To upload multiple files to an AWS S3 bucket and get the URLs of the uploaded files in C# you can use the AWS SDK for .NET. Below is an example of how to do this: using System; using System.Collections.Generic; using System.Threading.Tasks; using Amazon; using Amazon.S3; using Amazon.S3.Model; namespace S3UploadExample { class Program { private const string bucketName = YOUR_BUCKET_NAME; private static readonly RegionEndpoint bucketRegion = RegionEndpoint.YOUR_REGION; private static IAmazonS3 s3Client; static async Task Main(string[] args) { s3Client = new AmazonS3Client(bucketRegion); List filePaths = new List { FILE_PATH_1 FILE_PATH_2 // Add more file paths as needed }; foreach (var filePath in filePaths) { await UploadFileAsync(filePath); } } private static async Task UploadFileAsync(string filePath) { try { var fileTransferUtility = new TransferUtility(s3Client); var keyName = YOUR_PREFIX/ + Guid.NewGuid() + System.IO.Path.GetExtension(filePath); var fileTransferUtilityRequest = new TransferUtilityUploadRequest { BucketName = bucketName FilePath = filePath Key = keyName CannedACL = S3CannedACL.PublicRead }; await fileTransferUtility.UploadAsync(fileTransferUtilityRequest); var url = GeneratePreSignedURL(bucketName keyName); Console.WriteLine($File upload successful. URL: {url}); } catch (AmazonS3Exception e) { Console.WriteLine(Error encountered on server. Message:'{0}' when writing an object e.Message); } catch (Exception e) { Console.WriteLine(Unknown encountered on server. Message:'{0}' when writing an object e.Message); } } private static string GeneratePreSignedURL(string bucketName string objectKey) { var request = new GetPreSignedUrlRequest { BucketName = bucketName Key = objectKey Expires = DateTime.Now.AddHours(1) }; string url = s3Client.GetPreSignedURL(request); return url; } } }
