Create, subscribe to, and publish topic example

var snsClient = new AmazonSimpleNotificationServiceClient();

var topicRequest = new CreateTopicRequest
{
  Name = "CodingTestResults"
};

var topicResponse = snsClient.CreateTopic(topicRequest);

var topicAttrRequest = new SetTopicAttributesRequest
{
  TopicArn = topicResponse.TopicArn,
  AttributeName = "DisplayName",
  AttributeValue = "Coding Test Results"
};

snsClient.SetTopicAttributes(topicAttrRequest);

snsClient.Subscribe(new SubscribeRequest
{
  Endpoint = "johndoe@example.com",
  Protocol = "email",
  TopicArn = topicResponse.TopicArn
});

// Wait for up to 2 minutes for the user to confirm the subscription.
DateTime latest = DateTime.Now + TimeSpan.FromMinutes(2);

while (DateTime.Now < latest)
{
  var subsRequest = new ListSubscriptionsByTopicRequest
  {
    TopicArn = topicResponse.TopicArn
  };

  var subs = snsClient.ListSubscriptionsByTopic(subsRequest).Subscriptions;

  var sub = subs[0];

  if (!string.Equals(sub.SubscriptionArn,
    "PendingConfirmation", StringComparison.Ordinal))
  {
    break;
  }

  // Wait 15 seconds before trying again.
  System.Threading.Thread.Sleep(TimeSpan.FromSeconds(15));
}

snsClient.Publish(new PublishRequest

  Subject = "Coding Test Results for " +
