Receive file and other form data together in ASP.NET Core Web API (boundary based request parsing)

I had the similar issue and I solved the problem by using [FromForm] attribute and FileUploadModelView in the function as follow:

[HttpPost][Route("upload")]public async Task<IActionResult> Upload([FromForm] FileUploadViewModel model, [FromForm] string member_code){    var file = model.File;        // ...}

This is a quick solution for anyone who is facing the same issue:

You will use ajax to send the following formData

let formData: FormData;formData = new FormData();formData.append('imageFile', imageFile);formData.append('name', name);

Then you will receive it in your controller like this:

public string Post(IFormCollection data, IFormFile imageFile)

Then you will access the data as you do normally:

var name = data["name"];

In HomeController.cs

using Microsoft.AspNetCore.Hosting;.......private IHostingEnvironment _environment;public HomeController(IHostingEnvironment environment){    _environment = environment;}[HttpPost][ValidateAntiForgeryToken]        public IActionResult Index(IFormCollection formdata){ var files = HttpContext.Request.Form.Files; foreach (var file in files) {     var uploads = Path.Combine(_environment.WebRootPath, "Images");     if (file.Length > 0)     {        string FileName = Guid.NewGuid(); // Give file name        using (var fileStream = new FileStream(Path.Combine(uploads, FileName), FileMode.Create))        {            file.CopyToAsync(fileStream);        }            }  }}

In view - Index.cshtml

<form method="post" enctype="multipart/form-data" > .....</form>

You can try this code.

Thanks!!
