在c＃（。net）system.net.http中，如何将response.statuscode作为int获取？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();

我想以整数形式获取statusCode，我该怎么办？

Answer 1

HttpResponseMessage.StatusCode是一个HttpStatusCode枚举，它的底层整数类型是int ，所以你可以把它强制转换：

int statusCode = (int)response.StatusCode;

Answer 2

HttpStatusCode声明为枚举类似：

enum HttpStatusCode
{
     NotFound = 404,
     ...
}

这意味着您只需通过投射即可完成：

int status = (int)HttpStatusCode.NotFound;
