昨天，我的人生朝一个方向前进；而今天却朝着另一个方向。昨天，我相信我不可能做的事；今天，我却做了。

项目结构:

这里写图片描述

实体类:

    public class Product
    {
        public string Name { get; set; }
        public string Category { get; set; }
    }

 public class SearchModel
    {
        public SearchModel()
        {
            page = 1;
        }

        public int? page { get; set; }
    }

 public class ViewByCategoriesViewModel
    {
        public IPagedList<Product> Products { get; set; }
        public string[] AvailableCategories { get; set; }
        public string[] Categories { get; set; }
    }

   public class ViewSourceViewModel
    {
        public string RazorCode { get; set; }
        public string ControllerCode { get; set; }
    }
