Xml读取和写入以及新建

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>
