从HttpWebRequest和HttpWebResponse获取Http状态代码(200、301、404等)

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

HttpStatusCode (一类) response.StatusCode

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

您必须小心,4xx和5xx范围内的服务器响应会引发WebException。您需要捕获它,然后从WebException对象获取状态代码:

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

根据“dtb”,您需要使用HttpStatusCode,但在“zeldi”之后,您需要特别小心代码响应>=400

这对我起了作用:

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());

StatusCode 到 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;
}

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