我在 Asp.Net Core 3.0 应用程序中使用 FoolProof COre。

我的模型是

    public class PaymentReceiveMVm
    {
     
        public int PayMode { get; set; }
        public string PaymentMode { get; set; }

        [Column(TypeName = "date")]
        [DataType(DataType.Date)]
        public Nullable<DateTime> DOCredit { get; set; } //= DateTime.Today.Date;

        [RequiredIf("PayMode",1,ErrorMessage ="Bank Name is Required")]
        public int? BID { get; set; }
        public string BankAccount { get; set; }

       }

我的 _Layout 页面包括：

    <script src="~/vendor/jquery/jquery.min.js"></script>
    <script src="~/vendor/bootstrap/js/bootstrap.min.js"></script>
    <script src="~/vendor/jquery-validation/jquery.validate.min.js"></script>
    <script src="~/lib/js/jquery.validate.min.js"></script>
    <script src="~/lib/js/jquery.validate.unobtrusive.min.js"></script>
    <script src="~/vendor/FoolProofValidation/mvcfoolproof.core.js"></script>
    <script src="~/vendor/FoolProofValidation/mvcfoolproof.jquery.validation.js"></script>
    <script src="~/vendor/FoolProofValidation/mvcfoolproof.unobtrusive.js"></script>

在我看来是

      $.validator.unobtrusive.parse("#EditPayReceiveM");

当输入正确时，数据工作正常。但是当RequiredIf验证失败时，Java Script中会出现系统异常，如下所示：

System.ArgumentNullException：值不能为空。（参数“项目”）在 Microsoft.AspNetCore.Mvc.Rendering.MultiSelectList..ctor（IEnumerable 项目，字符串 dataValueField，字符串 dataTextField，IEnumerable selectedValues，字符串 dataGroupField）

完整的 Razor 视图如下：

<script>
    $(document).ready(function () {
 $.validator.unobtrusive.parse("#EditPayReceiveM");

        //Adding Containers to temporary Data Table
        $('#BtnAdd').on('click', function () {
            if (!$("#EditPayReceiveM").valid()) {
                return false;
            }

         else {
                console.log('DOC', $('#TxtDOC').val());
                SaveModal(EditPayReceiveM, "/PaymentReceives/EditPayReceiveM", DtPaymentsReceived)
            }
            
        });

    });

</script>



<div class="modal-header">
