VB.NET 中的 Razor 视图引擎怪癖 [英] Razor View Engine Quirks in VB.NET

问题描述

我刚刚下载了 MVC 3.0 RC，我很高兴开始使用它，尤其是 Razor 视图引擎.然而，由于这里有一些泥泞的人，我们被困在使用 VB.NET 而不是 C#.

I just downloaded the MVC 3.0 RC and I'm excited to start using it, especially the Razor view engine. However, due to a few stick in the mud type people here, we are stuck using VB.NET instead of C#.

当我开始尝试时，我注意到了一些怪癖.如果您使用 CSHTML 创建 Razor 视图，您可以编写如下代码:

When I started trying it out, I noticed some quirks. If you are creating a Razor view using CSHTML, you can write code like this:

@foreach(string genreName in Model.Genres)
{
    <li>@genreName</li>
}

Razor 将自动检测

文本是一个 HTML 标记，并将切换出代码模式".对于 VB.NET VBHTML 文件，这似乎不起作用.这让我把 @: 关键字放在每一行的前面，就像这样:

Razor will automatically detect that the <li> text is an HTML tag and will switch out of "code mode". With a VB.NET VBHTML file, this doesn't seem to be working. It's making me put the @: keyword in front of each line like this:

@For Each genreName As String In Model.Genres
    @:<li>@genreName</li>
Next

如果我没有它，我会收到运行时错误.此外，<text></text> 标签似乎不起作用.

If I don't have it there, I get a runtime error. Also, the <text></text> tags don't seem to work.

有人知道这里发生了什么或者是否有解决方法吗?

Anybody know what's going on here or whether there's a workaround?

推荐答案

我想说 Vb.net 需要它的原因是 vb 允许内联 xml 元素而 c# 不允许.

I would say the reason it's required in Vb.net is vb allows xml elements inline whereas c# does not.

Dim xmlMarkup = <someElement>Values</span>

因此，vb 的自然解析器的行为必须与 c# 不同，因此您必须使用 @ 告诉解析器转回 html.您可以使用 @ 和 @:.

Because of this the natural parser for vb must behave differently than c# so you have to tell the parser to escape back to html by using the @. You can use @ and @:.
