我需要从视图和控制器中获取照片，但总是空的

我需要从视图和控制器中获取照片，但是它始终为空。我尝试下载jpeg。

HTML

<div class="form-group">
        <label asp-for="Avatar"></label><br />
        <input asp-for="Avatar" multiple>
    </div>

控制器

public async Task<IActionResult> Register(RegisterViewModel model)
        {
            if (ModelState.IsValid)
            {
                User user = new User { Email = model.Email, FirstName = model.FirstName, LastName = model.LastName, UserName = model.Email, Address = model.Address };

                using (var memoryStream = new MemoryStream())
                {
                    await model.Avatar.CopyToAsync(memoryStream);
                    user.Avatar = memoryStream.ToArray();
                }
                var _result = await _userManager.CreateAsync(user, model.Password);
                if (_result.Succeeded)
                {

                    await _signInManager.SignInAsync(user, true);
                    //IdentityResult result = await _userManager.AddToRoleAsync(user, "User");

                    await _userRepository.SendConfirmEmailMessage(user.Email);


                    return RedirectToAction("Index", "Home");
                }
                else
                {
                    foreach (var error in _result.Errors)
                    {
                        ModelState.AddModelError(string.Empty, error.Description);
                    }
                }

            }
            return View(model);
        }

RegisterViewModel

public IFormFile Avatar { get; set; }

用户

public byte[] Avatar { get; set; }

RegisterViewModel

[FromForm]
public IFormFile Avatar { get; set; }

并删除ApiController属性
