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

I would like to render

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", "#");
anchor.MergeAttribute("href", urlHelper.Action(action, controller, new
area = isAdmin ? "Admin" : ""


if (action.IsEqualWith(helper.ViewContext.RouteData.Values["action"].ToString()))
li.MergeAttribute("class", "active");

if (!string.IsNullOrEmpty(listCssClass))
li.MergeAttribute("class", listCssClass);


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 ?


Use @Html.Raw(Html.RenderListTag("CMS", "Index", "Home", true))
