單選按鈕值不會傳輸到模型-ASP.NETCore

我在 asp .net core 中有一個網頁，其中包含以下輸入：

@model MyProject.ViewModels.UserScoreModel 
        <div>
            <label asp-for="GivenServiceScore"></label><br />
            <input required asp-for="GivenServiceScore" type="radio" name="servScore" id="servScore" value="5" /> 5
            <input required asp-for="GivenServiceScore" type="radio" style="padding-left:15px" id="servScore" name="servScore" value="4" /> 4
            <input required asp-for="GivenServiceScore" type="radio" style="padding-left:15px" id="servScore" name="servScore" value="3" /> 3
            <input required asp-for="GivenServiceScore" type="radio" style="padding-left:15px" id="servScore" name="servScore" value="2" /> 2
            <input required asp-for="GivenServiceScore" type="radio" style="padding-left:15px" id="servScore" name="servScore" value="1" /> 1
            <span asp-validation-for="GivenServiceScore" ></span>
        </div>
        <h5 style="padding-top:15px; padding-bottom:15px">@ViewBag.CongratsMessage</h5>
        <div>
            <label asp-for="GivenCommentary"></label><br />
            <textarea  asp-for="GivenCommentary"></textarea>
            <span asp-validation-for="GivenCommentary" ></span>
        </div>
        <div  style="padding-top:15px; padding-bottom:15px">
            <button type="submit" >Submit score</button>
        </div>

用戶應該給出評級并發表評論。我的問題是來自選中單選按鈕的值不會傳輸到模型。當我設定斷點并查看引數時，GivenServiceScore它總是0. 這似乎是一個小問題，但我不明白我錯過了什么。
這是模型：

public class UserScoreModel
    {
        [Required]
        [Display(Name = "Please give a rating")]
        public int GivenServiceScore { get; set; }
        [Required]
        [Display(Name = "Please leave a commentary")]
        public String GivenCommentary { get; set; }
    }

和控制器：

        [HttpPost]
        public async Task<IActionResult> UserReview(UserScoreModel score)
        {
            if(ModelState.IsValid)
            {
                UserReviews review = new UserReviews()
                {
                    GivenServiceScore = score.GivenServiceScore,
                    GivenCommentary = score.GivenCommentary,
                };

                _db.UserReviews.Add(review);
                _db.SaveChanges();

                ViewBag.CongratsMessage = "Thank you for participating!";
                return View();
            }
            return View();
        }

使用asp-for標簽后不需要添加id和name，會自動生成，如下所示：

看法：

@model WebApplication174.Models.UserScoreModel
    <form method="post" asp-action="GivenServiceScore">
        <div>
            <label asp-for="GivenServiceScore"></label><br />
            <input required asp-for="GivenServiceScore" type="radio" value="5" /> 5
            <input required asp-for="GivenServiceScore" type="radio" style="padding-left:15px" value="4" /> 4
            <input required asp-for="GivenServiceScore" type="radio" style="padding-left:15px" value="3" /> 3
            <input required asp-for="GivenServiceScore" type="radio" style="padding-left:15px" value="2" /> 2
            <input required asp-for="GivenServiceScore" type="radio" style="padding-left:15px" value="1" /> 1
            <span asp-validation-for="GivenServiceScore" ></span>
        </div>
        <h5 style="padding-top:15px; padding-bottom:15px">@ViewBag.CongratsMessage</h5>
        <div>
            <label asp-for="GivenCommentary"></label><br />
            <textarea  asp-for="GivenCommentary"></textarea>
            <span asp-validation-for="GivenCommentary" ></span>
        </div>
        <div  style="padding-top:15px; padding-bottom:15px">
            <button type="submit" >Submit score</button>
        </div>
    </form>

控制器：

 public IActionResult Index()
        {
            return View();
        }

        [HttpPost]
        public async Task<IActionResult> GivenServiceScore(UserScoreModel score)
        {
            if (ModelState.IsValid)
            {
                UserReviews review = new UserReviews()
                {
                    GivenServiceScore = score.GivenServiceScore,
                    GivenCommentary = score.GivenCommentary,
                };

                ViewBag.CongratsMessage = "Thank you for participating!";
                return View();
            }
            return View();
        }

結果：
