パワーシェルでコンボボックスのデフォルト値を設定する方法を誰かが知っているかどうか疑問に思っていましたか? ロード時に設定した配列 $OperatingSystemArray の最初のオブジェクトを表示したい。

これが私のコードです

$global:ComputerList = Get-Content c:\HostList.txt

# This holds the choices fro the Drop Down Menu

[array]$OperatingSystemArray = "-------------","Windows XP", "Windows 7"

# This function will grab a list of computers to work with from a .txt file

function Get-ComputerList {
    Write-Output "   List of Computers VMRest is going to be applied to:`n"
    Foreach ($Computer in $global:ComputerList) {
        Write-Output "     $Computer"
    }
    Write-Output "`n--------------------------------------------------------`n"
}

# This function will return the results of the $OperatingSystemArray and the execute commands based on the selection

function Get-OperatingSystems {

$Choice = $OSChoice.SelectedItem.ToString()

# Call correct function to run correct code

if ($Choice -match 'XP') {
    Write-Output "$Choice Base Machines selected"
    OS-WindowsXp
}
elseif ($Choice -match '7') {
    Write-Output "$Choice Base Machines selected"
    OS-Windows7
}
else {
    Write-Output "No valid Operating System Seleted"
 }
}

# This function will be called for the base machines that are running Windows XP

function OS-WindowsXp {
    Foreach ($Computer in $global:ComputerList) {
        Write-Output "Starting VMReset on $Computer"
    }
}

# This function will be called for the base machines that are running Windows 7

function OS-Windows7 {
    Foreach ($Computer in $global:ComputerList) {
       Write-Output "Starting VMReset on $Computer"
   }
}

$OSChoice コントロールの SelectedItem プロパティを既定値に設定しようとしましたか?

これが私が見ていたコードのスニペットです。それはかなり一般的ですが、あなたが求めることをしています:

 function set-controlvalue{
 param($control,
       $value)
       switch ($control.GetType().Name) {
        'TextBox' {
           $control.Text=$value 
        }
        'ComboBox' {
          $control.SelectedItem=$value
