You can add a function to App_Code/ViewFunctions.cshtml (create if missing)

@using System.Web.Mvc;
@functions{
public static object ConditionalActionLink(object actionLink, ICollection arrAuthUsers)
{
    bool objIsVisible = arrAuthUsers
        .Select(s => User.IsInRole(s))
        .Where(s => s.Equals(true))
        .Any();

    return (objIsVisible)
        ? actionLink
        : MvcHtmlString.Empty;
}

To use that function just add following code to the view.

@ViewFunctions.ConditionalActionLink(
@Html.ActionLink("TextToDisplay", "SomeAction", new { Area = "SomeArea", Controller = "SomeController" }), 
new string[] { "administrator","jDoe", "someOtherUser" })
