c# streamReader轉XmlDocument讀取節點

http獲得web（url）請求，先是獲得數據流streamreader，之后將String數據流轉換為xmldocument，之后xmlnode讀取節點。

                // get the responseWebResponse webResponse = webRequest.GetResponse();if (webResponse == null){ return null; }//需要將返回的編碼進行指定，指定成默認的即可StreamReader sr = new StreamReader(webResponse.GetResponseStream(), System.Text.Encoding.UTF8);string streamString = sr.ReadToEnd().Trim().Replace("\n", "");//去掉換行符XmlDocument doc = new XmlDocument();doc.LoadXml(streamString);//加載文檔XmlNode test1 = doc.SelectSingleNode("returnsms");//根節點string aaa = test1.SelectSingleNode("returnstatus").InnerText;//子節點
