Render in MVC a link with image and text

Hi guys, I want in MVC to render a text with an image as an ActionLink. For creating a simple anchor tag, we use Html.ActionLink() helper which generates anchor tag for us.

If you want to create something a bit more complicated, you must create you own component. For this reason, I created the following code. It allows you to create an anchor with an image and a text.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;

namespace PSC.MVC.Helpers
{
    public static class CustomHtmlHelpers
    {
        /// 

        /// Enum ImageAndText
        /// 
        public enum ImageAndText
        {
            /// 

            /// Image on the left, text on the right
            /// 
            ImageOnTheLeft,

            /// 

            /// Text on the left, image on the right
            /// 
            ImageOnTheRight
        }

        /// 

        /// Images the action link.
        /// 
        /// The HTML helper.
        /// The link text.
        /// The action.
        /// The controller.
        /// The route values.
        /// The HTML attributes.
        /// The image source.
        /// The alternate text.
        /// The text style.
        /// The image style.
        /// The image position.
        /// IHtmlString.
        public static IHtmlString ImageActionLink(
               this HtmlHelper htmlHelper, string linkText, string action, 
               string controller, object routeValues, object htmlAttributes, 
               string imageSrc, string alternateText = "", 
               string textStyle = "", string imageStyle = "", 
               ImageAndText imagePosition = ImageAndText.ImageOnTheLeft)
        {
            var urlHelper = new UrlHelper(
                    htmlHelper.ViewContext.RequestContext);

            // create the image
            var img = new TagBuilder("img");
            img.Attributes.Add("src", 
                    VirtualPathUtility.ToAbsolute(imageSrc));
            if (!string.IsNullOrEmpty(alternateText))
                img.Attributes.Add("alt", alternateText.Trim());
            if (!string.IsNullOrEmpty(imageStyle))
                img.Attributes.Add("style", imageStyle);

            // create a render for the image and the text
            string render = "";
            if (imagePosition == ImageAndText.ImageOnTheLeft)
                render = img.ToString(TagRenderMode.SelfClosing) + linkText;
            else
                render = linkText + img.ToString(TagRenderMode.SelfClosing);

            // create the anchor with image and text
            var anchor = new TagBuilder("a") {
                InnerHtml = render
            };
            if (!string.IsNullOrEmpty(textStyle))
                anchor.AddCssClass(textStyle);

            // add reference to the anchor
            anchor.Attributes["href"] = urlHelper.Action(action, 
                                                         controller, 
                                                         routeValues);
            anchor.MergeAttributes(new RouteValueDictionary(htmlAttributes));

            return MvcHtmlString.Create(anchor.ToString());
        }
    }
}

In your MVC code you have to add:

@using PSC.MVC.Helpers;

and then you can call your component:

@Html.ImageActionLink("Your text", "Index", "Home", null, null, 
                      "~/Content/images/img.png", "Logo", "navbar-brand", 
                      "width: 40px;")
