一种在aspnetboilerplate中进行分页和排序的简单方法

public class GetUsersInput : PagedResultRequestDto
{
    public string Sorting { get; set; }
}

public class UserAppService : ApplicationService
{
    private readonly IUserRepository _userRepository;

    public UserAppService(IUserRepository userRepository)
    {
        _userRepository = userRepository;
    }

    public async Task<PagedResultDto<UserDto>> GetUsers(GetUsersInput input)
    {
        var query = _userRepository.GetAll();

        // 应用排序规则
        if (!string.IsNullOrEmpty(input.Sorting))
        {
            query = query.OrderBy(input.Sorting);
        }

        // 获取总记录数
        var totalCount = await query.CountAsync();

        // 应用分页规则
        query = query.PageBy(input);

        // 获取分页数据
        var users = await query.ToListAsync();

        // 将结果映射为DTO对象
        var userDtos = ObjectMapper.Map<List<UserDto>>(users);

        // 创建并返回PagedResultDto对象
        return new PagedResultDto<UserDto>(totalCount, userDtos);
    }
}

public class UserController : ControllerBase
{
    private readonly UserAppService _userAppService;

    public UserController(UserAppService userAppService)
    {
        _userAppService = userAppService;
    }

    public async Task<IActionResult> GetUsers(GetUsersInput input)
    {
        var users = await _userAppService.GetUsers(input);
        return Ok(users);
    }
}
