的XPath C＃属性值

Question

以下是（ “2015”）存储在某个文本框

读入的XmlDocument

<Test xmlns="http://api.test.com/v2" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> 
    <Result id="2015" description="Invalid Token" /> 
</Test > 

我需要的是 'id' 属性值的XML文件，这是多么的XmlDocument被加载

XmlDocument updateUser = new XmlDocument(); 
updateUser.Load(response.GetResponseStream()); 

很好地工作到这里。

然后，创建命名空间和搜索节点

XmlNamespaceManager nsmgr = new XmlNamespaceManager(updateUser.NameTable); 
nsmgr.AddNamespace("restup", "http://api.test.com/v2"); 

XmlNodeList locationElements1 = updateUser.SelectNodes("//restup:Test", nsmgr); 
foreach (XmlNode Test in locationElements1) 
{ 
//What DO I do here to get the value of 'id' attribute from the 'Result' node and save it in txtTest Textbox. 

} 

Answer 1

string idString = Test.FirstChild.Attributes["id"].ToString(); 

Answer 2

var id = Test.FirstChild.Attributes["id"].Value; 

Answer 3

您好，这是可以

XmlTextReader reader = new XmlTextReader(fileLocation); //fileLocation is the Path of the XML file 
while (reader.Read()) 
{ 

    if (reader.NodeType == XmlNodeType.Element) //if the node is an element (not a comment, CDATA, or text) 
    if (reader.Name == "Result") 
     textBox1.Text = reader.GetAttribute("id"); 

} 
reader.Close();
