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.

Uploads files from a specified directory. The object key is derived from the file names inside the directory. 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:

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 BeginUploadDirectory and EndUploadDirectory.

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

Syntax

C#
public abstract Task UploadDirectoryAsync(
         String directory,
         String bucketName,
         CancellationToken cancellationToken
)
Parameters
directory
Type: System.String

The source directory, that is, the directory containing the files to upload.

bucketName
Type: System.String

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

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: 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.AbortMultipartUploads() to abort the incomplete multipart uploads.
