c# - 为什么 Razor 不喜欢这个？

Question

我有一个非常烦人的问题，我认为:

@{

        if(ViewBag.Section == "Home")
        {
           <div id="headerfrontPage">   
        }
        else
        {
            <div id="header">   
        }


     }

我得到一个编译错误:

The code block is missing a closing "}" character. Make sure you have a matching "}" character for all the "{" characters within this block, and that none of the "}" characters are being interpreted as markup.

如何有条件地编写一个 div？它基本上是为了黑客...

Answer 1

当你包裹你的 div 的内部元素时，你可以使用相同的结构，比如:

@if (ViewBag.Section == "Home")
{
    <text><div id="headerfrontPage"></text>
}
else
{
    <text><div id="header"></text>
}

或者你使用razor语法@: like

@if (ViewBag.Section == "Home")
{
    @:<div id="headerfrontPage">
}
else
{
    @:<div id="header">
}

但对于您目前的情况，我更喜欢 Ron Sijm 的解决方案:

@{
var divName = ViewBag.Section == "Home" ? "headerfrontPage" : "header";
}

<div id="@divName">
