【C#】如何创建xml文件以及xml文件的增、改

增：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text.RegularExpressions;

using System.Web;

using System.Xml;

namespace AppService

{

    public class XMLReader

    {

        public static void XMLMake(string inDesString)

        {

            try

            {

                string s = inDesString;

                string[] resultString = s.Split('|');

                foreach (string i in resultString)

                {

                }

                XmlDocument doc = new XmlDocument();

                XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", "UTF-8", null);

                doc.AppendChild(dec);

                //创建一个根节点（一级）

                XmlElement root = doc.createElement_x("jokes");

                doc.AppendChild(root);

                //创建节点（二级）

                XmlNode node = doc.createElement_x("tag");

                //创建节点（三级）

                XmlElement element1 = doc.createElement_x("shenchang");

                //element1.SetAttribute("Name", "Sam");

                //element1.SetAttribute("ID", "665");

                element1.InnerText = resultString[];

                node.AppendChild(element1);

                XmlElement element2 = doc.createElement_x("tizhong");

                //element2.SetAttribute("Name", "Round");

                //element2.SetAttribute("ID", "678");

                element2.InnerText = resultString[];

                node.AppendChild(element2);

                XmlElement element3 = doc.createElement_x("bmi");

                //element2.SetAttribute("Name", "Round");

                //element2.SetAttribute("ID", "678");

                element3.InnerText = resultString[];

                node.AppendChild(element3);

                root.AppendChild(node);

                string p = AppDomain.CurrentDomain.BaseDirectory + "Version1";

                doc.Save(p + "\\ABC.xml");

                Console.Write(doc.OuterXml);

            }

            catch

            { }

        }

    }

}

改:

        public static void XMLUpdate(String inDesString)

        {

            string s = inDesString;

            string[] resultString = s.Split('|');

            try

            {

                XmlDocument xmlDoc = new XmlDocument();

                string p = AppDomain.CurrentDomain.BaseDirectory + "Version1";

                xmlDoc.Load(p + "\\ABC.xml");

                XmlNode xns = xmlDoc.SelectSingleNode("jokes");

                XmlNodeList xnl = xns.ChildNodes;

                foreach (XmlNode xn in xnl)

                {

                    XmlElement xe = (XmlElement)xn;

                    XmlNodeList xnl2 = xe.ChildNodes;

                    foreach (XmlNode xn2 in xnl2)

                    {

                        XmlElement xe2 = (XmlElement)xn2;

                        if (xe2.Name == "shenchang")

                        {

                            xe2.InnerText = resultString[];

                        }

                        if (xe2.Name == "tizhong")

                        {

                            xe2.InnerText = resultString[];

                        }

                        if (xe2.Name == "bmi")

                        {

                            xe2.InnerText = resultString[];

                        }

                    }

                }

                xmlDoc.Save(p + "\\ABC.xml");

            }

            catch

            {

            }

        }
