使用 Quartz.net 时无法加载类型 System.Configuration.ConfigurationManager

Question

我刚刚开始使用 Quartz.NET 调度程序。我只是从 https://www.quartz-scheduler.net/documentation/quartz-3.x/tutorial/using-quartz.html 复制代码来检查工作。

static async Task Main(string[] args)
{
    Console.WriteLine("Hello World!");
    // construct a scheduler factory using defaults
    StdSchedulerFactory factory = new StdSchedulerFactory();

    // get a scheduler
    IScheduler scheduler = await factory.GetScheduler();
    await scheduler.Start();

    // define the job and tie it to our HelloJob class
    IJobDetail job = JobBuilder.Create<HelloJob>()
                .WithIdentity("myJob", "group1")
                .Build();

    // Trigger the job to run now, and then every 40 seconds
    ITrigger trigger = TriggerBuilder.Create()
                .WithIdentity("myTrigger", "group1")
                .StartNow()
                .WithSimpleSchedule(x => x
                    .WithIntervalInSeconds(40)
                    .RepeatForever())
            .Build();

    await scheduler.ScheduleJob(job, trigger);
}

但即使在显式添加 System.Configuration.ConfigurationManager dll 后，我仍收到以下消息。

  System.Configuration.ConfigurationManager in the System.TypeLoadException
  HResult=0x80131522
  Message=Could not load type 'System.Configuration.ConfigurationManager' from assembly 'System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

  StackTrace:

   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
   at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult()
   at Scheduler.Program.<Main>d__0.MoveNext()

这是我的解决方案的目录结构。

请有人建议我如何解决这个问题。

您引用的 DLL system.configuration.configurationmanager.5.0.0.nupkg\lib\net461\ 是为 .NET 版本 4.6.1 构建的。

不幸的是，您的应用程序针对 .NET 版本 5 - 它基于 .NET Core 实现，如 official docs.

中所述

分辨率应该是：

引用 System.Configuration.ConfigurationManager 到 DLL 版本 .NET Core 或 .NET 5.
或将应用程序的基础更改为 .NET Framework 4.6.2 及更高版本（必须是 .NET FW）
