Rendering html code using TagBuilder and ASP.NET MVC 4 (with Razor engine)

I would like to render `li` items using TagBuilder. My function ``` public static string RenderListTag(this HtmlHelper helper, string labelText, string action, string controller, bool isAdmin, string listCssClass = "") { string value = string.Empty; TagBuilder li = new TagBuilder("li"); TagBuilder anchor = new TagBuilder("a"); UrlHelper urlHelper = new UrlHelper(HttpContext.Current.Request.RequestContext); if (string.IsNullOrEmpty(action) || string.IsNullOrEmpty(controller)) { anchor.MergeAttribute("href", "#"); } else { anchor.MergeAttribute("href", urlHelper.Action(action, controller, new { area = isAdmin ? "Admin" : "" })); } anchor.SetInnerText(labelText); if (action.IsEqualWith(helper.ViewContext.RouteData.Values["action"].ToString())) { li.MergeAttribute("class", "active"); } if (!string.IsNullOrEmpty(listCssClass)) { li.MergeAttribute("class", listCssClass); } li.SetInnerText(anchor.ToString(TagRenderMode.Normal)); return li.ToString(TagRenderMode.Normal); } ``` When I call using the following code: ``` @Html.RenderListTag("Home", "Index", "Contents", false) @Html.RenderListTag("About", "About", "Home", false) @Html.RenderListTag("Contact", "Contact", "Home", false) @Html.RenderListTag("Show toolbar", "", "", false, "options no-display") @Html.RenderListTag("CMS", "Index", "Home", true) ``` The results is printed as text NOT html tag. ``` <li class="active">&lt;a href=&quot;/Contents&quot;&gt;Home&lt;/a&gt;</li> <li>&lt;a href=&quot;/Home/About&quot;&gt;About&lt;/a&gt;</li> <li>&lt;a href=&quot;/Home/Contact&quot;&gt;Contact&lt;/a&gt;</li> <li class="options no-display">&lt;a href=&quot;#&quot;&gt;Show toolbar&lt;/a&gt;</li> <li class="active">&lt;a href=&quot;/Admin/Home&quot;&gt;CMS&lt;/a&gt;</li> ``` I want to print the HTML tag not text. Where is my mistake ?
