如何在请求后捕获REST API发送的响应令牌?

我正在使用REST API,我正在使用基本身份验证,其中密码编码为Base64,如下所示

 private XmlDocument sendXMLRequest(string requestXml)
    {
        string destinationUrl = "https://serviceapi.testgroup.com/testtp/query";

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
        request.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("API_TEST_NR:Testnol1$"));
        byte[] bytes;
        bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
        request.Method = "POST";

        request.ContentLength = bytes.Length;
        //request.Connection = "keep-alive";
        request.ContentType = "text/xml";
        request.KeepAlive = true;
        request.Timeout = 2000;
        request.MediaType = "text/xml";
        Stream requestStream = request.GetRequestStream();
        requestStream.Write(bytes, 0, bytes.Length);
        requestStream.Close();
        HttpWebResponse response;
        Stream responseStream;

        using (response = (HttpWebResponse)request.GetResponse())
        {
            if (response.StatusCode == HttpStatusCode.OK)
            {
                responseStream = response.GetResponseStream();
                XmlReader reader = new XmlTextReader(responseStream);

                XmlDocument xmlDoc = new XmlDocument();
                xmlDoc.Load(reader);


                try { reader.Close(); }
                catch { }
                try { responseStream.Close(); }
                catch { }
                try { response.Close(); }
                catch { }
                return xmlDoc;
            }
        }
        try { response.Close(); }
        catch { }
        return null;
    } 

我在Web Api上工作时有点新鲜,我知道在基于API文档成功授权后,API会使用访问x令牌进行响应,而我不确定如何访问或从HTTP标头中捕获它。

我可以知道一个很好的方法吗?

这比我想象的更容易。

string xtoken= response.Headers["custom-header"];
Console.WriteLine(xtoken);

尝试如下所示,使用WebRequest类表示请求数据。在大多数情况下,WebRequest类足以接收数据。但是,如果需要设置特定于协议的属性,则必须将WebRequest强制转换为特定于协议的类型。例如,要访问HttpWebRequest的HTTP特定属性,请将WebRequest强制转换为HttpWebRequest引用。
