c# - ASP.NET MVC Razor 日期时间验证错误消息

问题描述

所以adjournHearingInfo的newHearingDate当我没有填写为错误信息时

值 '' 无效。" 值为 "1/1/0001 12:00:00 AM"

我无法弄清楚如何访问此检查以更改此错误消息。或者，如果这不可能，请删除此检查，以便我可以自己验证日期，然后生成我想要的错误消息。这可能吗？

目前，我可以向其中添加另一条错误消息，但我无法删除该错误消息。

DTO：

public class AdjournHearingDTO
{
    public int HearingID { get; set; }

    [Required(ErrorMessage ="Please enter a Date")]
    [Display(Name ="Additional Hearing Date")]
    [Range(typeof(DateTime), "1/1/1900","1/1/2060", ErrorMessage =("Please enter a valid date."))]
    public DateTime newHearingDate { get; set; }
}

.cshtml：

    public AdjournHearingDTO adjournHearingInfo { get; set; } 

    public IActionResult OnPost()
    {
        if (ModelState.IsValid)
        {
        }
        else
        {
            if (adjournHearingInfo.newHearingDate.Date.ToString() == "1/1/0001 12:00:00 AM")
            {
                ModelState.AddModelError("adjournHearingInfo.newHearingDate", "Invalid Date");
            };
            return Page();
        }
    }

HTML：

<form asp-page="AdjournHearing" method="post" name="AdjournHearingScreen" id="AdjournHearingForm">
    @if (!Model.ModelState.IsValid)
