c# - 使用 Bootstrap Datepicker 选择 future 日期并将其传递给 ASP.NET MVC Controller

Question

我尝试将包含在 html 表单中的 Bootstrap 日期选择器的日期传递给 ASP.NET MVC3 Controller 。问题是当我选择过去的日期时，传递给 Controller ​​的模型有适当的 DateTime 字段填充了正确的值。但是，当我选择当前或 future 日期时，我在 StartDate DateTime 字段中得到 0001-01-01 值。这是 View 的代码:

@using (Ajax.BeginForm("AddNewActivity", "Home", null, new AjaxOptions
{
    HttpMethod = "Post",
    UpdateTargetId = "activitiesTableDiv",
    InsertionMode = InsertionMode.Replace,
    OnBegin = "disableButton"
}))
{
    @Html.ValidationSummary(true)
    <fieldset>
        <div class="editor-label">
            Start date
        </div>
        <div class="editor-field">
            <input id="StartDate" data-date-format="dd-mm-yyyy" class="pickDate form-control valid"
                type="text" name="StartDate" data-val-required="The StartDate field is required."
                data-val="true" />
            @Html.ValidationMessageFor(model => model.StartDate)</div>
    </fieldset>
}

Controller 端 - POST 方法:

public ActionResult AddNewActivity(ActivityModel model, FormCollection collection)
    {
        var test = model.StartDate;

         if (model.ObjectId == null)
            objectid = model.ObjectId;

        var jury = model.UserIds.Split(';').ExtractInt32();

        string[] emails = jury.Select(i => Storage.UserGetById(i).Email).ToArray();
        if (model.UserIds.Length > 1 && model.UserIds[model.UserIds.Length - 1] == ';')
            model.UserIds = model.UserIds.Substring(0, model.UserIds.Length - 1);

        var tags = HtmlHelperExtension.ExtractCheckListBoxResult(collection).Where(i => i.Item2).Select(i => i.Item1).ToArray();
        var groups = model.ChosenGroups.Where(i => i.Checked == true).Select(i => i.Id).ToArray();

        var url = String.Format("{0}://{1}{2}", Request.Url.Scheme, Request.Url.Authority, Url.Content("~/"));
        SendActivityEmails(model.Name, url + "OIP/Activity/", emails);

        return RedirectToAction("_Activities", "OIP");
    }

型号:

public class ActivityModel
{
    public long Id { get; set; }

    public string ObjectId { get; set; }

    public TagDTO[] Tags { get; set; }

    public ModelItemChecked[] ChosenTags { get; set; }

    public DateTime StartDate { get; set; }

    public DateTime Deadline { get; set; }

    public DateTime ResultsAnnouncement { get; set; }
}

我找不到有类似问题的人。

Answer 1

我认为问题出在以下代码中的日期格式字符串:

<input id="StartDate" data-date-format="dd-mm-yyyy" class="pickDate form-control valid"
            type="text" name="StartDate" data-val-required="The StartDate field is required."
            data-val="true" />

把data-date-format html属性去掉，你会发现又能用了。否则，如果您希望更改传递的日期格式，则需要在日期字段上添加以下属性:

[DisplayFormat(ApplyFormatInEditMode=true, DataFormatString="dd-mm-yyyy")]
public DateTime StartDate { get;set; }
