解决方案
以下是一些供您参考的例子---
1.使用XMLDocument -
public static class XMLParserByXMLDocument
{
private static string xmlUrl = http：// localhost：7467 / xmlDocument.xml;
// 使用XMLDocument类解析xml。
public static SomeClassParseByXMLDocument（）
{
var X = new InformationA（）;
XmlDocument doc = new XmlDocument（）;
doc.Load（xmlUrl）;
XmlNode InformationBNode = doc.SelectSingleNode（ / InformationA / InformationB）;
A.School = InformationBNode.SelectSingleNode（ X）。InnerText;
A.Department = InformationBNode.SelectSingleNode（ Y）。InnerText;
XmlNode AListNode = doc.SelectSingleNode（ / InformationA / listA）;
XmlNodeList ANodeList = AListNode.SelectNodes（ A）;
foreach （XmlNode节点 in AListNode）
{
A aA = new A（）;
aA.id = Convert.ToInt16（node.Attributes
.GetNamedItem（ id).Value）;
aA.name = node.InnerText;
A.Alist.Add（aA）;
}
返回 A;
}
2.使用XDocument -
// 使用XDocument类解析XML。
public static InformationA ParseByXDocument（）
{
var A = new InformationA（）;
XDocument doc = XDocument.Load（xmlUrl）;
XElement generalElement = doc
.Element（ InformationA）
.Element（ InformationB）;
A.School = generalElement.Element（ X）。
A.Department = generalElement.Element（ Y）。
A.Alist =（来自 c doc.Descendants（ A）
select < span class =code-keyword> new A（）
{
id = Convert.ToInt16（c.Attribute（ id）。值），
name = c.Value，
}）。ToList< a>（）;
返回 A;
}
}
}
3.使用XmlReader类 -
XmlReader xmlReader = XmlReader.Create（ http://www.xxxx.net/.../。 ../ XmlRead.xml）;
while （xmlReader.Read（））
{
if （（xmlReader.NodeType == XmlNodeType.Element）&&（xmlReader.Name == XmlRead））
{
if （xmlReader.HasAttributes）
Console.WriteLine（xmlReader.GetAttribute（ ....）+ ： + xmlReader.GetAttribute（ ...））;
}
} < / a >
I need to parse below xml file.Can anyone guide me

解决方案
Here are some examples for your reference ---
1. By Using XMLDocument --
public static class XMLParserByXMLDocument { private static string xmlUrl = "http://localhost:7467/xmlDocument.xml"; // Parse the xml using XMLDocument class. public static SomeClassParseByXMLDocument() { var X = new InformationA(); XmlDocument doc = new XmlDocument(); doc.Load(xmlUrl); XmlNode InformationBNode = doc.SelectSingleNode("/InformationA/InformationB"); A.School = InformationBNode.SelectSingleNode("X").InnerText; A.Department = InformationBNode.SelectSingleNode("Y").InnerText; XmlNode AListNode = doc.SelectSingleNode("/InformationA/listA"); XmlNodeList ANodeList = AListNode.SelectNodes("A"); foreach (XmlNode node in AListNode) { A aA = new A(); aA.id = Convert.ToInt16(node.Attributes .GetNamedItem("id").Value); aA.name = node.InnerText; A.Alist.Add(aA); } return A; }
2. By using XDocument --
// Parse the XML using XDocument class. public static InformationA ParseByXDocument() { var A = new InformationA(); XDocument doc = XDocument.Load(xmlUrl); XElement generalElement = doc .Element("InformationA") .Element("InformationB"); A.School = generalElement.Element("X").Value; A.Department = generalElement.Element("Y").Value; A.Alist = (from c in doc.Descendants("A") select new A() { id = Convert.ToInt16(c.Attribute("id").Value), name = c.Value, }).ToList<a>(); return A; } } }
3. By using XmlReader Class –
XmlReader xmlReader = XmlReader.Create("http://www.xxxx.net/.../.../ XmlRead.xml"); while(xmlReader.Read()) { if((xmlReader.NodeType == XmlNodeType.Element) && (xmlReader.Name == " XmlRead ")) { if(xmlReader.HasAttributes) Console.WriteLine(xmlReader.GetAttribute("….") + ": " + xmlReader.GetAttribute("…")); } }</a>
