浏览打开窗口，打开运行窗口，文件夹

创建浏览打开窗口的函数：

function Read-FolderBrowserDialog([string]$InitialDirectory)
{
    $app = New-Object -ComObject Shell.Application
    $folder = $app.BrowseForFolder(0, "Please Select a Folder", 0, $InitialDirectory)
    if ($folder) { return $folder.Self.Path } else { return "未选中任何文件夹" }
}

#运行函数
 Read-FolderBrowserDialog d:

结果：

 $folder = Read-FolderBrowserDialog d:

 $folder 结果为 选中的文件夹路径

#打开桌面选项
$desktoppath = [Environment]::GetFolderPath("Desktop")
Read-FolderBrowserDialog $desktoppath

 $app = New-Object -ComObject Shell.Application

浏览文件路径：

function Read-OpenFileDialog([string]$InitialDirectory, [string]$Filter = "All files (*.*)|*.*", [switch]$AllowMultiSelect)
{
    
    Add-Type -AssemblyName System.Windows.Forms
    $openFileDialog = New-Object System.Windows.Forms.OpenFileDialog
    if ($InitialDirectory.tostring().length -lt 1) { $InitialDirectory = [Environment]::GetFolderPath("Desktop") }
    $openFileDialog.InitialDirectory = $InitialDirectory
    $openFileDialog.Filter = $Filter
    if ($AllowMultiSelect) { $openFileDialog.MultiSelect = $true }
    $openFileDialog.ShowHelp = $true    # Without this line the ShowDialog() function may hang depending on system configuration and running from console vs. ISE.
    $openFileDialog.ShowDialog() > $null
    if ($AllowMultiSelect) { return $openFileDialog.Filenames }
    else { return $openFileDialog.Filename }
}
Read-OpenFileDialog "d:"

打开“运行”窗口：

$app = New-Object -ComObject Shell.Application
$app.filerun()
