c# - WebOperationContext.Current.OutgoingResponse.StatusCode 不工作

Question

在 WCF REST API 中，出于某种原因我想设置自己的 StatusCode -

 WebOperationContext.Current.OutgoingResponse.StatusCode = HttpStatusCode.Forbidden (or any other statuscode)

它在客户端根本不起作用:-

 using (HttpWebResponse restResponse = (HttpWebResponse)restRequest.GetResponse())
            {
                if (restResponse.StatusCode != HttpStatusCode.OK)
                {


                    retVal = String.Format("Request failed. Received HTTP {0}, Description : {1}", restResponse.StatusCode, restResponse.StatusDescription);
                    return retVal;
                }

                using (var st = restResponse.GetResponseStream())
                {
                    StreamReader sr = new StreamReader(st);
                    retVal = sr.ReadToEnd();
                    return retVal;
                }
            }

但这里的 restResponse.StatusCode 总是 HttpStatusCode.OK。

我可以知道原因吗？这里有什么问题？

对它的补充:-

我尝试在 Rest 服务方法中使用以下内容 --

throw new WebFaultException<string>(<...Your message....>, HttpStatusCode.Forbidden );

但这种方法的问题在于，在客户端......它使代码从

Try
{

    using (HttpWebResponse restResponse = (HttpWebResponse)restRequest.GetResponse())
                {
                    if (restResponse.StatusCode != HttpStatusCode.OK)
                    {


                        retVal = String.Format("Request failed. Received HTTP {0}, Description : {1}", restResponse.StatusCode, restResponse.StatusDescription);
                        return retVal;
                    }

                    using (var st = restResponse.GetResponseStream())
                    {
                        StreamReader sr = new StreamReader(st);
                        retVal = sr.ReadToEnd();
                        return retVal;
                    }
                }
}
catch
{
    //it comes here when using "throw new WebFaultException...." 
}

没有意义使用 --

retVal = String.Format("Request failed. Received HTTP {0}, Description : {1}", restResponse.StatusCode, restResponse.StatusDescription);
return retVal;

有什么建议吗？

在 WCF Rest API 中你可以使用这个

throw new WebFaultException<string>(<...Your message....>, HttpStatusCode.Forbidden );
