C# 使用IF/ELSE在Razor中显示和选项卡

我有一些标签：

    <div class="page-tabs">
    <ul class="nav nav-tabs">
        <li class='@(ViewBag.IsAmendment == "0" ? "active" : "")'>
            <a href='@Url.Action("ReviewDetails", "SongsManagement")' title="Original">Original</a>
        </li>
        @if (!Model.OriginalWork.IsNew)
    {
        <li class='@(ViewBag.IsAmendment == "1" ? "active" : "")'>
            <a href='@Url.Action("ReviewDetails", "SongsManagement",new {isAmendment=1} )' title="Amendment">Active Amendment</a>
        </li>
}
    </ul>
</div>

}

当前显示的是原始版本，如果数据库中的IsNew更改，则显示活动版本。有没有办法隐藏原始选项卡。如果有有效的修订，则将其与原件一起显示？

<div class="page-tabs">
    <ul class="nav nav-tabs">
    @if (!Model.OriginalWork.IsNew)
    {
        if(ViewBag.IsAmendment == "1")
        {
            <li>
                <a href='@Url.Action("ReviewDetails", "SongsManagement")' title="Original">Original</a>
            </li>
        }
        <li class='@(ViewBag.IsAmendment == "1" ? "active" : "")'>
            <a href='@Url.Action("ReviewDetails", "SongsManagement",new {isAmendment=1} )' title="Amendment">Active Amendment</a>
        </li>
    }
    </ul>
</div>


@如果（！Model.OriginalWork.IsNew）
{
如果（ViewBag.IsAmendment==“1”）
{


}
