![]() Void Application_Start(object sender, EventArgs e) If you are using an ASP.Net web application, you can take advantage of the Application_Start event of the Global.asax file and then make a call to JobScheduler.Start() method as shown in the code snippet below. You do not always need a windows service to start your scheduler. Here's a code snippet that illustrates how you can build a trigger like this. You can as well build a trigger that is fired every second and repeats it indefinitely. Once the trigger for the job is defined and configured using the needed cron expression, the trigger is registered with the job scheduler. Note how the name and group of the trigger has been specified when creating the trigger instance. ITrigger trigger = TriggerBuilder.Create() ![]() IJobDetail job = JobBuilder.Create().Build() IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler() The following code listing illustrates how we can define a trigger for our job and then register job and the trigger with the job scheduler. In essence, you can take advantage of job schedulers to schedule your jobs for execution. Now, how is that the jobs are scheduled? Well, there is a component called job scheduler that is responsible for scheduling your jobs. You can visit this link to generate cron expressions. The trigger will contain the job's metadata as cron expression. Now that you have already defined the job class, you'll need to create your own job scheduler class and define the trigger for your job. public void Execute(IJobExecutionContext context) Note that this implementation is not thread safe it's just for illustration purposes only. The code snippet given below writes the current DateTime value as a text to a file. Here's a simple implementation of the Execute method of the IDGJob class - I'll leave it to you to design your custom job class to suit your application's needs. Sample code that denotes the job to be performed Public void Execute(IJobExecutionContext context) The following code snippet illustrates how you can implement the IJob interface to design a custom job class using the Quartz.Net library. Incidentally, this interface declares the Execute method - you should implement this method in your custom job class. To create a job, you should create a class that implements the IJob interface. Note that you should register your jobs and triggers with the scheduler. The scheduler is the component that schedules the jobs. While a job denotes the task that needs to be executed, a trigger is used to specify how the job will be executed. The three primary components in Quartz are jobs, triggers and schedulers, i.e., to create and schedule jobs in Quartz.Net, you would need to have schedulers, triggers and jobs. ![]() You can also install Quartz.Net through the Package Manager Window in your Visual Studio IDE. You can install Quartz.Net from the downloads section of the Quartz official website.
