3、Controller层代码

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using System.Web.Mvc.Ajax;namespace MvcExamples.Web.Controllers{ public class StudentController : Controller {  //  // GET: /Student/  MvcExamples.BLL.Student _Student = new MvcExamples.BLL.Student();  MvcExamples.BLL.Teacher _Teacher = new MvcExamples.BLL.Teacher();  ///   /// 演示  /// 
  ///   ///   ///   public ActionResult Index(int? pi, string sclass)  {   int PageIndex = pi ?? 1;   int PageSize = 5;   string sClass = sclass == null ? "95031" : sclass;   MvcExamples.Web.Models.StudentModels _StudentModels = new MvcExamples.Web.Models.StudentModels();   _StudentModels.StudentList = _Student.GetModelList("sclass=" + sClass);   _StudentModels.TeacherList = _Teacher.GetModelList("tsex='男'");   _StudentModels.GetStudentList = new PagedList(_Student.GetModelList("sclass=" + sClass).AsQueryable(), PageIndex, PageSize);   return View(_StudentModels);//返回一个Model  }  ///   /// 修改学生信息  /// 
  ///   ///   ///   ///   ///   ///   public ActionResult UpdateStudent(string no, string name, string sex, string birsthday, string sclass)  {   MvcExamples.Model.Student _student = new MvcExamples.Model.Student();   _student.sno = no;   _student.sname = name;   _student.ssex = sex;   _student.sbirthday = Convert.ToDateTime(birsthday);   _student.sclass = sclass;   _Student.Update(_student);      JsonResult json = new JsonResult();   json.Data = new   {    result = "true"   };   return json;  }  ///   /// 删除学生信息  /// 
  ///   ///   public ActionResult DeleteStudent(string no)  {   bool IsDelete= _Student.Delete(no);   JsonResult json = new JsonResult();   return json;   if (IsDelete)   {    json.Data = new    {     result = "true"    };   }   else   {    json.Data = new    {     result ="false"    };   }   return json;  }  ///   /// 添加学生信息  /// 
  ///   ///   ///   ///   ///   ///   public ActionResult AddStudent(string no, string name, string sex, string birsthday, string sclass)  {   MvcExamples.Model.Student _student = new MvcExamples.Model.Student();   _student.sno = no;   _student.sname = name;   _student.ssex = sex;   _student.sbirthday = Convert.ToDateTime(birsthday);   _student.sclass = sclass;   _Student.Add(_student);   JsonResult json = new JsonResult();   json.Data = new   {    result = "true"   };   return json;  }  ///   /// 提供弹出窗口的数据  /// 
  ///   ///   public ActionResult WindowData(int id)  {   JsonResult json = new JsonResult();   //这里给json数据(这里只是演示，下面数据是模拟的)   json.Data = new   {    name = "张三",    sex = "男"   };   return json;  } }}

4、两个分页辅助类PagedList和MikePagerHtmlExtensions

PagedList辅助类

using System;using System.Data;using System.Configuration;using System.Linq;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.HtmlControls;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Xml.Linq;using System.Collections.Generic;using System.Collections.Specialized;namespace System.Web.Mvc{ public interface IPagedList {  int TotalPage //总页数  {   get;  }  int TotalCount  {   get;   set;  }  int PageIndex  {   get;   set;  }  int PageSize  {   get;   set;  }  bool IsPreviousPage  {   get;  }  bool IsNextPage  {   get;  } } public class PagedList : List, IPagedList {  public PagedList(IQueryable source, int? index, int? pageSize)  {   if (index == null) { index = 1; }   if (pageSize == null) { pageSize = 10; }   this.TotalCount = source.Count();   this.PageSize = pageSize.Value;   this.PageIndex = index.Value;   this.AddRange(source.Skip((index.Value - 1) * pageSize.Value).Take(pageSize.Value));  }  public int TotalPage  {   get { return (int)System.Math.Ceiling((double)TotalCount / PageSize); }  }  public int TotalCount  {   get;   set;  }  /// /// /// 
  public int PageIndex  {   get;   set;  }  public int PageSize  {   get;   set;  }  public bool IsPreviousPage  {   get   {    return (PageIndex > 1);   }  }  public bool IsNextPage  {   get   {    return ((PageIndex) * PageSize) < TotalCount;   }  } } public static class Pagination {  public static PagedList ToPagedList(this IOrderedQueryable source, int? index, int? pageSize)  {   return new PagedList(source, index, pageSize);  }  public static PagedList ToPagedList(this IOrderedQueryable source, int? index)  {   return new PagedList(source, index, 10);  }  public static PagedList ToPagedList(this IQueryable source, int? index, int? pageSize)  {   return new PagedList(source, index, pageSize);  }  public static PagedList ToPagedList(this IQueryable source, int? index)  {   return new PagedList(source, index, 10);  } }}

