原标题:BuildUrlFromExpression Adding Area to Url

我有一个拥有一个行政区的网站,我创建了一个超文本求助器,帮助我以我的看法制作不同规模的图像,其内容如下。

这是我的助手,

public static string Image<T>(this HtmlHelper helper, Expression<Action<T>> action,string alt) where T : Controller
    {
        string url = LinkExtensions.BuildUrlFromExpression(helper, action);
        return string.Format("<img src="{0}" alt="{1}" />", url, alt);
    }

我提出的问题是:string url = LinkExtensions.BuildUrlFromExpression(求助者,行动);正在将行政区添入卢尔。

        string actionMethodName = string.Empty;
        if (expression != null)
        {
            actionMethodName = expression.Method.Name;
        }
        string url = new UrlHelper(helper.ViewContext.RequestContext, helper.RouteCollection).Action(actionMethodName, typeof(T).Name.Remove(typeof(T).Name.IndexOf("Controller"))).ToString();         
        //string url = LinkBuilder.BuildUrlFromExpression<T>(helper.ViewContext.RequestContext, helper.RouteCollection, action);
        return string.Format("<img src="{0}" width="{1}" height="{2}" alt="{3}" />", url, width, height, alt);
    }
}
