HTTP Status Codes in C#

I’m in the middle of writing ab WebDAV HttpHandler. Strangely, I could not find a list of HTTP Status Code constants in C# on the web, and transformed the codes from the RFCs myself.

I chose to distinguish between HTTP codes and WebDAV codes. Since WebDAV sits on top of HTTP, they share some codes, so I derived the WebdavStatusCode class from the HttpStatusCode class.

Here they are:

public class HttpStatusCode
{
  protected HttpStatusCode() {}

  // http://www.w3.org/Protocols/rfc2616/rfc2616-sec6.html#sec6.1.1
