Question

这就是我想要的

$x = Get-Process
$y = Get-Date -Format yyyy-MM-dd_hh.mmtt

$SelPath = Read-Host -Prompt "Choose a location to save the file?"
$Path = $SelPath + 'Running Process' + ' ' + $FixedDate + '.txt'

$x | Out-File $Path

Answer 1

“ Read-Host”。例如：

$folder = Read-Host "Folder location"

Answer 2

尽管注释中提供的链接显示了FolderBrowserDialog的使用，但所有这些都无法将其显示为Topmost表单，并且在完成后也不会处理该表单。

这里有两个功能可确保对话框显示在顶部。

第一个使用Shell.Application Com对象：

# Show an Open Folder Dialog and return the directory selected by the user.
function Get-FolderName {
    [CmdletBinding()]
    param (
        [Parameter(Mandatory=$false, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true, Position=0)]
        [string]$Message = "Select a directory.",

        [string]$InitialDirectory = [System.Environment+SpecialFolder]::MyDocuments,

        [switch]$ShowNewFolderButton
    )

    $browserForFolderOptions = 0x00000041                                  # BIF_RETURNONLYFSDIRS -bor BIF_NEWDIALOGSTYLE
    if (!$ShowNewFolderButton) { $browserForFolderOptions += 0x00000200 }  # BIF_NONEWFOLDERBUTTON

    $browser = New-Object -ComObject Shell.Application
    # To make the dialog topmost, you need to supply the Window handle of the current process
    [intPtr]$handle = [System.Diagnostics.Process]::GetCurrentProcess().MainWindowHandle

    # see: https://msdn.microsoft.com/en-us/library/windows/desktop/bb773205(v=vs.85).aspx
    $folder = $browser.BrowseForFolder($handle, $Message, $browserForFolderOptions, $InitialDirectory)

    $result = $null
    if ($folder) {
        $result = $folder.Self.Path
    }

    # Release and remove the used Com object from memory
    [System.Runtime.Interopservices.Marshal]::ReleaseComObject($browser) | Out-Null
    [System.GC]::Collect()
    [System.GC]::WaitForPendingFinalizers()

    return $result
}

$folder = Get-FolderName
if ($folder) { Write-Host "You selected the directory: $folder" }
else { "You did not select a directory." }

第二个使用一些C＃代码来实现“最高”功能和System.Windows.Forms

function Get-FolderName {
    [CmdletBinding()]
    param (
        [Parameter(Mandatory=$false, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true, Position=0)]
        [string]$Message = "Please select a directory.",

        [System.Environment+SpecialFolder]$InitialDirectory = [System.Environment+SpecialFolder]::MyDocuments,

        [switch]$ShowNewFolderButton
    )

    # To ensure the dialog window shows in the foreground, you need to get a Window Handle from the owner process.
    # This handle must implement System.Windows.Forms.IWin32Window
    # Create a wrapper class that implements IWin32Window.
    # The IWin32Window interface contains only a single property that must be implemented to expose the underlying handle.
    $code = @"
using System;
using System.Windows.Forms;

public class Win32Window : IWin32Window
{
    public Win32Window(IntPtr handle)
    {
        Handle = handle;
    }

    public IntPtr Handle { get; private set; }
}
"@

    if (-not ([System.Management.Automation.PSTypeName]'Win32Window').Type) {
        Add-Type -TypeDefinition $code -ReferencedAssemblies System.Windows.Forms.dll -Language CSharp
    }
    # Get the window handle from the current process
    # $owner = New-Object Win32Window -ArgumentList ([System.Diagnostics.Process]::GetCurrentProcess().MainWindowHandle)
    # Or write like this:
    $owner = [Win32Window]::new([System.Diagnostics.Process]::GetCurrentProcess().MainWindowHandle)

    # Or use the the window handle from the desktop
    # $owner =  New-Object Win32Window -ArgumentList (Get-Process -Name explorer).MainWindowHandle
    # Or write like this:
    # $owner = [Win32Window]::new((Get-Process -Name explorer).MainWindowHandle)

    Add-Type -AssemblyName System.Windows.Forms
    $dialog = New-Object System.Windows.Forms.FolderBrowserDialog
    $dialog.Description = $Message
    $dialog.RootFolder  = $InitialDirectory
    # $dialog.SelectedPath = ''  # a folder within the RootFolder to pre-select
    $dialog.ShowNewFolderButton = if ($ShowNewFolderButton) { $true } else { $false }

    $result = $null
    if ($dialog.ShowDialog($owner).ToString() -eq 'OK') { 
        $result = $dialog.SelectedPath
    }

    # clear the FolderBrowserDialog from memory
    $dialog.Dispose()

    return $result
}

$folder = Get-FolderName -InitialDirectory MyPictures
if ($folder) { Write-Host "You selected the directory: $folder" }
else { "You did not select a directory." }

希望有帮助

p.s。有关[System.Environment+SpecialFolder]的枚举值，请参见Environment.SpecialFolder Enum

询问用户要保存的文件路径
