C#简单写入xml文件的方法

static void writeTree(XmlNode xmlElement, int level) {  String levelDepth = "";  for(int i=0;i<level;i++)   {   levelDepth += "  ";  }  Console.Write("/n{0}<{1}",levelDepth,xmlElement.Name);  XmlAttributeCollection xmlAttributeCollection = xmlElement.Attributes;  foreach(XmlAttribute x in xmlAttributeCollection)   {   Console.Write(" {0}='{1}'",x.Name,x.Value);  }  Console.Write(">");  XmlNodeList xmlNodeList = xmlElement.ChildNodes;  ++level;  foreach(XmlNode x in xmlNodeList)   {   if(x.NodeType == XmlNodeType.Element)    {     writeTree((XmlNode)x, level);   }   else if(x.NodeType == XmlNodeType.Text)    {     Console.Write("/n{0}  {1}",levelDepth,(x.Value).Trim());   }  }  Console.Write("/n{0}</{1}>",levelDepth,xmlElement.Name);}
