asp.net-mvc-3 – ASP.NET MVC – 扩展Ajax.ActionLink方法

编辑：这是我到目前为止：

public static class AjaxExtensions
    {
        public static IHtmlString MyActionLink(
        this AjaxHelper htmlHelper,string linkText,string action,string controller,object routeValues,AjaxOptions ajaxoptions,object htmlAttributes
    )
        {
            var urlHelper = new UrlHelper(htmlHelper.ViewContext.RequestContext);
            var anchor = new TagBuilder("a");
            anchor.InnerHtml = linkText;
            anchor.Attributes["href"] = urlHelper.Action(action,controller,routeValues);
            anchor.MergeAttributes(new RouteValueDictionary(htmlAttributes));
            return MvcHtmlString.Create(anchor.ToString());
        }
    }

但显然我需要添加默认Ajax.ActionLink包含的AjaxOptions内容,但我不确定它的定义是什么样的.

这样做的原因是我希望linkText是一个HtmlString,因为我想这样做：@ Ajax.MyActionLink(“< span class =”highlight“> Hello< / span> World”,.. .)

第二编辑：

我现在收到编译错误：

...does not contain a definition for 'MyActionLink' and the best extension method overload 'MyProject.Helpers.AjaxExtensions.MyActionLink(System.Web.Mvc.AjaxHelper,System.Web.HtmlString,string,object,System.Web.Mvc.Ajax.AjaxOptions)' has some invalid arguments

这是我的扩展方法：

public static IHtmlString MyActionLink(
        this AjaxHelper ajaxHelper,HtmlString linkText,AjaxOptions ajaxoptions
    )
        {
            return MyActionLink(ajaxHelper,linkText,action,routeValues,ajaxoptions);
        }

这是我如何使用它：

@Ajax.MyActionLink(@Html.Raw(item.ITEMID.Replace((string)ViewData["ID"],"<span class='highlighted'>" + (string)ViewData["ID"] + "</span>")),"MoreDetails",new { id = item.ITEMID },new AjaxOptions()
                       {
                           UpdateTargetId = "MoreDetails-" + item.ITEMID,InsertionMode = InsertionMode.Replace
                       })

第三编辑：

我改变了我的扩展方法：

public static IHtmlString MyActionLink(
            this AjaxHelper ajaxHelper,IHtmlString linkText,AjaxOptions ajaxoptions
        )
            {
                return MyActionLink(ajaxHelper,ajaxoptions);
            }

现在我收到以下错误：

Cannot evaluate expression because the current thread is in a stack overflow state. System.Collections.IDictionary
