Hi everybody,

I have the following method:

[Route("")]
        [HttpPost]
        public IHttpActionResult CreateMax4Sale(EditMax4SaleViewModel max4saleViewModel)
        {
            var conflicts = ChangeMax4Sale(max4saleViewModel, "Add");

            if (conflicts == 0)
            {
                return Ok(max4saleViewModel);
            }

            return ThrowError(conflicts);
        }

In the ChangeMax4Sale method I have at the bottom:

max4saleViewModel = GetModel(max4sale);

At this point when I examine max4SaleViewModel variable I can see that its Id is properly set to the new Id.

However, when I examine it back in the calling method, I see the Id is back to 0.

What am I missing here and how can I make sure that my variable is properly updated? Should I explicitly pass it by reference?

Thanks a lot in advance.

UPDATE. Adding ref keyword to the method and the call fixed the issue.
