EF中Link分页查询
// GET: Users
/// <summary>
/// 列表页
/// </summary>
/// <param name="pageIndex">起始页</param>
/// <param name="pageSize">一页大小</param>
/// <returns></returns>
public ActionResult Index(int pageIndex=1,int pageSize=5)
{
// ViewData.Model = dbContext.Users.AsEnumerable();
// int pagSize=int.Parse(Request["pageSize"]??"2");
// EF中使用Link分页查询语句
ViewData["pageIndex"] = pageIndex;
ViewData["pageSize"] = pageSize;
ViewData["total"] = dbContext.Users.Count(); //获取总行数
ViewData.Model = dbContext.Users
.OrderBy(u => u.Id) //根据id排序
.Skip(pageSize * (pageIndex - 1)) //跳过多少行
.Take(pageSize) //取多少行
.AsEnumerable(); //延迟加载，当真正使用（数据）时才执行sql语句。
return View();
