Ejemplos de código para Amazon SQS con SDK AWS
Los siguientes ejemplos de código muestran cómo utilizar Amazon Simple Queue Service (Amazon SQS) con AWS un kit de desarrollo de software (SDK).
Las acciones son extractos de código de programas más grandes y deben ejecutarse en contexto. Mientras las acciones muestran cómo llamar a las funciones de servicio individuales, es posible ver las acciones en contexto en los escenarios relacionados y en los ejemplos entre servicios.
Los escenarios son ejemplos de código que muestran cómo llevar a cabo una tarea específica llamando a varias funciones dentro del mismo servicio.
Los ejemplos con varios servicios son aplicaciones de muestra que funcionan con varios Servicios de AWS.
Introducción
En los siguientes ejemplos de código se muestra cómo empezar a utilizar Amazon SQS.

Console.WriteLine($"Hello Amazon SQS! Following are some of your queues:");
Console.WriteLine();
// You can use await and any of the async methods to get a response.
// Let's get the first five queues.
var response = await sqsClient.ListQueuesAsync(
new ListQueuesRequest()

});
foreach (var queue in response.QueueUrls)
