• MVC分页之MVCPager


    一、MVCPager异步

    model

        public class Article
        {
            [Display(Name = "信息编号")]
            public int ID { get; set; } 
    
            [Display(Name = "信息标题")]
            public string Title { get; set; }
    
            [Display(Name = "信息内容")]
            public string Content { get; set; }
        }
    
    public class AjaxPager
        {
            public PagedList<Article> Articles { get; set; } 
        }
    Model Code

    control

                //数据组装到viewModel
                Models.MyTest.MVCPager model = new Models.MyTest.MVCPager();
