pref@item.Id is content with razor, I need it code

I'm doing something like

@foreach (var item in Model)
<li id='pref@item.Id' >
..

the problem is that it's rendered as content '开发者_C百科pref@item.Id' the item.Id is not evaluated, anybody knows a way out of this ?

Razor thinks you're trying to render an email address. Try one of these two approaches:

<li id='pref@(item.Id)'>

<li id='<text>pref</text>@item.Id'>
