问题
I am working on making a scheduler, just like Windows Scheduler using Quartz.Net.
In Windows Scheduler, there is an option to stop a task from running if it takes more than the specified time. I have to implement the same in my scheduler.
But I am not able to find any extension method/setting to configure Trigger or Job accordingly.
I request some inputs or suggestions for it.

You can write small code to set a custom timout running on another thread. Implement IInterruptableJob interface and make a call to its Interrupt() method from that thread when the job should be interrupted. You can modify the following sample code as per your need. Please make necessary checks/config inputs wherever required.
public class MyCustomJob : IInterruptableJob
{
private Thread runner;
public void Execute(IJobExecutionContext context)
{
int timeOutInMinutes = 20; //Read this from some config or db.
TimeSpan timeout = TimeSpan.FromMinutes(timeOutInMinutes);
//Run your job here.
//As your job needs to be interrupted, let us create a new task for that.
var task = new Task(() =>
{
Thread.Sleep(timeout);
Interrupt();
});
task.Start();
runner = new Thread(PerformScheduledWork);
runner.Start();
}
private void PerformScheduledWork()
{
//Do what you wish to do in the schedled task.
}
public void Interrupt()
{
try
{
runner.Abort();
}
catch (Exception)
{
//log it!
}
finally
{
//do what you wish to do as a clean up task.
}
}
}
