You should add the Quartz service to the services contained in the Program.cs file. String message = 'This job will be executed again at: ' +

#Cron job example code#

Here’s the complete source code of your job class: using The above code when executed will insert a text message that contains the next execution time of the job. In this example, we’ve leveraged dotConnect for PostgreSQL, a high-performance object-relational mapper (ORM) for PostgreSQL, for connecting to and working with the PostgreSQL database. Using (PgSqlCommand cmd = new PgSqlCommand())Ĭmd.CommandText = 'INSERT INTO mo ' +Ĭmd.Parameters.AddWithValue('name', message)

New PgSqlConnection('User Id = postgres Password = sa123# ' + You can use the following code to write a text message into a PostgreSQL database table named Demo: string message = 'This job will be executed again at: ' + () The DemoJob class extends the IJob interface and implements the Execute method. Public Task Execute(IJobExecutionContext context) Now, create a new class named DemoJob in a file named DemoJob.cs with the following code in there: using Quartz Once you have written your code and configured the scheduler, your job will be executed as scheduled.

For example, you could configure it to run your job every minute, every hour, or every day. You can configure the scheduler to run your job at any interval you desire. This code will be executed when the Quartz.NET scheduler runs your job. This interface contains a single Execute method, which is where you should write your custom code. To write a Quartz.NET job, you must first create a class that implements the IJob interface. PM> Install-Package Creating a Quartz.Net Job

You can install them either from the NuGet Package Manager tool inside Visual Studio or, from the NuGet Package Manager console using the following command: PM> Install-Package Install NuGet Packagesīefore you get started building the framework, you should install dotConnect for PostgreSQL, Quartz, and packages in your project. Leave the Do not use top-level statements checkbox unchecked. Since we’ll not be using minimal APIs in this example, ensure that the Use controllers (uncheck to use minimal APIs) is checked.ġ1. Since we won’t use Open API in this example, deselect the Enable OpenAPI support checkbox.ġ0. Since we’ll not be using authentication in this example, select the Authentication type as None.ĩ. Disable the Configure for HTTPS and Enable Docker Support options (uncheck them).Ĩ. NET 6.0 (Long-term support) as the project version.ħ. In the Additional Information window, select. Optionally, checkmark the Place solution and project in the same directory checkbox.Ħ. Specify the project name and location to store that project in your system. Select ASP.NET Core Web API and click Next.

In this section, we’ll learn how to create a new ASP.NET 6 Core Web API project in Visual Studio 2022.ģ. Create a new ASP.NET 6 Core Web API Project

The scheduler is responsible for polling and running jobs according to predefined schedules. Triggers specify how a job should be executed, i.e., on what schedule. Jobs in Quartz.NET are represented by C# classes that implement the IJob interface. A job includes the code needed to carry out a task or job. Jobs, triggers, and schedulers are the three core ideas of Quartz.NET. Understanding Jobs, Triggers, and Schedules In the following sections, we’ll learn how to leverage Quartz.NET to schedule background jobs in ASP.NET 6 applications. Quartz.NET also has a rich set of features, such as support for firing jobs on a cron schedule or executing jobs in response to events. We’ll learn job, scheduler, and trigger in the next section. You can create a job class and then a scheduler and trigger and get started in a few lines of code. One of the great things about Quartz.NET is that it is easy to configure and use. You can use Quartz.NET to schedule multiple tasks, such as running background jobs, sending email notifications, or executing database maintenance tasks. NET applications, including ASP.NET 6 web applications. It has been used for a long time and offers good support for dealing with cron expressions. Quartz.NET is a free and open source.NET port of its Java Quartz Scheduling framework counterpart.

You can download PostgreSQL from here: What is Quartz.NET and why is it required? To deal with code examples, you’ll need the following tools: It shows how we can store messages in a PostgreSQL database using Devart for PostgreSql, Quartz.Net, and ASP.NET 6. This article covers cron jobs and how we can leverage Quartz.Net to schedule cron jobs in ASP.NET 6.
