如何插入我在powershell文件选择器gui中选择的文件？

Add-Type -AssemblyName System.Windows.Forms

$openFileDialog = New-Object System.Windows.Forms.OpenFileDialog
$openFileDialog.InitialDirectory = [Environment]::GetFolderPath('Desktop')
$openFileDialog.Filter = 'All files (*.*)|*.*'
$openFileDialog.Multiselect = $true

if ($openFileDialog.ShowDialog() -eq 'OK') {
    $selectedFiles = $openFileDialog.FileNames
    # 在这里可以处理选择的文件，例如读取文件内容或进行其他操作
}

foreach ($file in $selectedFiles) {
    $content = Get-Content $file
    Write-Host "File content of $file:"
    Write-Host $content
}
