C#读写取Xml文件

1.读Xml

XmlDocument doc = new XmlDocument();

doc.Load(xmlFile); //加载Xml文件

XmlElement rootElem = doc.DocumentElement; //获取根节点

XmlNodeList infoNodes = rootElem.GetElementsByTagName("s1");

//遍历 Node

foreach (XmlNode node in infoNodes)

{

string strName = ((XmlElement)node).GetAttribute("name");

}

2.写Xml

XmlDocument xmldoc = null;

XmlElement root = null;

xmldoc = new XmlDocument();

root = xmldoc.CreateElement("book");

XmlElement Xlem = xmldoc.CreateElement(“s1”);

Xlem .SetAttribute("name", "t");

root .AppendChild(Xlem);

xmldoc.Save("1.xml");
