Desciption

I want to create a HTTP response with custom Status Code (unreserved) 431. I want to modify it's text:

• 200 (OK)
• 400 (Bad Request)
• 431 (My message here)

I've tried:

var response = new HttpResponseMessage() 
{
    StatusCode = (HttpStatusCode) 431,
};

response.Headers.Add("Status Code", "431 My custom text"); // This throws error.

Answer 1

Just add ReasonPhrase in initializer :

        var response = new HttpResponseMessage()
        {
            StatusCode = (HttpStatusCode)431,
            ReasonPhrase = "your text"
        };

It defines text of the message that send with the status code
