powershell- savefiledialog暂时创建txt文件

Question

我想在PowerShell中创建一个GUI，在该GUI中，用户选择一个保存空TXT文件的路径。为此，我使用SaveFileDialog。当我运行下面的代码时，文件将暂时创建。它不是永久保存的。我需要改变什么？

Function fileSave
{
$OpenFileDialog = New-Object System.Windows.Forms.SaveFileDialog
$OpenFileDialog.CheckPathExists = $true
$OpenFileDialog.CreatePrompt = true;
$OpenFileDialog.OverwritePrompt = true;
$OpenFileDialog.initialDirectory = $initialDirectory
$Directory = $OpenFileDialog.FileName = 'NewFile'
$OpenFileDialog.Title = 'Choose directory to save the output file'
$OpenFileDialog.filter = "Text documents (.txt)|*.txt"

# Show save file dialog box
if($OpenFileDialog.ShowDialog() -eq 'Ok'){
    $NewFile = New-Item -Path "$Directory" -ItemType File -Force
}

您想引用 fileName属性在您的内部，如果条件，它将是文件的绝对路径创建。除此之外，您还使用true而不是$ true。

Add-Type -AssemblyName System.Windows.Forms

Function fileSave {
    $saveFileDialog = [System.Windows.Forms.SaveFileDialog]@{
        CheckPathExists  = $true
        CreatePrompt     = $true
        OverwritePrompt  = $true
        InitialDirectory = [Environment]::GetFolderPath('MyDocuments')
        FileName         = 'NewFile'
        Title            = 'Choose directory to save the output file'
        Filter           = "Text documents (.txt)|*.txt"
    }

    # Show save file dialog box
    if($saveFileDialog.ShowDialog() -eq 'Ok') {
        New-Item -Path $saveFileDialog.FileName -ItemType File -Force
    }
}

fileSave
