File upload in asp net core mvc

[@amitghosh1983]

There is a breaking change in core 3.1 for the IForm class, above is Core 2.1. make sure you add asp-action="Create" enctype="multipart/form-data" to the Create View to populate the path. After that small change, It's working like a charm for me. Kudos to Venkat, you rock!!

[@Nermin913]

Awesome video. Very informative, thank you! Just a quick comment: When you use the CopyTo() method from the IFormFile interface, you instantiate a new filestream object as the parameter, resulting in you not closing the filestream object. This will give SystemIO exceptions later on if you want to delete those images from the server. A simple fix is just to instantiate the filestream object before using the CopyTo() method, and thereafter calling the Close() method: FileStream fs = new FileStream(filePath, FileMode.Create); model.Image.CopyTo(fs); fs.Close();

[@admiremhlaba1192]

Thank you for the pointer, alternatively you could achieve the same by doing this using(FileStream fs = new FileStream(filePath, FileMode.Create)) { model.Image.CopyTo(fs); }

[@nikhilchoubisa8134]

You guys saved me. I was uploading an excel file using reference of this video and later while reading that file I got following error : "the process cannot access the file because it is being used by another process". After applying this help my code worked. Thank you guys. :)

That's what i am wondering from very first day....And if we come to know we can also do magic.

[@danishmalak9221]

From microsoft asp.net core documentations

[@Abhimanyukumar-vb8bz]

we can also use "col-sm-4" class wrapping div element with class "card -m-3" to restrict 3 columns in one row instead of hardcoding the style attribute with min and max-width like this : @foreach (var Employee in Model) { var photoPath = "~/Images/" + (Employee.PhotoPath ?? "banner1.jpg"); @Employee.Name View Edit Delete }

[@alensgallery]

When I get to 13:00 i need to create a fileName and use GetFilename and include it in a variable because filename property returns the complete path including the filename and the extension. Because of the filename appending, the final image path ends up having more than just the name appended. Am I missing something?? Here is the code change string fileName = Path.GetFileName(model.Photo.FileName); uniqueFileName = Guid.NewGuid().ToString() + "_" + fileName;

[@northernouthouse]

Yes, I had the exact same error and your recommended code fixed the issue. Thanks!

[@AmirKMilbes]

Instead of writing inline CSS, you should have used class=row and col-md-4 as in example below. 4 + 4 + 4 = 12 -- the bootstrap 12-rows model. But, you are still my great teacher. Thank you for the videos. @foreach (var employee in Model) { var photoPath = "~/images/" + employee.PhotoPath; @employee.Name View Edit Delete }

[@dannybradley9346]

I am attempting to use the newest VS2019 and .net core versions. The tutorials are excellent, and I was able to make it all work until the "File upload in asp net core mvc" tutorial; it uses a now-deprecated IHostingEnvironment. At that point, VS recommends IWebHostEnvironment. I tried many things and could not get IWebHostEnvironment to work without errors: "Model bound complex types must not be abstract or value types and must have a parameterless constructor. Alternatively, give the 'hostingEnvironment' parameter a non-null default value.". How to make it work?

[@hughcoleman9400]

I may be using a slightly older version VS2019 and .NET core and this may be just a work around, but when I encountered that error in another tutorial I used the [obsolete] attribute above the class and it worked

Instead of creating new class EmployeeCreateViewModel it's better to add to existing class Employee two properties: public string PhotoPath { get; set; } [NotMapped] public IFormFile Photo { get; set; } So with Photo property we work on View and we don't have this column in DB table Employee (by owing to the attribute NotMapped: you also must add namespace System.ComponentModel.DataAnnotations.Schema). By means of PhotoPath property we save file path in DB. What do you think?

If you get null IFormFile then try to use: HttpContext.Request.Form.Files[0] it will fix your problem. I spent many hours to fix this issue. So, create a variable like this: var getImgFile = HttpContext.Request.Form.Files[0]; and instead of using model.Photo use getImgFile. My whole code: [HttpPost] public IActionResult Create(Gpu gpuData) { if (ModelState.IsValid) { var getImgFile = HttpContext.Request.Form.Files[0]; int maxId = GpuMockData.GpuCollection.Max(g => g.Id); gpuData.Id = maxId + 1; ///Check if image is null or not string uniqueImageName = null; if(getImgFile != null) { string uploadsFolder = Path.Combine(_hostingEnvironment.WebRootPath, "images"); uniqueImageName = Guid.NewGuid().ToString() + "_" + getImgFile.FileName; string filePath = Path.Combine(uploadsFolder, uniqueImageName); getImgFile.CopyTo(new FileStream(filePath, FileMode.Create)); } gpuData.Image = uniqueImageName; GpuMockData.GpuCollection.Add(gpuData); return RedirectToAction("Index", "Home"); } return View(); }
