DataViewGrid 未显示预期数据

Question

我的问题是我不知道问题是什么。显示变量

$VMName

和

$Output

的内容有问题，如果您有任何解决方案，请告诉我。不起作用的部分用感叹号和主题标签圈起来。除此之外，我已经将脚本的最大部分复制到这里，以防有人想要测试它。

# Create the main window
$form = New-Object System.Windows.Forms.Form
$form.Text = "Serverkonfigurations-Export"

$DataGridView.ReadOnly = $true
$DataGridView.AllowUserToAddRows = $false
$DataGridView.AutoGenerateColumns = $false
$Form.Controls.Add($DataGridView)

# Create columns
$Column1 = New-Object Windows.Forms.DataGridViewTextBoxColumn
$Column1.Name = "VM Name"
$Column1.HeaderText = "VM Name"
$Column1.Width = 272
$DataGridView.Columns.Add($Column1)

$Column2 = New-Object Windows.Forms.DataGridViewTextBoxColumn
$Column2.Name = "CPU/RAM"
$Column2.HeaderText = "CPU/RAM"
$Column2.Width = 175
$DataGridView.Columns.Add($Column2)

# Get virtual machines
$VMs = Get-SCVirtualMachine | Where-Object {$_.Name -like "*xenapp1*"}

#Start foreach-Schleife
foreach($VM in $VMs){

    $ProcessorCount = $VM.CPUCount
    $Memory = $VM.Memory
    $MemoryConfiguration = $VM.DynamicMemoryEnabled
    $MemorySize = $Memory / "1024"

    # Format for Output
    $OutputFormat = "{0}c/{1}G{2}"
    if($MemoryConfiguration -eq $true){

        $MemoryUnit = "d"
    }
    else{

        $MemoryUnit = "s"
    }

    # Result Output
    $VMName = $VM.Name 
    $Output = $OutputFormat -f $ProcessorCount, $MemorySize, $MemoryUnit

    $Output1 = [PSCustomObject]@{
        VMName = $VMName
        Config = $Output
    }  

}

这些是我执行脚本时出现的错误。
