如果您对RouteLink包装比有问题的简单的解决方案。
例如，我有一个包装方法RouteLinkEx：

If you have a wrapper over RouteLink than there is an easy solution of the problem. For example, I had a wrapper method RouteLinkEx:

public static string RouteLinkEx(this HtmlHelper helper,string text,string routeName,RouteValueDictionary rvd,object htmlAttributes)
      {

      UrlHelper uh = new UrlHelper(helper.ViewContext.RequestContext,helper.RouteCollection);
      // Add trailing slash to the url of the link
      string url = uh.RouteUrl(routeName,rvd) + "/";
      TagBuilder builder = new TagBuilder("a")
      {
        InnerHtml = !string.IsNullOrEmpty(text) ? HttpUtility.HtmlEncode(text) : string.Empty
      };
      builder.MergeAttributes(new RouteValueDictionary(htmlAttributes));
      builder.MergeAttribute("href",url);
      return builder.ToString(TagRenderMode.Normal);
      //---  
      }

当你看到我使用的参数首先生成URL。然后，我添加/在URL的结尾。然后我生成使用这些URL链接完成

As you see I used parameters to generate URL first. Then I added "/" at the end of the URL. and then I generated complete link using those URL.
