我从IEEE Xplore下载了大量(数千)pdf文件。
文件名只包含文件的文章号。例如
6215021. pdf
现在如果你访问
http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=6215021你可以找到关于这篇文章的所有可用信息。
如果你检查网站源代码，你可以找到下面的部分:

我想重命名我的文件为"firstpage - citation_title.pdf"
我的编程技能有限(只有一些C语言，没有解析的线索)，所以我指望你的帮助。
提前感谢大家!
您可以使用iTextSharp库编译以下c#代码。它根据PDF文件的元数据重命名目录中的所有PDF文件，包括它们的主题或标题。
using System.IO;
using iTextSharp.text.pdf;
namespace BatchRename
{
class Program
{
private static string getTitle(PdfReader reader)
{
string title;
reader.Info.TryGetValue("Title", out title); // Reading PDF file's meta data
return string.IsNullOrWhiteSpace(title) ? string.Empty : title.Trim();
}
private static string getSubject(PdfReader reader)
{
string subject;
reader.Info.TryGetValue("Subject", out subject); // Reading PDF file's meta data
return string.IsNullOrWhiteSpace(subject) ? string.Empty : subject.Trim();
}
static void Main(string[] args)
{
var dir = @"D:Prog1390iTextSharpTestsBatchRenamebinRelease";
if (!dir.EndsWith(@""))
dir = dir + @"";
foreach (var file in Directory.GetFiles(dir, "*.pdf"))
{
var reader = new PdfReader(file);
var title = getTitle(reader);
var subject = getSubject(reader);
reader.Close();
string newFile = string.Empty;
if (!string.IsNullOrWhiteSpace(title))
{
newFile = dir + title + ".pdf";
}
else if (!string.IsNullOrWhiteSpace(subject))
{
newFile = dir + subject + ".pdf";
}
if (!string.IsNullOrWhiteSpace(newFile))
File.Move(file, newFile);
}
}
}
}

This is a simple code to rename the paper based on the ORIGINAL FILENAME and their website.
Your are free to use this code, but don't blame me for the error.
I am not writing any documentation, so please read my mind in this code.
USE ON YOUR OWN RISK *evil smirk*

batchRename(workingdir, IEEE)
此代码适用于IEEE和Science Direct文章。你可以把你的文章放在workingdir。当然，您可以将workingdir的值更改为您自己的文件夹。
在该代码中，我重命名文件夹C:UsersdataqDownloadspaper中的IEEE文章。如果您想重命名Science Direct文章，您必须将batchRename(workingdir, IEEE)更改为batchRename(workingdir, SCIENCEDIRECT)
你必须确保文章的文件名是原创的(IEEE的原始文章看起来像这样:06089032.pdf, Science Direct的文章看起来像这样:1-s2.0-0031320375900217-main.pdf)
我不能保证这些工具可以很好地工作，所以使用它你自己承担风险。
