Question

我在c＃

中有一个if条件

    if (item.ReporSubCategoryId == 1 || item.ReporSubCategoryId == 2 || 
        item.ReporSubCategoryId == 3 || item.ReporSubCategoryId == 4)
    {
<a  href="@Url.Action("GetPdf", "Report", new { report = item.ReporSubCategoryId })" >@item.ReportTitle</a>
    }

如果条件改变使用三元运算符，我想这样做吗？

使用show并隐藏这个标签（style='display:Myconditions?block:None'）

<a  href="@Url.Action("GetPdf", "Report", new { report = item.ReporSubCategoryId })" >@item.ReportTitle</a>

但是我试试这段代码

<a style='display:" @item.ReporSubCategoryId == 1 || @item.ReporSubCategoryId == 2 || @item.ReporSubCategoryId == 3 || @item.ReporSubCategoryId == 4 ?block:None"'href="@Url.Action("GetPdf", "Report", new { report = item.ReporSubCategoryId })" >@item.ReportTitle</a>

但它不起作用。你能为我的错误提供正确的解决方案吗？

试试这个..

@Html.ActionLink(item.ReportTitle, "GetPdf", "Report", new { report = item.ReporSubCategoryId }, 
 new { @style = "display:" 
  (item.ReporSubCategoryId == 1 || item.ReporSubCategoryId == 2 || item.ReporSubCategoryId == 3 || item.ReporSubCategoryId == 4)
   ? "block" : "none" }
})

根据您的情况添加“阻止”/“无”

(item.ReporSubCategoryId == 1 || item.ReporSubCategoryId == 2 || item.ReporSubCategoryId == 3 || item.ReporSubCategoryId == 4)
