Question

如何将所有PDF的总页数值输入到文件夹中？我还想将输出写入.txt文件。

因此，我需要知道如何获取所有PDF页面的数量以及将所有页码和PDF名称放入列中的方法。

我会输出这样的输出：

PDF file name          Number of page
-------------------------------------
firstpdffile           30 pages
secondpdffile          25 pages
thirdpdffile           10 pages
fourthpdffile           5 pages
-------------------------------------
Total                  70 pages

Option Explicit

Private Function getPdfPgCnt(ByVal sPath) 'Returns page count of file on passed path
    Dim strTStr

    With CreateObject("Adodb.Stream")
        .Open
        .Charset = "x-ansi"
        .LoadFromFile sPath
        strTStr = .ReadText(-1)
    End With

    With (New RegExp)
        .Pattern = "Type\s*/Page[^s]"
        .IgnoreCase = True
        .Global = True
        getPdfPgCnt = .Execute(strTStr).Count
    End With

    If getPdfPgCnt = 0 Then getPdfPgCnt = 1
End Function

'--------------------------------
Dim oFso, iFile
Set oFso = CreateObject("Scripting.FileSystemObject")

'enumerating pdf files in vbs's base directory
For Each iFile In oFso.getFolder(oFso.GetParentFolderName(WScript.ScriptFullName)).Files
    If LCase(oFso.GetExtensionName(iFile)) = "pdf" Then WScript.Echo iFile & " has "& getPdfPgCnt(iFile)&" pages."
Next
Set oFso = Nothing

我使用此.bat文件来运行脚本

@echo off
color 0A

@set currentdir="%cd%"

title PDF page counter

del temp1.txt
del temp2.txt
del temp3.txt
del output.txt

cscript pdfpagecount.vbs > temp1.txt

BatchSubstitute.bat "%cd%" "" temp1.txt > temp2.txt & BatchSubstitute.bat "\" "" temp2.txt > temp3.txt & Type temp3.txt | findstr /I /V /C:"Microsoft" >>output.txt & del temp1.txt & del temp2.txt & del temp3.txt

exit

@echo off

努力专注于

表（页眉，正文，页脚），如控制台脚本的输出
总结价值

你需要什么

.NET sprintf like formatting（class cFormat）
sum变量在循环之前初始化为0，在循环中添加，在循环之后输出/使用

在代码中：
