How to Combine PDF Documents

The following steps and C# sample code illustrate combining multiple PDF documents into a single PDF.

Steps for Combining PDF Documents

1. Create a MergeDocument object by passing the first PDF file to the constructor.
2. Use the MergeDocument instance's Append method to add the second PDF document.
3. Use the Append method a third time to append another PDF document. Also pass the 1, and 2 page parameters to the Append method.
4. Add the Draw method to save the merged PDF.

Sample Code - C#

MergeDocument document = new MergeDocument("DocumentA.pdf");
document.Append("DocumentB.pdf);
document.Append("DocumentC.pdf, 1, 2);
document.Draw("Output.pdf");
