Bootstrap 3在桌子上掉落圆角.在申请.table-bordered课程时,我应该申请哪些样式才能让他们回来,好吗？

UPDATE

到目前为止,我已经来到这个代码,没有任何效果.

从Bootstrap 2.3.2中获取的CSS:

.table-bordered
{
    -webkit-border-radius: 4px;
    -moz-border-radius: 4px;
    border-radius: 4px;
}

.table-bordered thead:first-child tr:first-child > th:first-child, .table-bordered tbody:first-child tr:first-child > td:first-child, .table-bordered tbody:first-child tr:first-child > th:first-child
{
    -webkit-border-top-left-radius: 4px;
    border-top-left-radius: 4px;
    -moz-border-radius-topleft: 4px;
}

.table-bordered thead:last-child tr:last-child > th:first-child, .table-bordered tbody:last-child tr:last-child > td:first-child, .table-bordered tbody:last-child tr:last-child > th:first-child, .table-bordered tfoot:last-child tr:last-child > td:first-child, .table-bordered tfoot:last-child tr:last-child > th:first-child
{
    -webkit-border-bottom-left-radius: 4px;
    border-bottom-left-radius: 4px;
    -moz-border-radius-bottomleft: 4px;
}

HTML代码:

<table class="table table-hover table-responsive table-bordered">
    <thead> …

我有一个静态类,我需要注入一些实例.静态类可以有一个静态构造函数,但它必须是无参数的.那么,我该怎么办呢？

我不想创建一个单身人士.我希望有一个静态类,其中一个方法对应该注入的实例进行操作.贝娄是我需要的一个例子.

public static class AuthenticationHelper
{
    // Fields.
    private static object _lock = new object();
    private static readonly UserBusiness _userBusiness; // <-- this field needs to be injected.

    // Public properties.
    public static User CurrentUser
    {
        get
        {
            if (IsAuthenticated)
            {
                User user = (User)Context.Session[SessionKeys.CURRENT_USER];

                if (user == null)
                {
                    lock (_lock)
                    {
                        if (user == null)
                        {
                            user = _userBusiness.Find(CurrentUserId);
                            Context.Session[SessionKeys.CURRENT_USER] = user;
                        }
                    }
                }

                return user;
            }

            return null;
        }
    }
    public static int CurrentUserId { …

我必须像下面那样运行一个查询.它实际上更复杂,但这是重要的部分:

var results =
    from b in _context.Bookings
    where b.ScheduleDate.Add(b.StartTime) >= DateTime.UtcNow
    select b;

但它给出了以下错误:

LINQ to Entities无法识别方法'System.DateTime.Add方法(System.TimeSpan)',并且此方法无法转换为商店表达式.

我该如何解决这个问题？

提前致谢.
