我刚刚在我的MVC网站上安装了Hangfire包.我创建了一个Startup类

[assembly: OwinStartup(typeof(Website.Startup))]

namespace Website
{
    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            Hangfire.ConfigureHangfire(app);
            Hangfire.InitializeJobs();
        }
    }
}

和一个Hangfire课程

public class Hangfire
{
    public static void ConfigureHangfire(IAppBuilder app)
    {
        app.UseHangfire(config =>
        {
            config.UseSqlServerStorage("DefaultConnection");
            config.UseServer();
            config.UseAuthorizationFilters(); 
        });
    }

    public static void InitializeJobs()
    {
        RecurringJob.AddOrUpdate<CurrencyRatesJob>(j => j.Execute(), "* * * * *");
    }
}

另外,我在一个单独的类库中创建了一个新工作

public class CurrencyRatesJob
{
    private readonly IBudgetsRepository budgetsRepository;

    public CurrencyRatesJob(IBudgetsRepository budgetsRepository)
    {
        this.budgetsRepository = budgetsRepository;
    }

    public void Execute()
    {
        try
        {
            var budgets …

我的网站上的 Automapper 有问题，我找不到解决方案。我创建了一个名为 AutoMapperProfile 的类，我想在其中放置我所有的地图

public class AutoMapperProfile: Profile
{
    private readonly IConfiguration _mapper;

    public AutoMapperProfile(IConfiguration mapper)
    {
        _mapper = mapper;
    }

    protected override void Configure()
    {
        base.Configure();

        _mapper.CreateMap<SlideDTO, Slide>();
        _mapper.CreateMap<Slide, SlideDTO>();
    }
}

出于 DI 目的，我使用 Ninject，因此我在 NinjectWebCommon 中添加了以下绑定：

kernel.Bind<IMappingEngine>().ToMethod(ctx => Mapper.Engine);
kernel.Bind<IConfigurationProvider>().ToMethod(x => Mapper.Engine.ConfigurationProvider);

控制器看起来像这样：

private readonly ISlideRepository slideRepository;
    private readonly IMappingEngine mappingEngine;

    public HomeController(
        ISlideRepository slideRepository,
        IMappingEngine mappingEngine)
    {
        this.slideRepository = slideRepository;
        this.mappingEngine = mappingEngine;
    }

    [HttpGet]
    public ActionResult Index()
    {
        var model = new IndexViewModel();
        var …

我创建了一个 ASP.NET MVC 网站。然后我创建了一个名为 Site.Scheduler 的类库，我想在其中放置我所有的触发器和作业。

我为测试目的创建了一个简单的工作

public class CurrencyRatesJob : IJob
{
    private readonly IBudgetsRepository budgetsRepository;

    public CurrencyRatesJob(IBudgetsRepository budgetsRepository)
    {
        this.budgetsRepository = budgetsRepository;
    }

    public void Execute(IJobExecutionContext context)
    {
        try
        {
            var budgets = new BudgetsDTO();
            var user = new UserDTO();

            budgets.Sum = 1;
            budgets.Name = "Quartz";
            user.Email = "email@g.com";

            budgetsRepository.InsertBudget(budgets, user);
        }
        catch (Exception ex)
        {
            throw new Quartz.JobExecutionException(ex);
        }
    }
}

和作业调度程序

public class CurrencyRatesJobScheduler
{
    public static void GetCurrencyRates()
    {
        try
        {
            IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler(); …

我的问题是:你如何检查给定的字符串是否是回文的字谜？

我在互联网上找到了Python的一些解决方案,但我不知道如何检查它.我正在考虑将strig转换为a char [],然后为每个角色获得HashCode,但是我被卡住了.
