Aspose.PDF 조합을 사용하여 여러 PDF를 결합하는 방법 .NET

PM> Install-Package Aspose.PDF

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

string inputPath1 = @"C:\Samples\file1.pdf";
string inputPath2 = @"C:\Samples\file2.pdf";
string outputPath = @"C:\Samples\merged.pdf";

var merger = new Merger();
var options = new MergeOptions();
options.AddInput(new FileDataSource(inputPath1));
options.AddInput(new FileDataSource(inputPath2));
options.AddOutput(new FileDataSource(outputPath));
merger.Process(options);

string[] pdfFiles = Directory.GetFiles(@"C:\Samples\MergeQueue", "*.pdf");
var merger = new Merger();
var options = new MergeOptions();
foreach (var file in pdfFiles)
{
    options.AddInput(new FileDataSource(file));
}
options.AddOutput(new FileDataSource(outputPath));
merger.Process(options);

// Example assumes that password is managed during loading (via Aspose.PDF for .NET, if needed)
// If merging fails, check file permissions and passwords.

// For simple merge, all pages are included by default.
// For page range selection, use pre-split PDFs as input or programmatically extract required pages first.
