C# WebOperationContext.Current.OutgoingResponse.StatusCode不工作

在WCF REST API中，出于某种原因，我想设置自己的状态码-

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

它与客户端完全不同：-

 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;
                }
            }

但是这里resresponse.StatusCode始终是HttpStatusCode.OK

我可以知道原因吗？这里怎么了

添加内容：-

我尝试在Rest服务方法中使用以下内容--

没有必要使用--

有什么建议吗？

在WCF Rest API中，您可以使用

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

抛出新的WebFaultException（，HttpStatusCode.Forbidden）；

@tdelpine，我甚至试图这样做，但问题是，在这种情况下，客户端代码来自“使用（HttpWebResponse response=（HttpWebResponse）restRequest.GetResponse（））”语句并转到我不想要的错误页。您希望该客户端做什么？？？在web.config的system.web部分中将customErrors关闭

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...." 
}

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

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