using System; using System.Threading.Tasks; using Amazon.SimpleNotificationService; using Amazon.SimpleNotificationService.Model; /// <summary> /// This example shows how to use Amazon Simple Notification Service /// (Amazon SNS) to add a new Amazon SNS topic. /// </summary> public class CreateSNSTopic { public static async Task Main() { string topicName = "ExampleSNSTopic"; IAmazonSimpleNotificationService client = new AmazonSimpleNotificationServiceClient(); var topicArn = await CreateSNSTopicAsync(client, topicName); Console.WriteLine($"New topic ARN: {topicArn}"); } /// <summary> /// Creates a new SNS topic using the supplied topic name. /// </summary> /// <param name="client">The initialized SNS client object used to /// create the new topic.</param> /// <param name="topicName">A string representing the topic name.</param> /// <returns>The Amazon Resource Name (ARN) of the created topic.</returns> public static async Task<string> CreateSNSTopicAsync(IAmazonSimpleNotificationService client, string topicName) { var request = new CreateTopicRequest { Name = topicName, }; var response = await client.CreateTopicAsync(request); return response.TopicArn; } }
创建一个具有名称、特定属FIFO性和重复数据消除属性的新主题。
