AWS SDKsコード例

次のコード例は、 Software AWS Development Kit (SDK) で Amazon Relational Database Service (Amazon RDS) を使用する方法を示しています。



クロスサービスの例は、複数の AWS のサービスで動作するサンプルアプリケーションです。



次のコード例は、Amazon RDS の使用を開始する方法を示しています。

using System; using System.Threading.Tasks; using Amazon.RDS; using Amazon.RDS.Model; namespace RDSActions; public static class HelloRds { static async Task Main(string[] args) { var rdsClient = new AmazonRDSClient(); Console.WriteLine($"Hello Amazon RDS! Following are some of your DB instances:"); Console.WriteLine(); // You can use await and any of the async methods to get a response. // Let's get the first twenty DB instances. var response = await rdsClient.DescribeDBInstancesAsync( new DescribeDBInstancesRequest() { MaxRecords = 20 // Must be between 20 and 100. }); foreach (var instance in response.DBInstances) { Console.WriteLine($"\tDB name: {instance.DBName}"); Console.WriteLine($"\tArn: {instance.DBInstanceArn}"); Console.WriteLine($"\tIdentifier: {instance.DBInstanceIdentifier}"); Console.WriteLine(); } } }
