This question came up on Twitter. I’m posting the solution here for posterity. How do you read a non-seekable Stream into a byte[]? Specifically, a HttpWebResponse? Like this:

class Program
{
  static void Main(string[] args)
  {
    var request = WebRequest.Create("http://www.scottseely.com/blog.aspx");
    var response = request.GetResponse() as HttpWebResponse;
    var stream = response.GetResponseStream();
    var buffer = new byte[int.Parse(response.Headers["Content-Length"])];
    var bytesRead = 0;
    var totalBytesRead = bytesRead;
    while(totalBytesRead < buffer.Length)
    {
      bytesRead = stream.Read(buffer, bytesRead, buffer.Length - bytesRead);
      totalBytesRead += bytesRead;
    }

    stream.Close();
    Console.WriteLine(Encoding.UTF8.GetString(buffer, 0, totalBytesRead));
  }
}
