Vbscript列出文件夹和子文件夹中的所有PDF文件

好吧，这是我的代码，但我无法使用 objFile.Extension 过滤列表，我确信这很愚蠢

Set objFSO = CreateObject("Scripting.FileSystemObject")
objStartFolder = "C:\dev"

Set objFolder = objFSO.GetFolder(objStartFolder)
Wscript.Echo objFolder.Path

Set colFiles = objFolder.Files

For Each objFile in colFiles
If objFile.Extension = "PDF" Then
    Wscript.Echo objFile.Name
    End If
Next
Wscript.Echo

ShowSubfolders objFSO.GetFolder(objStartFolder)

Sub ShowSubFolders(Folder)
    For Each Subfolder in Folder.SubFolders
        Wscript.Echo Subfolder.Path
        Set objFolder = objFSO.GetFolder(Subfolder.Path)
        Set colFiles = objFolder.Files
        For Each objFile in colFiles
            Wscript.Echo objFile.Name
        Next
        Wscript.Echo
        ShowSubFolders Subfolder
    Next
End Sub

运行时返回错误

(11, 1) Microsoft VBScript 运行时错误：对象不支持此 属性或方法：'objFile.Extension'

你会想要使用获取扩展名 http://msdn.microsoft.com/en-us/library/x0fxha2a%28v=VS.85%29.aspxFileSystemObject 对象上的方法。

Set x = CreateObject("scripting.filesystemobject")
WScript.Echo x.GetExtensionName("foo.pdf")

在你的例子中，尝试使用这个

For Each objFile in colFiles
    If UCase(objFSO.GetExtensionName(objFile.name)) = "PDF" Then
        Wscript.Echo objFile.Name
    End If
Next
