前台index.cshtml添加：
@using X.PagedList.Mvc.Core;
@using X.PagedList;
<form action="~/Comments/Index" method="post">
<p>
Title: <input type="text" name="search" />
<input type="submit" value="search" />
</p>
</form>
……
@Html.PagedListPager((IPagedList)ViewBag.OnePageOfProducts, page => Url.Action("Index", new { page }))
后台Index方法(注意不要写[HttpPost])：
public async Task<IActionResult> Index(int? page, string search)
{
var applicationDbContext = _context.Comments.OrderByDescending(x => x.PublishTime);
if (search != null)
{
var products = applicationDbContext.Where(x => x.Name.Contains(search)); //returns IQueryable<Product> representing an unknown number of products. a thousand maybe?
var pageNumber = page ?? 1; // if no page was specified in the querystring, default to the first page (1)
var onePageOfProducts = products.ToPagedList(pageNumber, 10); // will only contain 25 products max because of the pageSize
ViewBag.OnePageOfProducts = onePageOfProducts;
return View(await onePageOfProducts.ToListAsync());
}
else
{
var products = applicationDbContext; //returns IQueryable<Product> representing an unknown number of products. a thousand maybe?
var pageNumber = page ?? 1; // if no page was specified in the querystring, default to the first page (1)
var onePageOfProducts = products.ToPagedList(pageNumber, 10); // will only contain 25 products max because of the pageSize
ViewBag.OnePageOfProducts = onePageOfProducts;
return View(await onePageOfProducts.ToListAsync());
}
}
applicationDbContext是你取到的数据，你只需要改变x.Name的内容就可以实现根据x.xxxx的字段进行搜索，例如：x.Id、x.Content……
其它的代码除了数字10以外并不需要改动，默认是每页10条，你可以自己改成15条或20条。
