How to save image/video on server with or without web api in MVC?


I have a website that shows galleries, users can upload their own content from the web (by entering a URL) or by uploading a picture from their computer.

I am storing the URL in the database which works fine for the first case but I need to figure out where to store the actual images if a user uploads pictures from their local computer.

Is there any recommendation here or best practice on where should I store these and how can i store it on server?

help me! thank you very much

You can follow these steps, for uploading user pictures on the server

  1. Create a folder("Upload") on your server or on your project inside "Images" folder
  2. on View create a form with FormMethod.Post and enctype = "multipart/form-data"
    @using (Html.BeginForm("Action", "Controller", FormMethod.Post, new { enctype = "multipart/form-data" })
    {
    
     <input type="file" name="ImageFile" id="ImageFile" />
    
    <input type="submit" value="Submit" id="Submit" />
    }?
  3. On the controller side, create a C# to upload and save file on server and URL in database
            [HttpPost]
            public ActionResult ImageUpload()
            {
                if (Request.Files.Count > 0)
                {
                    try
                    {
                        //  Get all files from Request object  
                        HttpFileCollectionBase files = Request.Files;
                        var savedurl = "";
                        for (int i = 0; i < files.Count; i++)
                        {
                            //string path = AppDomain.CurrentDomain.BaseDirectory + "Uploads/";  
                            //string filename = Path.GetFileName(Request.Files[i].FileName);  
    
                            HttpPostedFileBase file = files[i];
                            string fname;
    
                            // Checking for Internet Explorer  
                            if (Request.Browser.Browser.ToUpper() == "IE" || Request.Browser.Browser.ToUpper() == "INTERNETEXPLORER")
                            {
                                string[] testfiles = file.FileName.Split(new char[] { '\\' });
                                fname = testfiles[testfiles.Length - 1];
                            }
                            else
                            {
                                fname = file.FileName;
                            }
                            string subPath = "~/Images/Upload/"; // your code goes here
    
                            bool exists = System.IO.Directory.Exists(Server.MapPath("~/Images/Upload/"));
    
                            if (!exists)
                            { System.IO.Directory.CreateDirectory(Server.MapPath("~/Images/Upload/")); }
    
    
                            // Get the complete folder path and store the file inside it.  
                            fname = Path.Combine(Server.MapPath("~/Images/Upload/"), fname);
                            savedurl = "/Images/Upload/" + file.FileName;
    
                             //save this URL in database here
    
                            //save file on server
    
                            file.SaveAs(fname);
                        }
                        // Returns message that successfully uploaded  
                        return Json(new { MSG="File Uploaded Successfully!" , SAvedUrl= savedurl },JsonRequestBehavior.AllowGet);
                    }
                    catch (Exception ex)
                    {
                        return View("_Error");
                    }
                }
                else
                {
                    return View("_Error");
                }
            }
