从HttpWebRequest和HttpWebResponse获取HTTP状态代码编号（200，30

我试图让从HTTP状态代码号HttpWebResponse从返回的对象HttpWebRequest 。 我希望得到实际的数字（200，301,302，404等），而不是文本描述。 （“OK”，“MovedPermanently”等）是响应对象埋在某处财产多少？ 任何想法不是创建一个大的开关功能等？ 谢谢。

HttpWebRequest webRequest = (HttpWebRequest)WebRequest
                                           .Create("http://www.gooogle.com/");
webRequest.AllowAutoRedirect = false;
HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
//Returns "MovedPermanently", not 301 which is what I want.
Console.Write(response.StatusCode.ToString());

Answer 1:

Console.Write((int)response.StatusCode);

HttpStatusCode （类型response.StatusCode ）是其中成员的值匹配HTTP状态代码的枚举，例如

public enum HttpStatusCode
{
    ...
    Moved = 301,
    OK = 200,
    Redirect = 302,
    ...
}

Answer 2:

你必须在4XX和5XX扔引发WebException的范围内谨慎，服务器的响应。 你必须抓住它，然后得到引发WebException对象状态代码：

try
{
    wResp = (HttpWebResponse)wReq.GetResponse();
    wRespStatusCode = wResp.StatusCode;
}
catch (WebException we)
{
    wRespStatusCode = ((HttpWebResponse)we.Response).StatusCode;
}

Answer 3:

按照“DTB”你需要使用HttpStatusCode，但以下“zeldi”你必须要格外小心代码响应> = 400。

这为我工作：

HttpWebResponse response = null;
HttpStatusCode statusCode;
try
{
    response = (HttpWebResponse)request.GetResponse();
}
catch (WebException we)
{
    response = (HttpWebResponse)we.Response;
}

statusCode = response.StatusCode;
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
sResponse = reader.ReadToEnd();
Console.WriteLine(sResponse);
Console.WriteLine("Response Code: " + (int)statusCode + " - " + statusCode.ToString());

Answer 4:

只是要挟StatusCode来int 。

var statusNumber;
try {
   response = (HttpWebResponse)request.GetResponse();
   // This will have statii from 200 to 30x
   statusNumber = (int)response.StatusCode;
}
catch (WebException we) {
    // Statii 400 to 50x will be here
    statusNumber = (int)we.Response.StatusCode;
}

Answer 5:

//Response being your httpwebresponse
Dim str_StatusCode as String = CInt(Response.StatusCode)
Console.Writeline(str_StatusCode)
