httppostedfilebase

I understand the relationship between HttpPostedFileBase and HttpPostedFileWrapper , in terms of the need for both of them (i.e. in unit testing/mocking). But why, when I put a breakpoint on the return for HttpPostedFileBase , does it show it as HttpPostedFileWrapper ? Furthermore, HttpPostedFileBase doesn't implement the ContentType property. So why does it return a value when my code only references HttpPostedFileBase , and not HttpPostedFileWrapper ? What kind of trickery is this? Edit #1: Thanks for the great reply @lawliet29. I have written out the structure as suggested. public sealed

I am using ASP.NET MVC and I've an action that uploads the file. The file is being uploaded properly. But I want width and height of the image. I think I need to convert the HttpPostedFileBase to Image first and then proceed. How do I do that? And please let me know if there is another better way to get the width and height of the image. I use Image.FromStream to as follows: Image.FromStream(httpPostedFileBase.InputStream, true, true) Note that the returned Image is IDisposable . You'll need a reference to System.Drawing.dll for this to work, and Image is in the System.Drawing namespace.

I want to test the following line of code: ... Bitmap uploadedPicture = Bitmap.FromStream(model.Picture.InputStream) as Bitmap; ... Picture is a property in my model type HttpPostedFileBase. So I would like to mock a HttpPostedFileBase property for unit-testing: model.Picture = new Mock<HttpPostedFileBase>().Object; No problem at all. Now I have to mock the InputStream, otherwise it's null: model.Picture.InputStream = new Mock<Stream>().Object; This isn't working as the InputStream is read-only (hasn't a setter method): public virtual Stream InputStream { get; } Is there a good and clean way

I am attempting to upload an image using MVC 6 ; however, I am not able to find the class HttpPostedFileBase . I have checked the GitHub and did not have any luck. Does anyone know the correct way to upload a file in MVC6 ? MVC 6 used another mechanism to upload files. You can get more examples on GitHub or other sources . Just use IFormFile as a parameter of your action or a collection of files or IFormFileCollection if you want upload few files in the same time: public async Task<IActionResult> UploadSingle(IFormFile file) { FileDetails fileDetails; using (var reader = new StreamReader(file
