Request.Files in ASP.NET CORE

Question

I am trying to upload files using aspnet core using ajax request . In previous versions of .net i used to handle this using

 foreach (string fileName in Request.Files)             {                 HttpPostedFileBase file = Request.Files[fileName];                 //Save file content goes here                  fName = file.FileName;      (...) 

but now its showing error at request.files how can i get it to work ? i searched and found that httppostedfile has been changed to iformfile but how to handle request.files?

This is working code from a recent project. Data has been moved from Request.Files to Request.Form.Files. In case you need to convert stream to byte array - this is the only implementation that worked for me. Others would return empty array.

using System.IO; var filePath = Path.GetTempFileName(); foreach (var formFile in Request.Form.Files) {    if (formFile.Length > 0)    {       using (var inputStream = new FileStream(filePath, FileMode.Create))       {          // read file to stream          await formFile.CopyToAsync(inputStream);          // stream to byte array          byte[] array = new byte[inputStream.Length];          inputStream.Seek(0, SeekOrigin.Begin);          inputStream.Read(array, 0, array.Length);          // get file name          string fName = formFile.FileName;       }    } }
