Ping Multiple IP/HostNames - winforms

Question

I am just trying to make a simple IP/Hostname checker. The one part I am struggling with is getting it to ping each item from a list. It only shows the result of the first, or last one.
I have tried adding items from the text box into an array and pinging them that way, and it had the same results.
Here is my Current Code.
[System.Windows.Forms.Application]::EnableVisualStyles()
function ping-list{
$IPStatus.Text = ""
$names = #($IPList.text)
$Names | ForEach-Object{
if (Test-Connection -ComputerName $_ -Count 1){
$IPStatus.Text += "$_ is Online"
Write-Host "$_ is Online"
}
else{
$IPStatus.Text += "$_ is Offline"
Write-Host "$_ is Offline"
}
}
}
$Pinger = New-Object system.Windows.Forms.Form
$Pinger.ClientSize = '657,557'
$Pinger.text = "Pinger"
$Pinger.TopMost = $false
$IPStatus = New-Object system.Windows.Forms.TextBox
$IPStatus.multiline = $true
$IPStatus.width = 234
$IPStatus.height = 498
$IPStatus.enabled = $true
$IPStatus.location = New-Object System.Drawing.Point(408,45)
$IPStatus.Font = 'Microsoft Sans Serif,10'
$IPStatus.Text = "Ready"
$IPList = New-Object system.Windows.Forms.TextBox
$IPList.multiline = $true
$IPList.width = 234
$IPList.height = 498
$IPList.enabled = $true
$IPList.location = New-Object System.Drawing.Point(15,45)
$IPList.Font = 'Microsoft Sans Serif,10'
$IPList.Text = #("127.0.0.1")
$PingButton = New-Object system.Windows.Forms.Button
$PingButton.text = "button"
$PingButton.width = 60
$PingButton.height = 30
$PingButton.location = New-Object System.Drawing.Point(298,240)
$PingButton.Font = 'Microsoft Sans Serif,10'
$PingButton.Add_Click({ping-list})
$Pinger.controls.AddRange(#($IPStatus,$IPList,$PingButton))
$Pinger.Add_Shown( {$Pinger.Activate()})
$Pinger.ShowDialog()

Answer 1

$IPList.text gets all the text in the textbox.
Instead use Lines
function ping-list{
$IPStatus.Text = ""
$Names = #($IPList.Lines)
$Names | ForEach-Object{
if (Test-Connection -ComputerName $_ -Count 1){
$IPStatus.Text += "$_ is Online`r`n"
Write-Host "$_ is Online"
}
else{
$IPStatus.Text += "$_ is Offline`r`n"
Write-Host "$_ is Offline"
}
}
}
