如何在 .NET 中自动分解 PDF 文件

using Aspose.Pdf.Plugins;
using System.IO;

string inputFolder = @"C:\Archive\PDFs";
string outputFolder = @"C:\Archive\Split";
Directory.CreateDirectory(outputFolder);

string[] pdfFiles = Directory.GetFiles(inputFolder, "*.pdf");

foreach (var pdfFile in pdfFiles)
{
    string baseName = Path.GetFileNameWithoutExtension(pdfFile);
    // Example: Determine page count (using Aspose.PDF.Document, or plugin API if available)
    int pageCount = /* Get page count for pdfFile */;
    var splitter = new Splitter();
    var splitOptions = new SplitOptions();
    splitOptions.AddInput(new FileDataSource(pdfFile));
    for (int i = 1; i <= pageCount; i++)
    {
        string outPath = Path.Combine(outputFolder, $"{baseName}_Page_{i}.pdf");
        splitOptions.AddOutput(new FileDataSource(outPath));
    }
    splitter.Process(splitOptions);
    Console.WriteLine($"Split {pdfFile} into {pageCount} pages.");
}
