在c＃（。net）system.net.http中，如何將response.statuscode作為int獲取？不要使用HttpWebRequest和HttpWebResponse

Question

        var hcHandler = new HttpClientHandler();
        //hcHandler.AllowAutoRedirect = false;
        var hc = new HttpClient(hcHandler);
        hc.DefaultRequestHeaders.Add("user-agent", "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)");
        String url = "http://passport.cnblogs.com/login.aspx";
        var task = hc.GetAsync(new Uri(url));
        HttpResponseMessage response = task.Result;

        string statusCode = response.StatusCode.ToString();

我想以整數形式獲取statusCode，我該怎么辦？

Answer 1

HttpResponseMessage.StatusCode是一個HttpStatusCode枚舉，它的底層整數類型是int ，所以你可以把它強制轉換：

int statusCode = (int)response.StatusCode;

Answer 2

HttpStatusCode聲明為枚舉類似：

enum HttpStatusCode
{
     NotFound = 404,
     ...
}

這意味着您只需通過投射即可完成：

int status = (int)HttpStatusCode.NotFound;
