Unity中读Xml配置文件

在网上查了一些方法，改改测测写出来的。可能有些地方不太合适或者有隐患，至少目前用起来没什么问题。存一下代码。

Config.cs：

using UnityEngine;
using System.Collections;

using System.Xml;
//using System.IO;


namespace MyConfig
{
    public struct ConfigData
    {
        public int viewMode;
        public int followNum;
        public int planeHeight;
        public int recvPort;
        public string recvIP;
    };


    public class Config
    {
        public ConfigData ReadXML(string fileName)
        {
            ConfigData ret;

            XmlDocument xmlDoc = new XmlDocument();
            //string path = "G:/Test.xml";
            //xmlDoc.Load(path);
            //xmlDoc.Load(Application.dataPath + "/Test.xml");

            //在编辑状态下输出和Asset文件夹同目录的路径，发布状态下得到和生成exe同目录的路径
            string DPath = Application.dataPath;
            int num = DPath.LastIndexOf("/");
            DPath = DPath.Substring(0, num);

            //xmlDoc.Load(DPath + "/UnityConfig.xml");
            xmlDoc.Load(DPath + fileName);

            XmlNode rootNode = xmlDoc.GetElementsByTagName("UnityData")[0];

            //int nodeCount = rootNode.ChildNodes.Count; //根节点下节点数
            //Debug.Log(nodeCount);

            ret.viewMode = XmlConvert.ToInt32(rootNode.ChildNodes[0].InnerText);
            ret.followNum = XmlConvert.ToInt32(rootNode.ChildNodes[1].InnerText);
            ret.planeHeight = XmlConvert.ToInt32(rootNode.ChildNodes[2].InnerText);
            ret.recvPort = XmlConvert.ToInt32(rootNode.ChildNodes[3].InnerText);
            ret.recvIP = rootNode.ChildNodes[4].InnerText;
            //Debug.Log(ret.viewMode);
            //Debug.Log(ret.followNum);
            //Debug.Log(ret.planeHeight);

            return ret;
        }
    }
}

    private Config config = new Config();
    private ConfigData configData;

    //读配置文件
    configData = config.ReadXML("/UnityConfig.xml");

<?xml version="1.0" encoding="utf-8"?>
<UnityData>
	<ViewMode>1</ViewMode>
   	<FollowNum>0</FollowNum>
	<Height>0</Height>
	<RecvPort>2017</RecvPort>
	<RecvIP>127.0.0.1</RecvIP>
</UnityData>

以后有机会学深一点的话再回来修改。
