How to create Html.ActionLink for Current URL? - asp.net-mvc

Question

Using ASP.NET MVC 5 and Bootstrap 3.2, I am trying to create an Html ActionLink for the current URL like in the Bootstrap example here:
https://www.quackit.com/bootstrap/bootstrap_3/tutorial/bootstrap_breadcrumbs.cfm
<ul class="breadcrumb">
<li>Home</li>
<li>Fruit</li>
<li class="active">Pears</li>
</ul>
Microsoft has a lot of information on their page for ActionLink
https://learn.microsoft.com/en-us/dotnet/api/system.web.mvc.html.linkextensions.actionlink?view=aspnet-mvc-5.2
There doesn't seem to be a version for creating the active list item unless I am missing something in those overloads.
So, how would I create an ActionLink for "Pears" in the unordered list above (no hyperlink and class="active")?

Answer 1

The solution was:
If you don't want a hyperlink, don't use the ActionLink
I still used an ActionLink for Home and for Fruit, but Pears just got the standard <li> treatment like below:
public static string BuildBreadcrumbNavigation(this HtmlHelper helper)
{
var result = string.Empty;
var controllerName = helper.ViewContext.RouteData.Values["controller"].ToString();
// optional condition: I didn't wanted it to show on home and account controller
if ((controllerName != "Home") && (controllerName != "Account"))
{
var homeLink = helper.ActionLink(
linkText: "Home",
actionName: "Index",
controllerName: "Home").ToHtmlString();
var sb = new StringBuilder($"<ol class='breadcrumb'><li>{homeLink}</li>");
var url = HttpContext.Current.Request.Url.ToString();
var urlParts = url.Split(new char[] { '/' });
if (!urlParts.Contains("Console"))
{
var controllerLink = helper.ActionLink(
linkText: controllerName.SplitTitleWords(),
actionName: "Index",
controllerName: controllerName);
sb.Append($"<li>{controllerLink}</li>");
} else
{
var a = $"Console";
sb.Append($"<li>{a}</li>");
}
var actionName = helper.ViewContext.RouteData.Values["action"].ToString();
sb.Append($"<li class=\"active\">{actionName.SplitTitleWords()}</li>");
result = sb.Append("</ol>").ToString();
}
return result;
}
SplitTitleWords is a custom extension that I wrote to break-up words such as AddPDFResource into Add PDF Resource.
public static string SplitTitleWords(this string value)
{
var cList = new List<char>();
if (!string.IsNullOrEmpty(value))
{
cList.Add(value[0]); // just add the first letter, whether caps, no caps, or number
for (var i = 1; i < value.Length; i++)
{
var c = value[i];
if (char.IsUpper(c))
{ // 01234567891234 0123456789012345
// check special cases like class AddPDFResource => Add PDF Resource
var c0 = value[i - 1];
if (char.IsUpper(c0))
{
if (i + 1 < value.Length)
{
var c1 = value[i + 1];
if (!char.IsUpper(c1))
{
cList.Add(' ');
}
}
} else
{
cList.Add(' ');
}
}
cList.Add(c);
}
}
var result = new String(cList.ToArray());
return result;
}
