如何在 .NET 中自动存储Batch PDF 压缩

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

string inputDir = @"C:\Documents\ToCompress";
string outputDir = @"C:\Documents\Compressed";
Directory.CreateDirectory(outputDir);

string[] pdfFiles = Directory.GetFiles(inputDir, "*.pdf");
int processed = 0;

foreach (var pdfFile in pdfFiles)
{
    string fileName = Path.GetFileName(pdfFile);
    string outputFile = Path.Combine(outputDir, fileName);

    var optimizer = new Optimizer();
    var options = new OptimizeOptions();
    options.AddInput(new FileDataSource(pdfFile));
    options.AddOutput(new FileDataSource(outputFile));

    optimizer.Process(options);
    processed++;
    Console.WriteLine($"Compressed: {fileName}");
}

Console.WriteLine($"Total PDFs compressed: {processed}");

long originalSize = new FileInfo(pdfFile).Length;
long compressedSize = new FileInfo(outputFile).Length;
Console.WriteLine($"{fileName},Original: {originalSize},Compressed: {compressedSize}");
