Most likely this is a Base64-encoded string, but you should check the S3 documentation to be sure. If it is, you should use Convert.ToBase64String() and pass it the byte array.

Here's some sample code you can try. I haven't tested it, but it should help you get the right idea:

if (Request.Files.Count >= 1) {
    var file = Request.Files[0];
    var fileContents = new byte[file.ContentLength];
    file.InputStream.Read(fileContents, 0, file.ContentLength);
    var fileBase64String = Convert.ToBase64String(fileContents);

    // now you can send fileBase64String to the S3 uploader
}
