Set queue attributes example

var client = new AmazonSQSClient();

var attrs = new Dictionary<string, string>();

// Maximum message size of 128 KiB (1,024 bytes * 128 KiB = 131,072 bytes).
int maxMessage = 128 * 1024;

attrs.Add(QueueAttributeName.DelaySeconds,
  TimeSpan.FromSeconds(5).TotalSeconds.ToString());
attrs.Add(QueueAttributeName.MaximumMessageSize, maxMessage.ToString());
attrs.Add(QueueAttributeName.MessageRetentionPeriod,
  TimeSpan.FromDays(1).TotalSeconds.ToString());
attrs.Add(QueueAttributeName.ReceiveMessageWaitTimeSeconds,
  TimeSpan.FromSeconds(5).TotalSeconds.ToString());
attrs.Add(QueueAttributeName.VisibilityTimeout,
  TimeSpan.FromHours(1).TotalSeconds.ToString());
// Dead-letter queue attributes.
attrs.Add(QueueAttributeName.RedrivePolicy,
  "{\"maxReceiveCount\":" +
  "\"5\"," +
  "\"deadLetterTargetArn\":" +
  "\"arn:aws:sqs:us-east-1:80398EXAMPLE:MyTestDeadLetterQueue\"}");

var request = new SetQueueAttributesRequest
{
  Attributes = attrs,
  QueueUrl = "https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyTestQueue"
};

client.SetQueueAttributes(request);
