嵌套条件无法正确识别

Question

我正试图在使用Razor的if/else中嵌入foreach,但是我在Razor声称我错过了一个结束括号时遇到了一些问题.代码在下面,我注意到Visual Studio没有语法突出显示的"else",我猜这是问题所在:

    @if (ViewBag.user.administrativeRole != null)
    {
        <select name="administrativeRole" id="administrativeRole" class="selectInput" disabled="disabled">   
    }
    else // this else isn't syntax highlighted 
    {
        <select name="administrativeRole" id="administrativeRole" class="selectInput">
        @foreach (var role in ViewBag.roles)
        {
        if (ViewBag.user.administrativeRole != null && ViewBag.user.administrativeRole == role.superadmin)
        {
            <option value="@role.id" selected="selected">@role.name</option>
        }
        else
        {
            <option value="@role.id">@role.name</option>
        }
    }
}
</select>

这会产生以下错误:

if块缺少结束"}"字符.确保此块中的所有"{"字符都有匹配的"}"字符,并且没有任何"}"字符被解释为标记.

Line 58: @if (ViewBag.user.administrativeRole != null)
Line 59: {
Line 60:    <select name="administrativeRole" id="administrativeRole" class="selectInput" disabled="disabled">  

有什么想法吗？我猜我只是简单地说了一下语法,因为我是Razor的新手.

使用Html.DropDown处理Slaks,但如果您按照描述的方式使用代码,请尝试这样:

    @{
        if (ViewBag.user.administrativeRole != null)
        {
            @:<select name="administrativeRole" id="administrativeRole" class="selectInput" disabled="disabled">   
        }
        else  
        {
            @:<select name="administrativeRole" id="administrativeRole" class="selectInput">
            foreach (var role in ViewBag.roles)
            {
                 if (ViewBag.user.administrativeRole != null ViewBag.user.administrativeRole == role.superadmin)
                 {
                     @:<option value="@role.id" selected="selected">@role.name</option>
                 }
                 else
                 {
                    @:<option value="@role.id">@role.name</option>
                 }
            }
        }
     }
 </select>

这样做是做一个代码块然后逃出你真正想要打印到你的标记的东西.
