Create A Console Application And Write Code

Create a console application and install "AWSSDK.S3" from Nuget. In the "Program.cs" file, write the following code.

using Amazon;
using Amazon.Runtime;
using Amazon.S3;
using Amazon.S3.Transfer;
using System.IO;

namespace dotnetS3
{
    class Program
    {

        public static void Main(string[] args)
        {

            string bucketName = "gyansangrah-bucket";

            UploadFilesAndFolder(bucketName);
        }

        static void UploadFilesAndFolder(string bucketName)
        {
            var region = RegionEndpoint.GetBySystemName("us-east-2");
            AWSCredentials credentails = new BasicAWSCredentials("<Access Id>", "<Secret Key>");

            AmazonS3Client client = new AmazonS3Client(credentails);

            TransferUtility utility = new TransferUtility(client);
            TransferUtilityUploadDirectoryRequest transferUtilityUploadDirectoryRequest
                = new TransferUtilityUploadDirectoryRequest()
                {
                    BucketName = bucketName,
                    Directory = @"C:\temp\cluster",
                    SearchOption = SearchOption.AllDirectories
                };

            utility.UploadDirectory(transferUtilityUploadDirectoryRequest);
        }

       

    }
}
