Abort Multipart Uploads

The TransferUtility class provides a method, AbortMultipartUploads, to abort multipart uploads in progress. An upload is considered to be in-progress once you initiate it and until you complete it or abort it. You provide a DateTime value and this API aborts all the multipart uploads, on that bucket, that were initiated before the specified DateTime and in progress.

Because you are billed for all storage associated with uploaded parts (see Multipart Upload and Pricing), it is important that you either complete the multipart upload to have the object created or abort the multipart upload to remove any uploaded parts.

The following tasks guide you through using the high-level .NET classes to abort multipart uploads.

High-Level API Multipart Uploads Aborting Process

1	Create an instance of the `TransferUtility` class by providing your AWS credentials.
2	Execute the `TransferUtility.AbortMultipartUploads` method by passing the bucket name and a `DateTime` value.

The following C# code sample demonstrates the preceding tasks.

TransferUtility utility = new TransferUtility(accessKeyID, secretAccessKey);
utility.AbortMultipartUploads(existingBucketName, DateTime.Now.AddDays(-7));

Example

The following C# code aborts all multipart uploads in progress that were initiated on a specific bucket over a week ago. For instructions on how to create and test a working sample, see Testing the .NET Code Examples

using System;
using System.Configuration;
using Amazon.S3; 
using Amazon.S3.Model; 
using System.Collections.Specialized;
using Amazon.S3.Transfer;

namespace s3.amazon.com.docsamples.highlevel_abortmultipartupload
{
    class Program
    {
        static string accessKeyID        = "";
        static string secretAccessKey    = "";

        static string existingBucketName = "***Provide bucket name***"; 

        static void Main(string[] args)
        {
            NameValueCollection appConfig = ConfigurationManager.AppSettings;
            accessKeyID        = appConfig["AWSAccessKey"];
            secretAccessKey    = appConfig["AWSSecretKey"];

            try
            {
                TransferUtility transferUtility = 
                    new TransferUtility(accessKeyID, secretAccessKey);
                // Aborting uploads that were initiated over a week ago.
                transferUtility.AbortMultipartUploads(
                    existingBucketName, DateTime.Now.AddDays(-7));
            }

            catch (AmazonS3Exception e)
            {
                Console.WriteLine(e.Message, e.InnerException);
            }
        }
    }
}

	Note
	You can also abort a specific multipart upload. For more information, see List Multipart Uploads.
