Shell32.Folder.GetDetailsOf(..,..)有哪些选项？（注：此为一个提问标题，无需回答）

我看到一些使用GetDetailsOf()的答案来获取关于shell项目的详细信息，但数字总是神奇的数字。

我查看了FolderItem和GetDetailsOf文档，但没有发现有用的信息。(后者中的列表并不是所有内容。他们没有涵盖“描述”、“作者”，也没有回收站删除日期...)

是否有一种方法可以返回一个项目的可能选项？它在哪里列出？

不确定这是否有帮助 http://archive.msdn.microsoft.com/WindowsAPICodePack 你看过这个吗？https://dev59.com/J3VC5IYBdhLWcg3wqzHV - paparazzo
@Blam 虽然我想避免使用 Windows API Codepack 这个额外的依赖项，但第二个链接似乎非常有帮助。我不知道为什么在搜索时没有看到它。谢谢。 - ispiro

@Blam IEnumerable - ?? 我没有提到过。关于你的另一点 - 我 不想要可以使用FolderInfo检索的简单属性 - 我想要那些不能检索的属性。 - ispiro

语言并不重要，因为我们所谈论的功能是 Windows Shell 的 COM 接口和类的一部分。从所有语言访问它都是相同的。无论如何，Shell 扩展可以添加具有自己列的新文件夹类型。实际上，打印机文件夹、回收站等都是“只是”另一个扩展。无论如何，Windows 属性系统在此处有详细描述，包括注册新属性或请求特定属性的 shell 项的方法。 - Panagiotis Kanavos

@PanagiotisKanavos - 访问Shell API有许多方法，语言在某种程度上起着作用，因为1）一些Shell接口针对脚本语言（如FolderItem），而其他接口则不是（IShellFolder），2）在.NET中，您无法访问帮助编程Shell的TLB（最好的选择是Blam提到的Windows API Code Pack）。在C++中，编写Shell程序要容易得多。 - Simon Mourier

我是偶然间发现的。如果你将null传递给GetDetailsOf，它会响应列名。例如，使用cscript执行以下JScript：

var shellapp = WScript.CreateObject("Shell.Application");
var folder = shellapp.NameSpace("D:\\");
for (var j = 0; j < 0xFFFF; j++) {
    detail = folder.GetDetailsOf(null, j);
    if (!detail) {
        break;
    }
    WScript.Echo("[" + j + "] = " + detail);
}

在我的 Windows 10 系统上，这将输出：

[0] = Name

这与Windows 2000截然不同，详见检索扩展文件属性。顺便说一下，如果您传递一个不同的NameSpace，您将获得不同的属性。在我的示例中，我正在查询驱动器D:上的文件可用属性，这可能因其格式而异。

我进行了Windows 10测试，收集了超过300个数据列。

PowerShell代码：

$objFolder = (New-Object -ComObject Shell.Application).Namespace('c:\')
for ($columnNumber = 0; $columnNumber -lt 500; ++$columnNumber) 
{ 
    $columnName = $objFolder.GetDetailsOf($objFolder.Items, $columnNumber) 
    if ($columnName)
    {
        Write-Output "$(([string]$columnNumber).PadLeft(3)) $columnName"
    }
}

一个VBA函数可以完成这项工作。 需要使用Microsoft Scripting Runtime和Microsoft Shell Controls And Automation。
Function Propriétés(Chemin As String, Fichier As String)
    'Chemin représente le chemin du dossier où se trouve le fichier MP3
    'Fichier représente le nom du fichier mp3 avec l'extension
    Dim Shl As New Shell32.Shell
    Dim Rep As Shell32.Folder
    Dim fich As Shell32.FolderItem

    Dim aPropName() As String, i As Integer
    Set Shl = CreateObject("Shell.Application")
    Set Rep = Shl.Namespace(Chemin)
    Set fich = Rep.Items.Item(Fichier)
    For i = 0 To 1000
        ReDim Preserve aPropName(i)
        aPropName(i) = Format(i, "000 : ") & Rep.GetDetailsOf(Null, i)
        If Len(Rep.GetDetailsOf(Null, i)) = 0 Then
            ReDim Preserve aPropName(i - 1)
            Exit For
        End If
    Next
    ' Create ouput file
    Dim Fso, MyFile
    Set Fso = CreateObject("Scripting.FileSystemObject")
    Set MyFile = Fso.CreateTextFile(Chemin & "\Prop Liste - " & Fichier & ".txt", True)
    MyFile.Write Join(aPropName, Chr(13))
    MyFile.Close
    Set Fso = Nothing
    Set MyFile = Nothing
    Propriétés = aPropName

    Set Shl = Nothing
    Set Rep = Nothing
    Set fich = Nothing
End Function

太好了，这个Get-Metadataflags让我得到了文件版本的索引，并避免了本地化问题，因为在PT-BR中它将是“Versão do Arquivo”，这很难以编程方式检索。这使我从Technet Get-FileMetadata（https://gallery.technet.microsoft.com/scriptcenter/Get-FileMetaData-3a7ddea7）派生出另一个函数，并通过找到它的索引（对于PT-BR为166），我想出了这个返回文件版本字符串的函数：

Function Get-FileVersion
{ 
    <# 
    .SYNOPSIS 
        Get-FileVersion returns metadata version information about a single file. 

    .DESCRIPTION 
        This function will return file version (or another specific attribute based on index) information about a specific file.
        It can be used to access the information stored in the filesystem. 
        Based on: Get-FileMetadata https://gallery.technet.microsoft.com/scriptcenter/Get-FileMetaData-3a7ddea7
        and Get-FileMetadataFlags https://dev59.com/vWEh5IYBdhLWcg3wdjTt#62279888
                
    .EXAMPLE 
        Get-FileVersion -File "c:\temp\image.jpg" 
        Get information about an image file. 
    #> 

    param([Parameter(Mandatory=$True)][string]$File = $(throw "Parameter -File is required.")) 

    $index = 166 #File version index (PT-BR) from Get-FileMetadataFlags (see description)

    if(!(Test-Path -Path $File)) 
    { 
        throw "File does not exist: $File" 
        Exit 1 
    } 

    $tmp = Get-ChildItem $File 
    $pathname = $tmp.DirectoryName 
    $filename = $tmp.Name 

    $shellobj = New-Object -ComObject Shell.Application 
    $folderobj = $shellobj.namespace($pathname) 
    $fileobj = $folderobj.parsename($filename) 
    
    if($folderobj.getDetailsOf($folderobj, $index) -and $folderobj.getDetailsOf($fileobj, $index))  
    { 
        $results = $($folderobj.getDetailsOf($fileobj, $index))
    } 
     
    $results 
} #function Get-FileVersion
