How to upload files with additional file data in asp.net core

Question

I am trying to upload multiple files (documents) with additional data per file. Ie. I would like to upload multiple documents like this:

[{
  documentFile: file
  documentVersion: 2,
  documentOperation: "createNew"
  ...
 },
 {
  documentFile: file2.doc
  documentVersion: 1,
  documentOperation: "createNew"
  ...
 }]

And ideally would like that information to be populated in the model but this is not a requirement.

I am using Aurelia Fetch client to send data using FormData.

Is this possible?

If your model is like:

public class Documents
{
    public IFormFile documentFile { get; set; }
    public string documentVersion { get; set; }
    public string documentOperation { get; set; }
}

You can see my test.

Action:

 [HttpPost]
    public IActionResult Demo(List<Documents> documents)
    {
        //...
    }

Send data by postman:

Result:
