QuartzHostedService 是一个用来在Asp.Net Core 中实现 Quartz 的任务注入依赖的nuget 包：

基本示例如下:

using System;using System.Collections.Generic;using System.Linq;using System.Threading.Tasks;using AspNetCoreSampleQuartzHostedService.Jobs;using Microsoft.AspNetCore.Builder;using Microsoft.AspNetCore.Hosting;using Microsoft.AspNetCore.Mvc;using Microsoft.Extensions.Configuration;using Microsoft.Extensions.DependencyInjection;using Microsoft.Extensions.Logging;using Microsoft.Extensions.Options;using Quartz;using QuartzHostedService;namespace AspNetCoreSampleQuartzHostedService{    public class Startup    {        public Startup(IConfiguration configuration)        {            Configuration = configuration;        }        public IConfiguration Configuration { get; }        // This method gets called by the runtime. Use this method to add services to the container.        public void ConfigureServices(IServiceCollection services)        {            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);            services.AddOptions();            services.Configure
     
      (Configuration);            services.Configure
      
       (options => { options.WriteText = "This is inject string"; });            services.AddQuartzHostedService()                    .AddQuartzJob
       
        ()                    .AddQuartzJob
        
         ()                    .AddQuartzJob
         
          ()                    .AddQuartzJob
          
           (); } // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IHostingEnvironment env, IOptions
           
             settings) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } app.UseMvc(); if (settings.Value.EnableHelloSingleJob) { app.UseQuartzJob
            
             (TriggerBuilder.Create().WithSimpleSchedule(x => x.WithIntervalInSeconds(1).RepeatForever())) .UseQuartzJob
             
              (() => { return TriggerBuilder.Create() .WithSimpleSchedule(x => x.WithIntervalInSeconds(1).RepeatForever()); }); } if (settings.Value.EnableHelloJob) { app.UseQuartzJob
              
               (new List
               
                 { TriggerBuilder.Create() .WithSimpleSchedule(x => x.WithIntervalInSeconds(1).RepeatForever()), TriggerBuilder.Create() .WithSimpleSchedule(x => x.WithIntervalInSeconds(2).RepeatForever()) }); app.UseQuartzJob
                
                 (() => { var result = new List
                 
                  (); result.Add(TriggerBuilder.Create() .WithSimpleSchedule(x => x.WithIntervalInSeconds(10).RepeatForever())); return result; }); } } }}

扩展方式示例:

public static class ModBusScheduler    {        public static void AddQuartzJobsService(this IServiceCollection services)        {            services.AddQuartzHostedService()                    .AddQuartzJob
     
      ("HAVC_Elev")                    .AddQuartzJob
      
       ("Lighting", "Lighting")                    .AddQuartzJobDetail(() => JobBuilder.Create
       
        ().WithIdentity("Meter").Build())                    .AddQuartzJobDetail(() => JobBuilder.Create
        
         ().WithIdentity("PowerDis").Build());        }        public static void UserQuartzJobsService(this IApplicationBuilder app, AppSettings settings)        {            app.UseQuartzJob
         
          ("HAVC_Elev", () =>             {                 return TriggerBuilder.Create()                           .WithIdentity("HAVC_Elev")                           .UsingJobData("modbus", settings.AC_ElevatorSlave)                           .UsingJobData("devicetype", "HAVC_Elev")                           .WithSimpleSchedule(x => x.WithIntervalInSeconds(5).RepeatForever()).StartNow();             });}
