Deploy C# client application (S3) with Amazon AWS secret key?

Question

I've written my hello world AWS program today - simple file upload to a premade S3 bucket.

In the context of this program deployed to a client desktop (for arguments sake), is my Secret Access Key safe?

using (AmazonS3Client a = new AmazonS3Client("MyAccessKey", "MySecretAccessKey")) {

            foreach (ListViewItem lvi in listView1.Items)
            {
                TransferUtilityUploadRequest tr = new TransferUtilityUploadRequest()
                .WithBucketName("test_mydomain_com")
                .WithFilePath(((FileInfo)lvi.Tag).FullName)
                .WithTimeout(5 * 60 * 1000);
                TransferUtility tu = new TransferUtility(a);

                tu.Upload(tr);

                MessageBox.Show("Win!");
            }


        }

In short, no - not really. See this question Storing My Amazon Credentials in C# Desktop App which expands on why and what you can do about it.
