Best way to generate and return large XML files without saving locally? (RunBaseBatch)

Hello everybody

I am currently generating an XML file inside X++ and I save it locally before streaming it to the user.

Here is the code:

XmlDocument xmlDoc;

xmlFileName = _nameFile+'.xml'; //
xmlFilePath = System.IO.Path::GetTempPath() + xmlFileName;

xmlDoc.save(xmlFilePath);

System.IO.MemoryStream memoryStream;

memoryStream = new System.IO.MemoryStream(System.IO.File::ReadAllBytes(xmlFilePath));

File::SendFileToUser(memoryStream, xmlFilename);

This works, but:

Problem

In the future, the generated XML files may become very large.

Saving large files on the local disk is not the best option.

My Question

Is there an alternative solution that allows me to:

Generate and return the XML without saving it to a local file,
Or store it somewhere safer
And still download it to the user when needed?

Thanks for the help.

Hi,

Can you please clarify if your question is related to Dynamics AX (2012 or before) or Dynamics 365 F&O? You used both tags, which is contradictory. Most likely your question is about F&O, but please confirm.

Anyway, what is the reason to save it locally? You can directly get the XML content in a memory stream.

What is the best option depends on what you do with the XML document. Unfortunately, you gave us no description and your code snippet is completely missing this part.

If you want to keep using XmlDocument class, notice that it's a wrapper around System.Xml.XmlDocument, which has a method for saving to a Stream. You can create an extension of XmlDocument and a method exposing document.Save().

Nevertheless the idea that saving large files on disk sounds very strange to me. This is what disks are for. What you should be more concerned about is keeping large files in RAM, which is normally much smaller than disk space.
