我在过去创造了一个辅助函数来只有当条件满足这样返回的输出：

I have in the past created a helper function to only return output when a criteria is met like this:

public static MvcHtmlString If(this MvcHtmlString value, bool evaluation)
{
     return evaluation ? value : MvcHtmlString.Empty;
}

所以你可以使用这样的：

so you can use this:

@Html.ActionLink("Create New", "Create").If(User.IsInRole("Administrators"))

这事情是这样的清晰，短

This way it is legible and short
