Cross-merging various document streams to PDF

There may also be situations when it is necessary to combine different types of streams into PDF. In this case, you can use the example below:

string filePath1 = "c:/sample1.docx";
string filePath2 = "c:/sample2.pptx";

MemoryStream memoryStream1 = new MemoryStream();
using (FileStream fileStream1 = File.OpenRead(filePath1))
{
    fileStream1.CopyTo(memoryStream1);
}

MemoryStream memoryStream2 = new MemoryStream();
using (FileStream fileStream2 = File.OpenRead(filePath2))
{
    fileStream2.CopyTo(memoryStream2);
}

// Init Load options with defined FileTypes
LoadOptions loadOptions = new LoadOptions(FileType.DOCX, FileType.PDF);

// Load the source DOCX stream as PDF
using (Merger merger = new Merger(memoryStream1, loadOptions))
{
    // Define join options with PPTX file type
    JoinOptions joinOptions = new JoinOptions(FileType.PPTX);
    // Add another PPTX stream to merge
    merger.Join(memoryStream2, joinOptions);
    // Merge document streams and save PDF result
    merger.Save(@"c:\merged.pdf");
}
