本文实例为大家分享了MVC+jQuery.Ajax异步实现增删改查和分页的具体代码，供大家参考，具体内容如下
1、Model层代码
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 MvcExamples;
using System.Web.Mvc;
namespace MvcExamples.Web.Models
{
public class StudentModels
{
/// <summary>
/// 获取学生信息列表
/// </summary>
public List<MvcExamples.Model.Student> StudentList { get; set; }
/// <summary>
/// 获取教工信息列表
/// </summary>
public List<MvcExamples.Model.Teacher> TeacherList { get; set; }
/// <summary>
/// 获取学生信息列表(分页)
/// </summary>
public PagedList<MvcExamples.Model.Student> GetStudentList { get; set; }
}
}
2、View层代码

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 ActionResult Index(int? pi, string sclass)

4、两个分页辅助类PagedList和MikePagerHtmlExtensions
PagedList辅助类

get;
set;
}
int PageIndex

get;
set;
}
int PageSize

get;
set;
}
bool IsPreviousPage

get;
}
}
public class PagedList<T> : List<T>, IPagedList
{

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;
}
/// <summary>
///
/// </summary>
public int PageIndex

set;
}
public bool IsPreviousPage

}
}
public bool IsNextPage
{
get
{
return ((PageIndex) * PageSize) < TotalCount;
}
}
}
public static class Pagination
{
public static PagedList<T> ToPagedList<T>(this IOrderedQueryable<T> source, int? index, int? pageSize)

return builder.ToString();

#endregion
}
}
