AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

This operation aborts a multipart upload. After a multipart upload is aborted, no additional parts can be uploaded using that upload ID. The storage consumed by any previously uploaded parts will be freed. However, if any part uploads are currently in progress, those part uploads might or might not succeed. As a result, it might be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts.

To verify that all parts have been removed, so you don't get charged for the part storage, you should call the ListParts operation and ensure that the parts list is empty.

For information about permissions required to use the multipart upload API, see Multipart Upload API and Permissions.

The following operations are related to AbortMultipartUpload:

Note:

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginAbortMultipartUpload and EndAbortMultipartUpload. For Unity the operation does not take CancellationToken as a parameter, and instead takes AmazonServiceCallback<AbortMultipartUploadRequest, AbortMultipartUploadResponse> and AsyncOptions as additional parameters.

Namespace: Amazon.S3
Assembly: AWSSDK.S3.dll
Version: 3.x.y.z

Syntax

C#
public abstract Task<AbortMultipartUploadResponse> AbortMultipartUploadAsync(
         String bucketName,
         String key,
         String uploadId,
         CancellationToken cancellationToken
)
Parameters
bucketName
Type: System.String

The bucket name to which the upload was taking place. When using this API with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this operation using an access point through the AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using Access Points in the Amazon Simple Storage Service Developer Guide.

key
Type: System.String

Key of the object for which the multipart upload was initiated.

uploadId
Type: System.String

Upload ID that identifies the multipart upload.

cancellationToken
Type: System.Threading.CancellationToken

A cancellation token that can be used by other objects or threads to receive notice of cancellation.
