计算数据行并在视图ASP.net MVC中显示

Question

All i'm trying to do is count how many bookings have requested wheelchair access not sure with the best way....

using (var context = new TalyllynContext()) 
        {
            var count = context.Bookings.SqlQuery(" SELECT * FROM dbo.Booking Where Wheelchair_Access = 'true' ").Count();
        }
        ViewBag.Count = count;

This is what i want to happen in the SQL, but not sure how to make the view bag Count display the variable or is there a much better solution

In the view it can be anything as long as it shows the count value !!

Answer 1

If you are using razor do something like this.

<p>@ViewBag.Count</p>

That will display the value in the view if you use the code you showed.

Answer 2

您是否尝试过在using语句之前移动count变量，以便也可以在using之外访问它。

Answer 3

using (var context = new TalyllynContext()) 
    {
        ViewBag.Count = context.Bookings.SqlQuery(" SELECT * FROM dbo.Booking Where Wheelchair_Access = 'true' ").Count();
    }

return View()

Answer 4

是的，将视图移回工作了，谢谢您的救命，我也将其更改为示例

ViewBag.Count = db.Bookings.SqlQuery(" SELECT * FROM dbo.Booking Where Gift_Aid = 'true' ").Count();
