首先,如果已经提出这个问题,我道歉,但我无法找到解决问题的方法。 我正在一个ASP.NET 4.0 Wepforms网站上工作,管理员将上传一张图片,它将被视为一个帖子,如图片博客。访问者可以使用fb评论对每张图片进行评论,并且可以喜欢它。目前iam使用每个帖子(图片)的查询字符串。但现在我想把每个网址作为一个热门搜索引擎优化。所以基本上我有两件事需要处理:

  1. 为管理员上传的每张图片制作唯一网址,网址应为其标题,例如“ www.example.com/posts/mexican-bulldog ”与blogengine或nopCommerce相同。目前iam在Global.asax中使用以下代码:

        void Application_Start(object sender, EventArgs e) 
        {
                RegisterRoutes(RouteTable.Routes);
    
        }
        public static void RegisterRoutes(RouteCollection routeCollection)
        {
            routeCollection.MapPageRoute("RouteForCustomer", "Customer/{Id}", "~/Customer.aspx");
    
    
    
            routeCollection.MapPageRoute("RouteForHome", "home", "~/Default.aspx");
            routeCollection.MapPageRoute("RouteForTroll", "post", "~/post.aspx"); 
    }    
    

    上面的代码没有解决我的问题,我必须静态分配网址。

  2. 想要在帖子之间导航,即下一个和之前的

  3. 提前完成!

请按照您的要求查看我刚刚实施的简单方法。可能有更多方法可以做到这一点。

我创建了一个类:Images

public class Images
    {      
        public string CurrentImage { get; set; }
        public string NextImage { get; set; }
        public string PreviousImage { get; set; }
        public string CurrentImagePhysicalName { get; set; }
        public Images(string currentImagePhysicalName, string Current, string Next, string Previous)
        {
            this.CurrentImagePhysicalName = currentImagePhysicalName;
            this.CurrentImage = Current;
            this.NextImage = Next;
            this.PreviousImage = Previous;
        }
    } 

注册路线并在应用程序启动时初始化图像集:

public class Global : HttpApplication
    {
        public static List<Images> col = new List<Images>();
        private void GetImages()
        {
            // Build this collection as per your requirement. This is just a sample. 
            // Logic is to store current, next, previous image details for current displaying image/page. 
            // Hope while storing image each will have unique name before saving and will have all details in db like path, display name, etc.

            col.Add(new Images("orderedList0.png", "orderedList0", "orderedList1", ""));
            col.Add(new Images("orderedList1.png", "orderedList1", "orderedList2", "orderedList0"));
            col.Add(new Images("orderedList2.png", "orderedList2", "orderedList3", "orderedList1"));
            col.Add(new Images("orderedList3.png", "orderedList3", "orderedList4", "orderedList2"));
            col.Add(new Images("orderedList4.png", "orderedList4", "", "orderedList3"));
        }

        void Application_Start(object sender, EventArgs e)
        {
            GetImages();            
            RegisterRoutes(RouteTable.Routes);
        }

        public static void RegisterRoutes(RouteCollection routeCollection)
        {
            routeCollection.MapPageRoute("RouteForImage", "Posts/{Name}", "~/Posts.aspx");

        } 
}

Posts.aspx

protected void Page_PreRender(object sender, EventArgs e)
        {
            string currentImage = RouteData.Values["Name"].ToString();
            if (!String.IsNullOrEmpty(currentImage))
            {
                Images image = Global.col.Find(x => x.CurrentImage == currentImage);
                // Get Current Image URL where actually it is stored using from image variable and render / set image path where you want to using image.CurrentImagePhysicalName 


                // Set Next - Previous Image urls
                if (!String.IsNullOrEmpty(image.NextImage))
                {
                    hyperlink_next.Visible = true;
                    hyperlink_next.Text = image.NextImage;
                    hyperlink_next.NavigateUrl = GetRouteUrl("RouteForImage", new { Name = image.NextImage });                    
                }
                else
                    hyperlink_next.Visible = false;

                if (!String.IsNullOrEmpty(image.PreviousImage))
                {
                    hyperlink_previous.Visible = true;
                    hyperlink_previous.Text = image.PreviousImage;
                    hyperlink_previous.NavigateUrl = GetRouteUrl("RouteForImage", new { Name = image.PreviousImage });
                }
                else
                    hyperlink_previous.Visible = false;
            }
        }

这只是一个示例演示。这里的主要想法是处理RouteData.Values["Name"].ToString()来处理动态网址。

希望这对你有用。
