Hi Eric,
using (StreamReader fileStream = new StreamReader(FileUpload1.PostedFile.InputStream))
{
fileBytes = Encoding.UTF8.GetBytes(fileStream.ReadToEnd());
fileStream.Close();
}
Replace above with the below code.
Stream fs = FileUpload1.PostedFile.InputStream;
BinaryReader br = new BinaryReader(fs);
fileBytes = br.ReadBytes((Int32)fs.Length);
