这个博客展示了如何在ASP.NET MVC中使用自定义的`MyPagedList`类实现分页功能。`MyPagedList`类继承了`IPagedList`接口，并提供了构造函数来根据当前页、每页大小和总项数进行初始化。在视图中，通过`@foreach`循环遍历分页数据，并使用`@Html.Pager`辅助方法创建分页链接。
View：
@model MyPagedList
@foreach (var itm in Model.PagedItems)
{
@itm}
@Html.Pager(Model,new PagerOptions{PageIndexParameterName = "id",PagerItemTemplate = "{0} "})
Model:
public class MyPagedList :IPagedList
{
public MyPagedList(IEnumerable currentPageItems,int pageIndex, int pageSize, int totalItemCount)
{
CurrentPageIndex = pageIndex;
PageSize = pageSize;
TotalItemCount = totalItemCount;
PagedItems = currentPageItems.ToList();
}
public MyPagedList(IEnumerable allItems, int pageIndex, int pageSize)
{
CurrentPageIndex = pageIndex;
PageSize = pageSize;
var items = allItems as IList ?? allItems.ToList();
TotalItemCount = items.Count();
int startIndex = (pageIndex - 1)*pageSize;
PagedItems = items.Skip(startIndex).Take(pageSize).ToList();
}
public List PagedItems { get; set; }
public int CurrentPageIndex { get; set; }
public int PageSize { get; set; }
public int TotalItemCount { get; set; }
public IEnumerator GetEnumerator()
{
return PagedItems.GetEnumerator();
}
IEnumerator IEnumerable.GetEnumerator()
{
return GetEnumerator();
}
}
Controller:
public ActionResult IPagedList(int id=1)
{
MyPagedList list=new MyPagedList(Enumerable.Range(1,88),id,5);
return View(list);
}
