Abort Multipart Uploads to an S3 Bucket Using the AWS SDK for .NET (Low-Level)

You can abort an in-progress multipart upload by calling the AmazonS3Client.AbortMultipartUploadAsync method. In addition to aborting the upload, this method deletes all parts that were uploaded to Amazon S3.

To abort a multipart upload, you provide the upload ID, and the bucket and key names that are used in the upload. After you have aborted a multipart upload, you can't use the upload ID to upload additional parts. For more information about Amazon S3 multipart uploads, see Multipart Upload Overview.

The following C# example shows how to abort an multipart upload. For a complete C# sample that includes the following code, see Upload a File to an S3 Bucket Using the AWS SDK for .NET (Low-Level API).

AbortMultipartUploadRequest abortMPURequest = new AbortMultipartUploadRequest

{

BucketName = existingBucketName,

Key = keyName,

UploadId = initResponse.UploadId

};

await AmazonS3Client.AbortMultipartUploadAsync(abortMPURequest);

You can also abort all in-progress multipart uploads that were initiated prior to a specific time. This clean-up operation is useful for aborting multipart uploads that didn't complete or were aborted. For more information, see Abort Multipart Uploads to an S3 Bucket Using the AWS SDK for .NET (High-Level API).
