me ??
Below example code :
$OutputObj = #()
$OutputObj += New-Object -TypeName PSobject
$OutputObj | Add-Member -MemberType NoteProperty -Name ServerName -Value "server1"
$OutputObj | Add-Member -MemberType NoteProperty -Name Status -Value "online"
$OutputObj | Add-Member -MemberType NoteProperty -Name Uptime -Value "01:20"
$OutputObj += New-Object -TypeName PSobject
$OutputObj | Add-Member -MemberType NoteProperty -Name ServerName -Value "server2"
$OutputObj | Add-Member -MemberType NoteProperty -Name Status -Value "online"
$OutputObj | Add-Member -MemberType NoteProperty -Name Uptime -Value "01340"

Answer 1

You are adding the member on the array, not on the object. Try the following:
$OutputObj = #()
$NewObj = New-Object -TypeName PSobject
$NewObj | Add-Member -MemberType NoteProperty -Name ServerName -Value "server1"
$NewObj | Add-Member -MemberType NoteProperty -Name Status -Value "online"
$NewObj | Add-Member -MemberType NoteProperty -Name Uptime -Value "01:20"
$OutputObj += $NewObj
$NewObj = New-Object -TypeName PSobject
$NewObj | Add-Member -MemberType NoteProperty -Name ServerName -Value "server2"
$NewObj | Add-Member -MemberType NoteProperty -Name Status -Value "online"
$NewObj | Add-Member -MemberType NoteProperty -Name Uptime -Value "01340"
$OutputObj += $NewObj
Alernatively, I would do the following:
$OutputObj = #()
$OutputObj += New-Object -TypeName PSobject -Property #{
ServerName = "server1"
Status = "Online"
Uptime = "01:20"
}
$OutputObj += New-Object -TypeName PSobject -Property #{
ServerName = "server2"
Status = "Online"
Uptime = "01340"
}
Since Add-Member destroys and generates a new object each time it is used.
