Question

我是MVC5编程的初学者。我正在使用MVC5和Entity框架6。我有一个类和一个DateTime属性，如下所示：

 public ActionResult Create([Bind(Include = "MelliCode,EnCode,grade,quota,password,FName,Lname,shenasname,FatehrName,sex,tel,mobile,ResAddress,WorkAddress")] Expert expert)
    {
        if (ModelState.IsValid)
        {
            db.Experts.Add(expert);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        return View(expert);
    }

我的控制员：

<div class="form-group">
        @Html.LabelFor(model => model.BirthDay, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.EditorFor(model => model.BirthDay, new { htmlAttributes = new { @class = "form-control" } })
            @Html.ValidationMessageFor(model => model.BirthDay, "", new { @class = "text-danger" })
        </div>

我的观点是这样的：

//You can replace the timeline_type with a detailed descrition as given below.
var timelineType = {
    accepted: 'Accepted An Answer',
    answered: 'Posted An Answer',
    asked: 'Asked A Question',
    badge: 'Earned A Badge',
    commented: 'Posted A Comment',
    reviewed: 'Reviewed A Suggested Edit',
    revision: 'Edited A Post',
    suggested: 'Suggested An Edit'
};

var formattedFeeds = [];

$.get('https://api.stackexchange.com/2.2/users/6778969/timeline?site=stackoverflow&filter=!))x30_z', function (feeds) {
        feeds.items.forEach(function (feed) {
        var formattedFeed = {};
        formattedFeed.timeline_type = timelineType[feed.timeline_type];
        formattedFeed.title = feed.title || feed.detail;
        formattedFeed.detail = feed.detail || '';
        formattedFeed.creation_date = new Date(feed.creation_date * 1000);
        formattedFeeds.push(formattedFeed); 
    });
});

然而，在运行页面并输入数据库中的个人信息后，为生日插入null !!!为什么？

我发现了我的问题我在[Bind]属性

中忘记了生日

public ActionResult Create([Bind(Include = "BirthDay,MelliCode,EnCode,grade,quota,password,FName,Lname,shenasname,FatehrName,sex,tel,mobile,ResAddress,WorkAddress")] Expert expert)
    {
        if (ModelState.IsValid)
        {
            db.Experts.Add(expert);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

为什么总是在数据库中，DateTime属性为null？
