C# 读取xml - .NET技术 / C#

C# code:
strXml="
<ListConferenceResponse xmlns="http://mediax.huawei.com/webservice/types">
<code xmlns="">200</code>
<description xmlns="">Success</description>
</ListConferenceResponse>
";

XmlDocument xmlDocument = new XmlDocument();
xmlDocument.LoadXml(str);
XmlNode xmlNode = xmlDocument.SelectSingleNode("LoginResponse/code");
strResult = xmlNode.InnerText;


为什么获取的 xmlNode 是null

---

XmlNode xmlNode = xmlDocument.SelectSingleNode("//LoginResponse/code");

---

因为XmlNode xmlNode = xmlDocument.SelectSingleNode("LoginResponse/code");
code下没有子节点了……

---

LoginResponse 和ListConferenceResponse 是什么关系啊

---

LoginResponse 改到 ListConferenceResponse

---

XmlNode xmlNode = xmlDocument.DocumentElement.SelectSingleNode("code");

---

string strXml="<ListConferenceResponse xmlns='http://mediax.huawei.com/webservice/types'>"+
"<code xmlns=''>200</code>"+
"<description xmlns=\"\">Success</description>"+
"</ListConferenceResponse>";

XmlDocument xmlDocument = new XmlDocument();
xmlDocument.LoadXml(strXml);//这里的参数你写成了str

XmlNode xmlNode = xmlDo
