I'm implementing an API using WCF and the specification says to return HTTP 429 in certain circumstances.
Normally I'd simply write:
throw new WebFaultException(HttpStatusCode.NotFound);
However the HttpStatusCode enum does not contain a 429.
I can obviously cast to the enum
throw new WebFaultException((HttpStatusCode)429);
However I'm worried that this will not produce the correct result to the application calling my API.
What's the best way to create extend the HttpStatusCode and send valid (but unsupported) HTTP statuses?
The simplest way to fix an HTTP 429 error is to wait to send another request. Often, this status code is sent with a “Retry-after” header that specifies a period of time to wait before sending another request.
The HTTP 429 Too Many Requests response status code indicates the user has sent too many requests in a given amount of time ("rate limiting"). A Retry-After header might be included to this response indicating how long to wait before making a new request.
From the C# Language Specification 5.0:
The set of values that an enum type can take on is not limited by its enum members. In particular, any value of the underlying type of an enum can be cast to the enum type and is a distinct valid value of that enum type.
So this is completely alright to do and would be your best bet:
throw new WebFaultException((System.Net.HttpStatusCode)429);
