asp.net核心使用ajax发送表单文件，我无法在控制器中归档文件

Question

asp.net核心2.2

model.file或其他文件。不包含文件。每次为null。嵌套的ajax或运行顺序ajax。

我想更新个人资料。我能。当文件上传到工作中时，我爆炸了。

使用不同的ajax查询进行文件上传和用户更新？我应该以不同的方法期待不同的Ajax查询吗？还是在单个ajax查询中处理？

抱歉，我的英语不好。

控制器：

public IActionResult UpdateProfile(ProfileModel model, IFormFile file)
        {            
            var result = userOperation.UpdateUser(model).Result;
            if (result.Succeeded)
            {
                return Ok();
            }
            else
            {
                return BadRequest();
            }

        }

ProfileModel：

public class ProfileModel
    {
        public string UserId { get; set; }
        public string username { get; set; }
        public string Name { get; set; }
        public string SurName { get; set; }
        public string ProfilePhoto { get; set; }
        public IFormFile file { get; set; }
    }

Jquery：

var isim = $('#name');
var soyisim = $('#surname');
var menu = $('#navInside');
var cikis = $('#logout');
var updateCikis = $('#exit');
var update = $('#update');
var goUpdate = $('#goUpdate');
var kaydet = $('#kaydet');
var dosya = $('input[type=file]');
var username2 = $('#username').val();
kaydet.click(function (event) {
                event.preventDefault();
                $.ajax({
                    url: '/Registered/UpdateProfile',
                    data: { Name: isim.val(), SurName: soyisim.val(), username: '@User.Identity.Name' },
                    type: 'POST',
                    success: function (result) {
                            console.log('basarili güncelleme');
                            var formData = new FormData();
                            formData.append('file', dosya[0].files[0].name);
                            console.log(dosya[0].files[0].name);
                            console.log(JSON.stringify(dosya[0].files[0]));
                            $.ajax({
                                url: '/Registered/UpdateProfile',
                                data: { Name: isim.val(), SurName: soyisim.val(), username: '@User.Identity.Name', file: formData },
                                processData: false,
                                contentType: false,
                                type: 'POST',
                                success: function(){
                                    alert('foto da gittiii');
                                }
                            });
                    }
                });
