Question

这是安排输出任务的主要步骤

Public Sub ScheduleOutput()

    Dim sf As ISchedulerFactory = New StdSchedulerFactory()

    Dim scheduler As IScheduler = sf.GetScheduler()
        scheduler.Start()

    Dim job As IJobDetail = JobBuilder.Create(Of OutputJob)().
                WithIdentity("output", "output").Build()

    Dim trigger As ITrigger = TriggerBuilder.Create().
                WithIdentity("trigger", "trigger").ForJob("output").
                WithSchedule(CronScheduleBuilder.DailyAtHourAndMinute(setHour.Text, setMinute.Text)).
                Build()
    MsgBox("end")

End Sub

和工作类别

Public Class OutputJob
    Implements IJob

    Public Sub Execute(context As IJobExecutionContext) Implements IJob.Execute

        Output()

    End Sub

    Public Sub Output()

        Dim b = Convert.FromBase64String(HttpContext.Current.Request.Form("encodedhtml"))
        Dim html = System.Text.Encoding.UTF8.GetString(b)

        HttpContext.Current.Response.Clear()
        HttpContext.Current.Response.ContentType = "text/html"
        HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=""Dashboard.html""")
        HttpContext.Current.Response.Write(html)
        HttpContext.Current.Response.End()

    End Sub

End Class

Web.config文件

<configuration>
  <configSections>
    <sectionGroup name="common">
      <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
    </sectionGroup>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
  </configSections>
  <common>
    <logging>
      <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net1213">
        <arg key="configType" value="INLINE"/>
        <arg key="configFile" value="~/log4net.config"/>
        <arg key="level" value="INFO" />
      </factoryAdapter>
    </logging>
  </common>
  <log4net>
    <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender">
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%d [%t] %-5p %l - %m%n" />
      </layout>
    </appender>
    <root>
      <level value="INFO" />
      <appender-ref ref="EventLogAppender" />
    </root>
  </log4net>
</configuration>

当我尝试运行代码时，Dim sf As ISchedulerFactory = New StdSchedulerFactory()发生了异常

something.dll中发生了'System.TypeInitializationException'类型的异常，但未在用户代码中处理

其他信息：“ Quartz.Impl.StdSchedulerFactory”的类型初始值设定项引发了异常。

输出中的异常消息（显示在Visual Studio的底部）：

类型的第一次机会异常 Common.Logging.dll中发生了'Common.Logging.ConfigurationException' 类型为“ System.TypeInitializationException”的第一次机会异常发生在something.dll

如何解决该异常？

以及代码中可能导致错误/异常的其他任何部分？

我为此一直苦苦挣扎，并寻找了很多解决方案，但是它们都无法真正帮助我（或者只是我不知道如何修改才能适合我的代码），因为我确实缺乏知识有关任务计划和配置设置。

Quartz仅依赖于一个称为Common.Logging的第三方库（该库包含允许您使用最适合您的日志记录提供程序的日志记录抽象）。您必须在应用程序二进制文件旁边具有Quartz.dll，Commong.Logging.dll和Commong.Logging.Core.dll，才能成功运行Quartz.NET

并将Common.Logging.Log4Net1213.dll部分替换为：

  <common>
    <logging>
      <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net1213">
        <arg key="configType" value="INLINE"/>
        <arg key="level" value="INFO" />
      </factoryAdapter>
    </logging>
  </common>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
            <assemblyIdentity name="Common.Logging" publicKeyToken="af08829b84f0328e" culture="neutral" />
            <bindingRedirect oldVersion="0.0.0.0-3.3.1.0" newVersion="3.3.1.0" />
        </dependentAssembly>
    </assemblyBinding>
  </runtime>

无法通过Quartz.NET安排任务
