Question

我有这样的模特。基本上我有一个类名字段和两个字段的开始和结束日期格式为MM / dd / yyyy

namespace WebApplication3.Models
{
    public class DateTimeViewModel
    {
        public DateTimeViewModel()
        {
            StartDate = new DateTime(DateTime.Today.Year, 1, 1);
            EndDate = new DateTime(StartDate.Year, 12, 31);
        }

        public int Id { get; set; }
        public string ClassName { get; set; }

        [Display(Name = "Start Date")]
        [Required(ErrorMessage = "{0} is required")]
        [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}", ApplyFormatInEditMode = true)]
        public DateTime StartDate { get; set; }

        [Display(Name = "End Date")]
        [Required(ErrorMessage = "{0} is required")]
        [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}", ApplyFormatInEditMode = true)]
        public DateTime EndDate { get; set; }
    }
}

这是我的观点

@model WebApplication3.Models.DateTimeViewModel

@{
    ViewBag.Title = "Create";
}

<h2>Create</h2>

@using (Html.BeginForm()) 
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>DateTimeViewModel</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div class="form-group">
            @Html.LabelFor(model => model.ClassName, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.ClassName, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.ClassName, "", new { @class = "text-danger" })
            </div>
        </div>
        <div class="form-group">
            @Html.LabelFor(model => model.StartDate, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.StartDate, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.StartDate, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.EndDate, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.EndDate, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.EndDate, "", new { @class = "text-danger" })
            </div>
        </div>
        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-default" />
            </div>
        </div>
    </div>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

这是我的HttpPost控制器

[HttpPost]
public ActionResult Create(WebApplication3.Models.DateTimeViewModel model)
{
    if(ModelState.IsValid)
    {
        /// do something
    }

    return View();
}

我现在遇到的问题是，当我输入如下图所示的日期时，我的ModelState.IsValid返回FALSE：

看起来每次我进入大于12的那天，我都会收到验证错误。

你知道为什么或我在这里做错了吗？

非常感谢你。

Answer 1

在您的网络配置文件中添加区域性：

 <system.web>

<globalization uiCulture="en" culture="en-GB"/>

并在全局asax中添加以下内容：

protected void Application_BeginRequest(object sender, EventArgs e)
    {
        CultureInfo culture = new CultureInfo("en-GB");
        Thread.CurrentThread.CurrentCulture = culture;
        Thread.CurrentThread.CurrentUICulture = culture;
    }

希望获得帮助。

将[DataType(DataType.Date)]添加到注释中。

为什么我的DateTime ModelState无效？
