问题:

I'm trying to output some Twitter handles in ASP.NET MVC3 in conjunction with the Twitter @Anywhere API, and I haven't been able to figure out how to actually escape the "@" symbol in a Razor view.

Does anyone know what the syntax is for escaping the "@" character in Razor?

I've tried using <text></text> and that results in a JIT error.

回答1:

You have to use @@ to escape the @ symbol.

One important thing to notice is that you DO NOT need to escape the @ symbol when it exists within an email address. Razor should be smart enough to figure that out on its own.

回答2:

If you are adding Twitter meta tags

and your Twitter username is, say, blrbr ( follow me ;) )

it should look like this

<meta name="twitter:site" content=@("@blrbr")>

回答3:

if you need to comment @ symbols in css code and just @@ wont work, use this:

@("@@font-face"){ ... css ...}

I had yet another odd case: pass '@' + @Model.SomeProperty to a link href.

The best solution for this case was given IMO in this answer to a similar question. Both @@ and @: didn't work while using the html code @ would complicate things.

So, my code was <a href="~/path/?query=@('@')@Model.SomePropery">

@Html.Raw('@')@Model.SomePropery would have worked as well.
