There are more AWS SDK examples available in the AWS Doc SDK Examples GitHub repo.
Code examples for EventBridge Scheduler using AWS SDKs
The following code examples show you how to use Amazon EventBridge Scheduler with an AWS software development kit (SDK).
Basics are code examples that show you how to perform the essential operations within a service.
Actions are code excerpts from larger programs and must be run in context. While actions
show you how to call individual service functions, you can see actions in context in their related scenarios.
Scenarios are code examples that show you how to accomplish specific tasks by
calling multiple functions within a service or combined with other AWS services.
Get started
The following code examples show how to get started using EventBridge Scheduler.

- AWS SDK for .NET
-
public static class HelloScheduler
{
static async Task Main(string[] args)
{
// Use the AWS .NET Core Setup package to set up dependency injection for the EventBridge Scheduler service.
// Use your AWS profile name, or leave it blank to use the default profile.
using var host = Host.CreateDefaultBuilder(args)
.ConfigureServices((_, services) =>
services.AddAWSService<IAmazonScheduler>()
).Build();
// Now the client is available for injection.
var schedulerClient = host.Services.GetRequiredService<IAmazonScheduler>();
// You can use await and any of the async methods to get a response, or a paginator to list schedules or groups.
var results = new List<ScheduleSummary>();
var paginateSchedules = schedulerClient.Paginators.ListSchedules(
new ListSchedulesRequest());
Console.WriteLine(
$"Hello AWS Scheduler! Let's list schedules in your account.");
// Get the entire list using the paginator.
await foreach (var schedule in paginateSchedules.Schedules)
{
results.Add(schedule);
}
Console.WriteLine($"\tTotal of {results.Count} schedule(s) available.");
results.ForEach(s => Console.WriteLine($"\tSchedule: {s.Name}"));
}
