What is good practice for sending image files to the IIS web server?

Question

Hello,

I wrote an Office AddIn that photographs an Excel sheet range and transfers the image to an ASP.NET WebAPI on our internal IIS server. I also added MVC functionality to the API to allow the image to be displayed in a View.

But I'm unsure whether a WebAPI is a good choice for this. Everything works as it should and the purpose of the whole development is to set up the image as a 'standard website' for the employees - i.e. the page is set as default via GPO.

How would you do that, or what would be good practice here? I think a WebAPI does involve more security effort, and since it doesn't even support views by default, I'm not sure whether this would be a good solution for this simple case.

Hi @Dean Marinov,

You can upload images from a server folder using ASP.NET MVC.

You can follow this article to upload image in MVC5 application. Upload Images on Server Folder Using ASP.NET MVC

Refer to the following code:

[HttpPost]
        public ActionResult Upload(HttpPostedFileBase file)
        {
            Uri requestUri = HttpContext.Request.Url;
            string baseUrl = requestUri.Scheme + Uri.SchemeDelimiter + requestUri.Host + (requestUri.IsDefaultPort ? "" : ":" + requestUri.Port);
            if (ModelState.IsValid)
            {
                try
                {
                    if (file != null)
                    {
                        string path = Path.Combine(Server.MapPath("~/Images"), Path.GetFileName(file.FileName));
                        file.SaveAs(path);
                    }
                    string link = baseUrl + "/Images/" + file.FileName;
                    ViewBag.FileStatus = "File uploaded successfully.";
                    //Return the url of image
                    ViewBag.FileLink = link;
                }
                catch (Exception e)
                {
                    ViewBag.FileStatus = "Error while file uploading. Error message is "+e.Message;

                }
            }
            return View("Index");
        }

Index.cshtml add this to show url.

<div class="col-md-offset-2 col-md-10 text-success">
        @ViewBag.FileLink
</div>

Don't forget to add a folder named Images to store images. After publishing, you also need to add it in published folder, otherwise error message will show that cannot find folder.

It works well.

Best regards,
Lan Huang
