ASP.NET MVC Razor将不接受我的有效标记 [英] ASP.NET MVC Razor Won't Accept My Valid Markup

问题描述

我非常喜欢Razor语法，但是它肯定不够完美.例如，我有以下标记块.

I like the Razor syntax a lot, but it certainly falls short of perfect. For example, I have the following block of markup.

@if (Model.FeaturedDestinations != null && Model.FeaturedDestinations.Count() > 0)
{
    int column = 0;

    foreach (var d in Model.FeaturedDestinations)
    {
        column++;
        if (column > 4)
        {
            </div>
            @{ column = 1; }
        }
        if (column == 1)
        {
            @:<div class="row-fluid">
        }
        <div class="span3">
            @RenderDestination(d)
        </div>
    }
    </div>
}

因此，编辑器给了我弯曲的线条，指示我在开始的标签之前有一个结束的<div>标签.我可以忍受这一点.但是，当我运行该应用程序时，实际上收到了以下运行时错误:

So, the editor gives me the squiggly lines indicating that I have an ending <div> tag before an opening one. I can live with that. But when I run the app, I actually get the following run-time error:

遇到了结束标签"div"，但没有匹配的开始标签.您的开始/结束标签是否正确平衡?

Encountered end tag "div" with no matching start tag. Are your start/end tags properly balanced?

很明显，我不能忍受！那么，处理这个案件有什么窍门吗?我知道我在做什么，只要我想要的标记.但是Razor并不这么认为，它正在接管.

Obviously, I cannot live with that! So is there any trick for dealing with this case? I know what I'm doing as far as the markup I want. But Razor doesn't think so and it's taking over.

为什么MVC浪费循环检查平衡标签?

And why the heck is MVC wasting cycles checking for balanced tags?

推荐答案

出于我不了解的原因，以下内容解决了该问题:

For reasons I don't understand, the following corrected the issue:

@if (Model.FeaturedDestinations != null && Model.FeaturedDestinations.Count() > 0)
{
    int column = 0;

    foreach (var d in Model.FeaturedDestinations)
    {
        column++;

        if (column > 4)
        {
            @:</div>
            column = 1;
        }

        if (column == 1)
        {
            @:<div class="row-fluid">
        }
        <div class="span3">
            @RenderDestination(d)
        </div>
    }
    @:</div>
}

请注意在多个标签之前添加了@:.我不知道为什么这些是必要的-Razor突出显示它识别出这些是标签而不是代码.

Note the addition of @: before several tags. I don't know why these are necessary--the Razor highlighting indicated that it recognized these were tags and not code.

此外，为什么这会使错误消失?导致运行时错误的原因没有改变.也许有人可以为我填补空白.

Also, why did this make the error go away? The thing that caused the run-time error has not changed. Perhaps someone can fill in the blanks for me.