MikePagerHtmlExtensions辅助类

using System;using System.Data;using System.Configuration;using System.Linq;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.HtmlControls;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Xml.Linq;using System.Web.Mvc;using System.Web.Routing;using System.Text;namespace System.Web.Mvc{ public static class MikePagerHtmlExtensions {    #region MikePager 分页控件  public static string MikePager(this HtmlHelper html, PagedList data)  {   string actioinName = html.ViewContext.RouteData.GetRequiredString("action");   return MikePager(html, data, actioinName);  }  public static string MikePager(this HtmlHelper html, PagedList data, object values)  {   string actioinName = html.ViewContext.RouteData.GetRequiredString("action");   return MikePager(html, data, actioinName, values);  }  public static string MikePager(this HtmlHelper html, PagedList data, string action)  {   return MikePager(html, data, action, null);  }  public static string MikePager(this HtmlHelper html, PagedList data, string action, object values)  {   string controllerName = html.ViewContext.RouteData.GetRequiredString("controller");   return MikePager(html, data, action, controllerName, values);  }  public static string MikePager(this HtmlHelper html, PagedList data, string action, string controller, object values)  {   return MikePager(html, data, action, controller, new RouteValueDictionary(values));  }  public static string MikePager(this HtmlHelper html, PagedList data, RouteValueDictionary values)  {   string actioinName = html.ViewContext.RouteData.GetRequiredString("action");   return MikePager(html, data, actioinName, values);  }  public static string MikePager(this HtmlHelper html, PagedList data, string action, RouteValueDictionary values)  {   string controllerName = html.ViewContext.RouteData.GetRequiredString("controller");   return MikePager(html, data, action, controllerName, values);  }  public static string MikePager(this HtmlHelper html, PagedList data, string action, string controller, RouteValueDictionary valuedic)  {   int start = (data.PageIndex - 5) >= 1 ? (data.PageIndex - 5) : 1;   int end = (data.TotalPage - start) > 9 ? start + 9 : data.TotalPage;   RouteValueDictionary vs = valuedic == null ? new RouteValueDictionary() : valuedic;   var builder = new StringBuilder();   builder.AppendFormat("");   if (data.IsPreviousPage)   {    vs["pi"] = 1;    builder.Append(Html.LinkExtensions.ActionLink(html, "首页", action, controller, vs, null));    builder.Append(" ");    vs["pi"] = data.PageIndex - 1;    builder.Append(Html.LinkExtensions.ActionLink(html, "上一页", action, controller, vs, null));    builder.Append(" ");   }   for (int i = start; i <= end; i++) //前后各显示5个数字页码   {    vs["pi"] = i;    if (i == data.PageIndex)    {     builder.Append("" + i.ToString() + " ");    }    else    {     builder.Append(" ");     builder.Append(Html.LinkExtensions.ActionLink(html, i.ToString(), action, controller, vs, null));    }   }   if (data.IsNextPage)   {    builder.Append(" ");    vs["pi"] = data.PageIndex + 1;    builder.Append(Html.LinkExtensions.ActionLink(html, "下一页", action, controller, vs, null));    builder.Append(" ");    vs["pi"] = data.TotalPage;    builder.Append(Html.LinkExtensions.ActionLink(html, "末页", action, controller, vs, null));   }   builder.Append(" 每页" + data.PageSize + "条/共" + data.TotalCount + "条 第" + data.PageIndex + "页/共" + data.TotalPage + "页 
");   return builder.ToString();  }  #endregion }}
