有时候要用到Xml的读取和写入，甚至有时候需要新建一个Xml，但是好长时间不用这东西，都忘了，所以就写了一个类库，想用的时候直接拿过来用就OK了

下面是代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml;namespace Xmlleiku
{public class Xmllei{public static string xmlpath = string.Empty;/// <summary>/// 初始化xml的物理地址/// </summary>/// <param name="path">物理地址</param>public Xmllei(string path){xmlpath = path;}/// <summary>/// 读取xml中的内容/// </summary>/// <param name="element">节点的名字</param>public Dictionary<int, string[]> Reader(string element){XmlDocument xodc = new XmlDocument();xodc.Load(xmlpath);XmlNodeList lis = xodc.GetElementsByTagName(element);Dictionary<int, string[]> dic = new Dictionary<int, string[]>();int j = 0;foreach (XmlNode item in lis){string[] a = new string[item.ChildNodes.Count];for (int i = 0; i < item.ChildNodes.Count; i++){a[i] = item.ChildNodes.Item(i).InnerText;}dic.Add(j++, a);}return dic;}/// <summary>/// 写入已有的Xml文档/// </summary>/// <param name="element">对应的标签组</param>/// <param name="meirong">与标签对应的内容</param>/// <returns></returns>public int Write(string[] element, List<string[]> meirong){int j=0;try{XmlDocument xodc = new XmlDocument();xodc.Load(xmlpath);foreach (string[] item1 in meirong){int i = 1;XmlElement a = xodc.CreateElement(element[0]);foreach (string item2 in item1){XmlElement b = xodc.CreateElement(element[i++]);b.AppendChild(xodc.CreateTextNode(item2));a.AppendChild(b);}j++;xodc.DocumentElement.AppendChild(a);xodc.Save(xmlpath);}return j;}catch{return 0;}}/// <summary>/// 创建一个新的Xml文档/// </summary>/// <param name="element">包含Xml文档的根目录的标签组</param>/// <param name="meirong">内容数组</param>/// <returns></returns>public int Create(string[] element,List<string[]> meirong){int j = 0;XmlWriterSettings sttingsw = new XmlWriterSettings();sttingsw.Encoding = System.Text.Encoding.UTF8;sttingsw.Indent = true;using (XmlWriter writer = XmlWriter.Create(xmlpath)){writer.WriteStartDocument();writer.WriteStartElement(element[0]);foreach (string[] item1 in meirong){int i = 2;writer.WriteStartElement(element[1]);foreach (string item2 in item1){writer.WriteStartElement(element[i++]);writer.WriteString(item2);writer.WriteEndElement();}writer.WriteEndElement();j++;}writer.WriteEndElement();writer.WriteEndDocument();}return j;}}
}
