I know you could make a helper pretty easily given the data. So, if possible, please only submit answers that also include getting the data.

We are using an action filter for this.


 public override void OnActionExecuting(ActionExecutingContext filterContext)
  var controller = (Controller) filterContext.Controller;
  Breadcrumb[] breadcrumbs = _breadcrumbManager.PushBreadcrumb(_breadcrumbLinkText);

before you mention it, I too have a distaste for service location in the filter attributes - but we are left with few options. IBreadcrumbManager looks like this:

public interface IBreadcrumbManager
 Breadcrumb[] PushBreadcrumb(string linkText);

The implementation puts Breadcrumb objects into the Session. The Url is HttpContext.Current.Request.RawUrl

Is the implementation of IBreadcrumbManager somewhere we can look at? Where does _breakcrumbLinkText come from?
could you show a more detailed example of this solution to breadcrumb helper? Do you have any test solution you could share maybe? I don't really get it with the interface _breadcrumbManager/IBreadcrumbManager..

How would you go about displaying the breadcrumbs in a View?

@Chris: something like this:

     foreach (var item in ViewData.Get<Breadcrumb[]>())
    <a href="<%= Server.HtmlEncode(item.Url) %>"><%= item.LinkText %></a> &raquo;

Would you be so kind to show a bit more of your suggested implementation, it intrigues and confuses me all at the same time ;)

For example, where do you instantiate the _breadcrumbManager, and what does it do internally?

this should as well be a comment to some answer, shouldn't it?
