在ASP.NET Core 2.0中工作的控制器:

[Produces("application/json")]
[Route("api/[controller]")]
[ApiController]
public class GraficResourcesApiController : ControllerBase
{    
    private readonly ApplicationDbContext _context;

    public GraficResourcesApiController(ApplicationDbContext context)
    {
        _context = context;
    }

    [HttpGet]
    public JsonResult GetGrafic(int ResourceId)
    {
        var sheduling = new List<Sheduling>();


        var events = from e in _context.Grafic.Where(c=>c.ResourceId == ResourceId)
                     select new
                     {
                         id = e.Id,
                         title = e.Personals.Name,
                         start = e.DateStart,
                         end = e.DateStop,
                         color = e.Personals.Color,
                         personalId = e.PersonalId,
                         description = e.ClientName
                     };
        var rows = events.ToArray();

        return Json(rows);
    }
}

在ASP.NET Core 2.1中 …

有三种型号:

承包商:

public class Contractor
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public ICollection<ReportWork> ReportWorks { get; set; }
    }

报告:

public class Report
    {
        public int Id { get; set; }       
        public string Name { get; set; }        
        public ICollection<ReportWork> ReportWorks { get; set; }
    }

报告工作:

public class ReportWork
    {
        public int Id { get; set; }
        public string ReportStatus { get; set; }        
        public int ReportId { get; set; …

如何在后台的计时器上写入数据库。例如，检查邮件并将新字母添加到数据库。在示例中，我在写入数据库之前简化了代码。

Microsoft示例中的类名称。录音课本身：

namespace EmailNews.Services
{

internal interface IScopedProcessingService
{
    void DoWork();
}

internal class ScopedProcessingService : IScopedProcessingService
{
    private readonly ApplicationDbContext _context;
    public ScopedProcessingService(ApplicationDbContext context)
    {
        _context = context;
    }

    public void DoWork()
    {
        Mail mail = new Mail();
        mail.Date = DateTime.Now;
        mail.Note = "lala";
        mail.Tema = "lala";
        mail.Email = "lala";
        _context.Add(mail);
        _context.SaveChangesAsync();
    }
}
}

计时器类：

namespace EmailNews.Services
{
#region snippet1
internal class TimedHostedService : IHostedService, IDisposable
{
    private readonly ILogger _logger;
    private Timer _timer;

    public TimedHostedService(IServiceProvider services, ILogger<TimedHostedService> …
