Try below code..
   public void DownloadS3BuketObject(string nameoffile)
   {
       RegionEndpoint bucketRegion = RegionEndpoint.USEast1;
       IAmazonS3 client = new AmazonS3Client(bucketRegion);

       string accessKey = System.Configuration.ConfigurationManager.AppSettings["S3AccessKey"];
       string secretKey = System.Configuration.ConfigurationManager.AppSettings["S3SecretKey"];

       AmazonS3Client s3Client = new AmazonS3Client(new BasicAWSCredentials(accessKey, secretKey), Amazon.RegionEndpoint.USEast1);
       string objectKey = "EMR" + "/" + nameoffile;

       //EMR is folder name of the image inside the bucket
       GetObjectRequest request = new GetObjectRequest();
       request.BucketName = System.Configuration.ConfigurationManager.AppSettings["bucketname"];
       request.Key = objectKey;
       GetObjectResponse response = s3Client.GetObject(request);

       response.WriteResponseStreamToFile("D:\\SharedFolder\\"+ nameoffile);
// Path of your shared folder to downloaf

   }
Hope this makes sense!

file path will be your shared folder path, then you can return a static path like /shared/filename
TransferUtility fileTransferUtility =
    new TransferUtility(
        new AmazonS3Client("ACCESS-KEY-ID", "SECRET-ACCESS-KEY", Amazon.RegionEndpoint.YourRegion));

// Note the 'fileName' is the 'key' of the object in S3 (which is usually just the file name in your case image name)
fileTransferUtility.Download(filePath, "my-bucket-name", fileName);
