Question

我已经阅读了几篇类似的帖子，但他们没有解决我的问题。这是可以正常工作的代码。

<ul>
    @foreach (var row in db.Query(readSchedule,dt,pd2))
        {      
            sid = @row.ScheduleId;
            pd = @row.Date.ToString();
            cn = @row.CourseName;
            cut = @row.Cutoff;
            cost = @row.Cost;
            fa = @row.Fadd;
            var dow=@row.Date.DayOfWeek;
            pp=@row.PrePay;
            <li><a href="/MyFiles/Signup1.cshtml?   &sid=@sid&pd=@pd&cn=@cn&cut=@cut&cost=@cost&fa=@fa&pp=@pp">
                   @cn on @pd (@dow)</a></li>
        }
</ul>

当我添加下面显示的if语句时，我收到语法错误消息;预期

<ul>

@foreach (var row in db.Query(readSchedule,dt,pd2))
    {      
        sid = @row.ScheduleId;
        pd = @row.Date.ToString();
        cn = @row.CourseName;
        cut = @row.Cutoff;
        cost = @row.Cost;
        fa = @row.Fadd;
        var dow=@row.Date.DayOfWeek;
        pp=@row.PrePay;
if (pp=="")
{pp="none";}
        <li><a href="/MyFiles/Signup1.cshtml?   &sid=@sid&pd=@pd&cn=@cn&cut=@cut&cost=@cost&fa=@fa&pp=@pp">
               @cn on @pd (@dow)</a></li>
    }

我不认为剃刀编译器是完美的，特别是当被要求在html和C＃之间来回切换时。话虽如此，我可能会以不需要切换的方式编写该行：

pp = @( (@row.PrePay == "" ? "none" : row.PrePay   )

webmatrix c＃if语句嵌入foreach casues语法错误
