将Json对象和FormData(文件)发送到带有参数MVC的控制器

我正在尝试创建注册页面。我希望用户在注册时上传图像。我在控制器上创建了一个带有两个参数的动作。一个是模型，另一个是HttpPostFileBase对象。但我不能同时传递这两个物体。我尝试了很多方法，但我不能找到它。谢谢。

单击register调用register()方法。

function Register() {

    var team = { id: $("#team").val() }
    var account =
    {
        eMailAddress: $("#eMailAddress").val(),
        userName: $("#userName").val(),
        password: $("#password").val(),
        password2: $("#password2").val(),
        firstName: $("#firstName").val(),
        lastName: $("#lastName").val(),
        gender: $("#gender").val(),
        team: team,
        birthday: $("#birthday").val(),
        phoneAreaCode: $("#phoneAreaCode").val(),
        phoneLocalNumber: $("#phoneLocalNumber").val()
    }
    var imageFile = $('#image').get(0).files[0];

    var data = new FormData();
    data.append("image", imageFile);
    data.append('account', account);
    console.log(typeof data);
    $.ajax
    ({
        url: "/Registration/Register",
        type: "POST",
        data: data,
        contentType: false,
        processData: false,
        success: function (response) {
            $("#message").hide();
            $("#message").empty();
            if (response.isSucceeded) {
                window.location.replace("/Login/Login");
            }
            else {
                $.each(response.errors, function (i, error) {
                    $("#message").append(error + "<br>");
                });
                $("#message").fadeIn();
            }

        }
    });
}

还有Controller Action

    [HttpPost]
    public ActionResult Register( HttpPostedFileBase image,Account account )
        {
        account.team = serviceFactory.Run<GetTeamByIdResponse>(x => x.GetTeamById(new GetTeamByIdRequest(account.team.id))).team;
        account.GenerateVerificationCode();
        CreateAccountRequest request = new CreateAccountRequest();
        request.account = account;
        request.image = image;
        request.server = Server;
        CreateAccountResponse response = serviceFactory.Run<CreateAccountResponse>(x => x.CreateAccount(request));
        if (response.isSucceeded)
        {
            //toDo
        }
        return Json(response);
    }
