Custom Helper in Asp.net mvc3

问题:

I have an ASP.NET MVC3 application. I would like to have a custom toolbar that I want to display in every form. This custom toolbar can have one or many action links.So, I need to develop a Custom Html helper that I can use like below;

@Html.CustomToolBar(items => {
          items.Add("Action","Controller","Name","Text");
          items.Add("Action1","Controller1","Name1","Text1");})

This custom extension will produce the links html and I will display it on my form. I have a ToolBarAction class and I would like to get List<ToolBarAction> from @Html.CustomToolBar.

  public class ToolbarAction
  {
    public string Name { get; set; }
    public string Action { get; set; }
    public string Controller { get; set; }
    public string Text { get; set; }

  }

Can you advise me how I can achieve this? If you could point me the appropriate resources, that would be great really..

Many thanks

Regards..

Something like this (I didn't know what the Name property was for, so I added it as the class):

public static class HelperExtensions
{
    public static MvcHtmlString Menu(this HtmlHelper html, Action<IList<ToolbarAction>> addActions)
    {
        var menuActions = new List<ToolbarAction>();
        addActions(menuActions);

        var htmlOutput = new StringBuilder();

        htmlOutput.AppendLine("<div id='menu'>");

        foreach (var action in menuActions)
            htmlOutput.AppendLine(html.ActionLink(action.Text, action.Action, action.Controller, new { @class = action.Name }).ToString());

        htmlOutput.AppendLine("</div>");

        return new MvcHtmlString(htmlOutput.ToString());
    }
}
