c#斷點續傳MVC
這是Model層
using System; using System.Collections.Generic; using System.Linq; using System.Web;
namespace 續點上傳視訊圖片.Models { public class MovieModel { public string Id { get; set; } public string MovieName { get; set; } public string PhotoPath { get; set; } public string MoviePath { get; set; } } }
這是分頁類
using System; using System.Collections.Generic; using System.Linq; using System.Web;
namespace 續點上傳視訊圖片.Models { /// <summary> /// 分頁 /// </summary> public class Pager { public List<MovieModel> list { get; set; } public int count { get; set; } } }
這是控制器

這是新增頁面
需要拉指令碼
