Right! Thanks for your help with a succinct answer and explanation. I was getting sick of trying to decipher the correct approach from StackOverflow :blobthumbsup:

Using ref for large data types.
Hi thanks for the reply. What about if I was to pass a list containing incoming data as I am here in my GET endpoint? 
[HttpPost]
        [Route("upload")]
        public async Task<IActionResult> UploadDataAsync(List<IFormFile>? files)
        {
            if (files is not null && _env is not null)
            {
               return await _checkpoint.SaveDataToStorage(files);
            }
            return new StatusCodeResult(400);
        }
[HttpPost]
        [Route("upload")]
        public async Task<IActionResult> UploadDataAsync(List<IFormFile>? files)
        {
            if (files is not null && _env is not null)
            {
               return await _checkpoint.SaveDataToStorage(files);
            }
            return new StatusCodeResult(400);
        }
In the following function I've got 
public async Task<IActionResult> SaveDataToStorage(List<IFormFile> files)
        {
            List<IFormFile> incomingFiles = files;
            
            if (!CheckValidFileTypes(incomingFiles))
            {
                return new UnsupportedMediaTypeResult();
              (There's more going on in here , shortened it for this post)
            }
        }
public async Task<IActionResult> SaveDataToStorage(List<IFormFile> files)
        {
            List<IFormFile> incomingFiles = files;
            
            if (!CheckValidFileTypes(incomingFiles))
            {
                return new UnsupportedMediaTypeResult();
              (There's more going on in here , shortened it for this post)
            }
        }
Would it be correct to put ref in front of 
incomingFiles
incomingFiles
when calling the 
CheckValidTypes
CheckValidTypes
function or will that do a copy?

❔ Can anyone break down this one-line code for me?
Oh so it's a lamda, I see. I think I'm going to have to read up on lamdas and Actions too. Thank you for your help, you've put me on the right track. 👍

I'm not sure in this context haha. I'm under the impression => is used for lambda declaration and expression based properties. What does it mean in this context?
