Code examples for Amazon RDS using Amazon SDKs - Amazon Relational Database Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Code examples for Amazon RDS using Amazon SDKs

The following code examples show how to use Amazon RDS with an Amazon software development kit (SDK).

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios and cross-service examples.

Scenarios are code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

Cross-service examples are sample applications that work across multiple Amazon Web Services.

For a complete list of Amazon SDK developer guides and code examples, see Using this service with an Amazon SDK. This topic also includes information about getting started and details about previous SDK versions.

Get started

The following code examples show how to get started using Amazon RDS.

Amazon SDK for .NET

There's more on GitHub. Find the complete example and learn how to set up and run in the Amazon Code Examples Repository.

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(); } } }
