下列範例示範如何使用 適用於 .NET 的 AWS SDK，在儲存貯體上啟用 Transfer Acceleration。如需設定和執行程式碼範例的資訊，請參閱《適用於 .NET 的 AWS SDK開發人員指南》中的 適用於 .NET 的 AWS SDK 入門。

using Amazon;
using Amazon.S3;
using Amazon.S3.Model;
using System;
using System.Threading.Tasks;

namespace Amazon.DocSamples.S3
{
    class TransferAccelerationTest
    {
        private const string bucketName = "*** bucket name ***";
        // Specify your bucket region (an example region is shown).

            EnableAccelerationAsync().Wait();
        }

        static async Task EnableAccelerationAsync()
        {
                try
                {
                    var putRequest = new PutBucketAccelerateConfigurationRequest
                    {
                        BucketName = bucketName,

                        }
                    };
                    await s3Client.PutBucketAccelerateConfigurationAsync(putRequest);

                    var getRequest = new GetBucketAccelerateConfigurationRequest
                    {
                        BucketName = bucketName
                    };
                    var response = await s3Client.GetBucketAccelerateConfigurationAsync(getRequest);

                    Console.WriteLine("Acceleration state = '{0}' ", response.Status);
                }
                catch (AmazonS3Exception amazonS3Exception)
                {
                    Console.WriteLine(
                        "Error occurred. Message:'{0}' when setting transfer acceleration",
                        amazonS3Exception.Message);
                }
        }
    }
}

將物件上傳至已啟用 Transfer Acceleration 的儲存貯體時，您可以在建立用戶端時指定使用加速端點：

var client = new AmazonS3Client(new AmazonS3Config
            {
                RegionEndpoint = TestRegionEndpoint,
                UseAccelerateEndpoint = true
            }

如需使用 適用於 JavaScript 的 AWS SDK 啟用 Transfer Acceleration 的範例，請參閱《適用於 JavaScript 的 AWS SDK API 參考》中的 PutBucketAccelerateConfiguration 命令。

如需透過使用適用於 Python 的 SDK 來啟用 Transfer Acceleration 的範例，請參閱《AWS SDK for Python (Boto3) API 參考》中的 put_bucket_accelerate_configuration。
