Getting object size from C# AWS SDK without downloading it

gistfile1.cs

using (var amazonClient = new AmazonS3Client())
{
  var getObjectMetadataRequest = new GetObjectMetadataRequest() { BucketName = RawBucketName, Key = fileName };
  var meta = amazonClient.GetObjectMetadata(getObjectMetadataRequest);
  var fileSize = meta.Headers.ContentLength;
}

Thank you
