could you please let me know what is wrong with this code?

Question

[void][System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
[void][Reflection.Assembly]::LoadWithPartialName("System.Drawing")

$form = New-Object System.Windows.Forms.Form
$form.Size = New-Object System.Drawing.Size(900,600)

$ColName = @{Expression={$_.CSNAME};Label="SERVER NAME"},
           @{Expression={$_.Caption};Label="OS NAME"; width =25},
           @{Expression={$_.OSArchitecture};Label="OS TYPE"}
$out = Get-WmiObject Win32_OperatingSystem -ComputerName "suman-pc" |
       Format-Table -HideTableHeaders $ColName

list = New-Object System.Collections.ArrayList
$list.Insert($out)

$dataGridView = New-Object System.Windows.Forms.DataGridView -Property @{
  Size=New-Object System.Drawing.Size(800,400)
  ColumnHeadersVisible = $true
  DataSource = $list
}

$form.Controls.Add($dataGridView)
$form.ShowDialog()

The above code is generating the below error. my objective is collect OS name for multiple system, and present it in datagrid format

New-List : Cannot bind parameter 'MarkerOffset'. Cannot convert value
"System.Collections.ArrayList" to type "System.Double". Error: "Input string
was not in a correct format."

I have found a couple of reasons here.

First you dont want to use Format-Table since it goes only as representive output.

Second you using wrong method, you should using $list.Add() instead of $list.Insert()

Here's fixed code:

[void][System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
[void][Reflection.Assembly]::LoadWithPartialName("System.Drawing")

$form = New-Object System.Windows.Forms.Form
$form.Size = New-Object System.Drawing.Size(900,600)

$ColName = @{Expression={$_.CSNAME};Label="SERVER NAME"},
           @{Expression={$_.Caption};Label="OS NAME";},
           @{Expression={$_.OSArchitecture};Label="OS TYPE"}
$out = Get-WmiObject Win32_OperatingSystem -ComputerName "suman-pc" | Select-Object $ColName

$list = New-Object System.Collections.ArrayList
[void]$list.Add($out)

$dataGridView = New-Object System.Windows.Forms.DataGridView -Property @{
  Size=New-Object System.Drawing.Size(800,400)
  ColumnHeadersVisible = $true
  DataSource = $list
}

$form.Controls.Add($dataGridView)
$form.ShowDialog()
