<p>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.</p>

We are using an action filter for this.
...
```
```
public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var controller = (Controller) filterContext.Controller;
        Breadcrumb[] breadcrumbs = _breadcrumbManager.PushBreadcrumb(_breadcrumbLinkText);
        controller.ViewData.Add(breadcrumbs);
    }
```
```
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
```
