从DataGridView导出

Question

我需要在PowerShell GUI上创建一个按钮，以在按下时保存DataGridView的内容。这需要打开一个文件对话框以选择目标位置并为其指定文件名。

查看代码以了解我已经尝试过的内容

$btnSave_Click={
    $saveFile = New-Object System.Windows.Forms.SaveFileDialog
    $saveFile.Filter = "Comma Delimited (*.csv) | *.csv "
    $saveFile.FileName
    if ($saveFile.ShowDialog() -eq 'OK')
    {
        $results.SelectAll()
        $results.ClipboardCopyMode = 'EnableAlwaysIncludeHeaderText'
        $results.GetClipboardContent().GetData('Text') | Out-File 
    $saveFile.FileName
    }
}

收到的错误是
