Use multipart upload for file size greater 20 MB. Var transferUtilit圜onfig = new TransferUtilit圜onfig Var s3Client = new AmazonS3Client(credentials,RegionEndpoint.USWest2) Public async Task UploadFile(IStorageFile storageFile, string bucket, string key, AWSCredentials credentials, CancellationToken cancellationToken) private const int MB_SIZE = (int)Math.Pow(2, 20) You can also see that we subscribe to TransferUtilityUploadRequest.UploadProgressEvent to receive upload progress notification events. We have changed the part size to 10 MB for multipart upload using the TransferUtilityUploadRequest.PartSize property. We use an instance of the TransferUtilit圜onfig class to change the default values for ConcurrentServiceRequests and MinSizeBeforePartUpload. The following code snippet shows the TransferUtility.UploadAsync method being used to upload a file. This article provides information on working with File Pickers for the Windows Store platform. You can use File Pickers available on these platforms to get an instance of IStorageFile. Notice that we use the IStorageFile type available on Windows Store and Windows Phone platforms. The code snippets in the following sections show how to upload and download a file using TransferUtility.
Another point to note is that these platforms support only the asynchronous APIs. NET 4.5 platforms except for the upload/download directory functionality. The set of TransferUtility API available for Windows Store and Windows Phone platforms includes all the methods available for. It includes support for automatic switching to multipart upload for large files, multi-threaded uploads, cancellation of in-progress operations and notifications for transfer progress. TransferUtility is an API that runs on top of the low-level Amazon S3 API and provides utility methods for uploading and downloading files and directories.
