Request.Files in ASP.NET CORE
ajax, asp.net, asp.net-core, file, upload
Solution
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;
}
}
}
Problem
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?
