在JsonResult中实现分页

public class UserController : Controller
{
    private readonly IUserService _userService;

    public UserController(IUserService userService)
    {
        _userService = userService;
    }

    public JsonResult GetUsers(int page, int pageSize)
    {
        // 获取总记录数
        int totalRecords = _userService.GetTotalRecords();

        // 计算总页数
        int totalPages = (int)Math.Ceiling((double)totalRecords / pageSize);

        // 获取当前页的数据
        var users = _userService.GetUsers(page, pageSize);

        // 封装分页信息和数据
        var result = new
        {
            TotalRecords = totalRecords,
            TotalPages = totalPages,
            Users = users
        };

        return Json(result, JsonRequestBehavior.AllowGet);
    }
}
