How to use and display PagedResultDto

问题

Using ASPNet Boilerplate, and returning a pagedResultSetDto with the below code, how do I display the page links?

 public PagedResultDto<ArticleDto> GetAll()
    {
        var articleCount = articleRepository.Count();

        var t = articleRepository.GetAllIncluding(x => x.articleImage).Include(x => x.Category).Where(
                x => x.PublishFrom <= DateTime.Now &&
                x.PublishTo >= DateTime.Now &&
                 x.Status == PostStatus.Published &&
                 x.IsDeleted == false
                ).OrderByDescending(x=> x.PublishFrom).ToList();

        return new PagedResultDto<ArticleDto>
        {
            TotalCount = articleCount,
            Items = t.MapTo<List<ArticleDto>>()
        };
    }

First, take in IPagedResultRequest as input:

// using Abp.Linq.Extensions;

public PagedResultDto<ArticleDto> GetAll(PagedResultRequestDto input)
{
    var articleCount = articleRepository.Count();

    var t = articleRepository
            .GetAllIncluding(x => x.articleImage)
            .Include(x => x.Category)
            .Where(x =>
                x.PublishFrom <= DateTime.Now &&
                x.PublishTo >= DateTime.Now &&
                x.Status == PostStatus.Published &&
                x.IsDeleted == false
            )
            .OrderByDescending(x => x.PublishFrom)
            .PageBy(input) // Page by SkipCount and MaxResultCount
            .ToList();

    return new PagedResultDto<ArticleDto>
    {
        TotalCount = articleCount,
        Items = t.MapTo<List<ArticleDto>>()
    };
}

Then create your own links to pass in SkipCount, e.g. GetAll?SkipCount=10 for page 2.

MaxResultCount has a default value of 10.

You can calculate it according to the result of GetAll(). You request how many records you want. Let's say 10 (default value). It returns TotalCount and Items (=records). Let's say TotalCount = 95. Divide 95/10 = 9.5 ~=> 10 pages. Show 10 links. While 9 pages will show 10 records, last page will have 5 records. That
