Uploads the file or stream specified by the request. To track the progress of the upload, add an event listener to the request's UploadProgressEvent. For large uploads, the file will be divided and uploaded in parts using Amazon S3's multipart API. The parts will be reassembled as one object in Amazon S3.

Namespace: Amazon.S3.Transfer
Assembly: AWSSDK.dll
Version: (assembly version)

Syntax

C# 
public Task UploadAsync(
         TransferUtilityUploadRequest request,
         CancellationToken cancellationToken
)

Parameters

request
Type: Amazon.S3.Transfer.TransferUtilityUploadRequest

Contains all the parameters required to upload to Amazon S3.

cancellationToken
Type: System.Threading.CancellationToken

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

Return Value
Type: System.Threading.Tasks.Task
The task object representing the asynchronous operation.

Remarks

If you are uploading large files, TransferUtility will use multipart upload to fulfill the request. If a multipart upload is interrupted, TransferUtility will attempt to abort the multipart upload. Under certain circumstances (network outage, power failure, etc.), TransferUtility will not be able to abort the multipart upload. In this case, in order to stop getting charged for the storage of uploaded parts, you should manually invoke TransferUtility.AbortMultipartUploadsAsync() to abort the incomplete multipart uploads.
