如何针对“从查询到输出快捷方式”优化此方法

Question

我写了这种方法，但是我想对其进行优化。 我认为TResult output（Into中Pagination.cs方法中的参数）以及new HomeProjectViewModel()（ProjectService.cs中的参数）都可以删除，但我不能！ / p>

是否可以从方法中删除此参数？

Pagination.cs

 public static class Pagination
{

    public static async Task<TResult> Into<T, TSource, TResult>(this IQueryable<T> query, Func<List<T>, List<TSource>> source, TResult output, int page, int showLimit)
    {
        if (query == null) return output;

        var que = page > 1
            ? await query.Skip(showLimit * (page - 1)).Take(showLimit).Cacheable().ToListAsync().ConfigureAwait(false)
            : await query.Take(showLimit).Cacheable().ToListAsync().ConfigureAwait(false);

        var list = source.Invoke(que);

        var type = output.GetType();
        var pages = type.GetProperty("Pages");
        var currentPage = type.GetProperty("CurrentPage");
        var items = type.GetProperty("Items");

        if (pages == null || currentPage == null || items == null) return output;

        pages.SetValue(output, Numbers.RoundToUp((double)(await query.CountAsync().ConfigureAwait(false)) / showLimit));
        currentPage.SetValue(output, page);
        items.SetValue(output, list);

        return output;
    }

ProjectService.cs

public async Task<HomeProjectViewModel> HomeProjects(int page, int showLimit = 5)
    {
        var query = from project in _project
                    let pictures = from picture in project.Pictures where !picture.Deleted select picture.Filename
                    where !project.Deleted && !project.Hidden
                    orderby project.Added descending
                    select new
                    {
                        project.SmartId,
                        project.Text,
                        pictures,
                    };

        return await query.Into(que =>
            que.Select(project => new HomeProjectItemViewModel
            {
                SmartId = project.SmartId,
                Name = project.Text,
                Image = project.pictures.SelectRandom()
            }).ToList(), new HomeProjectViewModel(), page, showLimit);
    }

HomeProjectViewModel.cs

   public class HomeProjectViewModel
    {
        public List<HomeProjectItemViewModel> Items { get; set; }
        public int CurrentPage { get; set; }
        public int Pages { get; set; }
    }

此方法将是创建包含页面，当前页面等的类的快捷方式。

在我的项目中，许多方法看起来像HomeProjects()

我想创建方法而不是多行代码。
