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.

Note:

For .NET Core this operation is only available in asynchronous form. Please refer to UploadAsync.

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

Syntax

C# 
public virtual void Upload(
         Stream stream,
         String bucketName,
         String key
)

Parameters

stream
Type: System.IO.Stream

The stream to read to obtain the content to upload.

bucketName
Type: System.String

The target Amazon S3 bucket, that is, the name of the bucket to upload the stream to.

key
Type: System.String

The key under which the Amazon S3 object is stored.

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.AbortMultipartUploads() to abort the incomplete multipart uploads.
