Simply you can do this in any view

    @Html.NavigationLink("Link1", "Index", "Home")
    @Html.NavigationLink("Link2", "Index", "Home")
    @Html.NavigationLink("Link3", "Index", "Home")
    @Html.NavigationLink("Links with Parameter", "myAction", "MyController", new{ id=999}, new { @class= " icon-next" })

After you add this method to a new class or existing HtmlExtensions class

public static class HtmlExtensions
{
    public static MvcHtmlString NavigationLink(this HtmlHelper html, string linkText, string action, string controller, object routeValues=null, object css=null)
    {
        TagBuilder aTag = new TagBuilder("a");
        TagBuilder liTag = new TagBuilder("li");
        var htmlAttributes = HtmlHelper.AnonymousObjectToHtmlAttributes(css);
        string url = (routeValues == null)?
            (new UrlHelper(html.ViewContext.RequestContext)).Action(action, controller)
            :(new UrlHelper(html.ViewContext.RequestContext)).Action(action, controller, routeValues);

        aTag.MergeAttribute("href", url);
        aTag.InnerHtml = linkText;
        aTag.MergeAttributes(htmlAttributes);

        if (action.ToLower() == html.ViewContext.RouteData.Values["action"].ToString().ToLower() && controller.ToLower() == html.ViewContext.RouteData.Values["controller"].ToString().ToLower())
            liTag.MergeAttribute("class","active");

        liTag.InnerHtml = aTag.ToString(TagRenderMode.Normal);
        return new MvcHtmlString(liTag.ToString(TagRenderMode.Normal));
    }
}
