Concatinate multiple PDF files into one file

Aspose.PDF Product Family
1

Hi There,
We have a licensed Aspose product .

I was working on a new enhancement where i need to concatinate multiple pdf files into one file .

here the work flow may contain just one pdf file or multiple file , is there a dynamic way irrespective of the uploaded documents count where i can merge them in to one pdf file .

I would really appreciate your help , a code sample would be awesome .

I saw few samples online but they are not dynamic .

Thanks
Anil

Hi Anil,


Thanks for contacting support.

The Document class can be used to concatenate PDF files and once you have merged certain number of files, you can save the output in Stream instance and when you have some more documents to concatenate, you can instantiate Document object through same Stream instance and concatenate new files with already merged output. For more information, please visit Concatenate PDF Files

In case you still face any issue or you have any further query, please feel free to contact.

Hi Anil,


Thanks for your inquiry. You can create a list of your uploaded documents and concatenate them dynamically. Please check following sample code snippet, you can change it accordingly. Hopefully it will help you to accomplish.

Document targetDoc = new Document();<o:p></o:p>

Document inputDoc;

List<String> inputDocs = new List<String>();

inputDocs.Add("E:/data/s2.pdf");

inputDocs.Add("E:/data/HelloWorld.pdf");

for (int i = 0; i < inputDocs.Count; i++)

{

inputDoc = new Document(inputDocs[i]);

// Add the pages of the source documents to the target document

targetDoc.Pages.Add(inputDoc.Pages);

}

targetDoc.Save(myDir + "merged.pdf");


Please feel free to contact us for any further assistance.
