Uploads the contents of the specified stream. 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.
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 BeginUpload and EndUpload.
public abstract Task UploadAsync( Stream stream, String bucketName, String key, CancellationToken cancellationToken )
The stream to read to obtain the content to upload.
The target Amazon S3 bucket, that is, the name of the bucket to upload the stream to.
The key under which the Amazon S3 object is stored.
A cancellation token that can be used by other objects or threads to receive notice of cancellation.
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.
