asp.net解析xml的笔记
一个小游戏里的例子，游戏里面商品的属性通过XML写成配置文件，这样方便修改物品的属性和修改所有商品。
1.XML文件
<?xml version="1.0" encoding="utf-8" ?>
<!--
商品属性
ID:商品ID，唯一值
Type：商品分类：food-表示食品，toy-表示玩具，cosmetics-表示化妆品，drug-表示药品
Time:使用次数
Effect:使用效果，表示形式：饥饿指数|清洁指数|健康指数|心情指数|魅力指数|智力指数|经验值
IsSale:是否出售，0表示没出售，1表示在出售
-->
<store>
<Item>
<ID>1</ID>
<Type>food</Type>
<Name>强力丸</Name>
<Price>10</Price>
<Times>5</Times>
<Effect>20|0|0|0|0|0|5</Effect>
<IsSale>1</IsSale>
</Item>
<Item>
<ID>2</ID>
<Type>toy</Type>
<Name>足球</Name>
<Price>20</Price>
<Times>5</Times>
<Effect>0|0|0|10|0|20|5</Effect>
<IsSale>1</IsSale>
</Item>
</store>
2.封装好的物品属性
/// <summary>
/// 商品列表类
/// </summary>
public class StoreItem
{
private int Id;
private string itemName;
private string itemType;
private int itemPrice;
private int itemTimes;
private string itemEffect;
private bool isSale;
/// <summary>
/// 商品ID
/// </summary>
public int ID
{
get { return Id; }
set { Id = value; }
}
/// <summary>
/// 商品名称
/// </summary>
public string ItemName
{
get { return itemName; }
set { itemName = value; }
}
/// <summary>
/// 商品类型
/// </summary>
public string ItemType
{
get { return itemType; }
set { itemType = value; }
}
/// <summary>
/// 商品价格
/// </summary>
public int ItemPrice
{
get { return itemPrice; }
set { itemPrice = value; }
}
/// <summary>
/// 使用次数
/// </summary>
public int ItemTimes
{
get { return itemTimes; }
set { itemTimes = value; }
}
/// <summary>
/// 使用效果
/// </summary>
public string ItemEffect
{
get { return itemEffect; }
set { itemEffect = value; }
}
/// <summary>
/// 是否出售
/// </summary>
public bool IsSale
{
get { return isSale; }
set { isSale = value; }
}
public override string ToString()
{
return "<br/>ID:" + Id + "<br/>Name:" + itemName + "<br/>Type:" + itemType + "<br/>Effect:" + itemEffect +"<br/>Price:" + itemPrice + "<br/>Times:" + itemTimes + "<br/>IsSale:" + isSale;
}
}
3.封装物品的疗效
/// <summary>
/// 物品的疗效，表示增加属性的点数
/// </summary>
public struct StoreItemEffect
{
private int hunger;
/// <summary>
/// 增加饥饿点数
/// </summary>
public int Hunger
{
get { return hunger; }
set { hunger = value; }
}
private int clean;
/// <summary>
/// 增加清洁点数
/// </summary>
public int Clean
{
get { return clean; }
set { clean = value; }
}
private int health;
/// <summary>
/// 增加健康点数
/// </summary>
public int Health
{
get { return health; }
set { health = value; }
}
private int mood;
/// <summary>
/// 增加心情点数
/// </summary>
public int Mood
{
get { return mood; }
set { mood = value; }
}
private int charm;
/// <summary>
/// 增加魅力点数
/// </summary>
public int Charm
{
get { return charm; }
set { charm = value; }
}
private int smart;
/// <summary>
/// 增加智力点数
/// </summary>
public int Smart
{
get { return smart; }
set { smart = value; }
}
private int experience;
/// <summary>
/// 增加经验点数
/// </summary>
public int Experience
{
get { return experience; }
set { experience = value; }
}
public override string ToString()
{
return "<br/>饥饿+" + hunger + "<br/>清洁+" + clean + "<br/>健康+" + health + "<br/>心情+" + mood + "<br/>魅力+" + charm + "<br/>智力+" + smart + "<br/>经验+" + experience;
}
}
4.解析物品文件，返回商品字典
/// <summary>
/// 商店配置表路径
/// </summary>
private readonly static string configPath = HttpContext.Current.Server.MapPath("/config/store.xml");
/// <summary>
/// 获取商品列表
/// </summary>
/// <returns>商品列表</returns>
public static Dictionary<int,StoreItem> getStoreItem()
{
StoreItem stoItem;
Dictionary<int, StoreItem> Dict = new Dictionary<int, StoreItem>();
XmlDocument xml = new XmlDocument();
xml.Load(configPath);
XmlNodeList rootList = xml.SelectNodes("g");
foreach (XmlNode xn in rootList)
{
stoItem = new StoreItem();
stoItem.ID = int.Parse(xn.ChildNodes[0].InnerText);
stoItem.ItemName = xn.ChildNodes[2].InnerText;
stoItem.ItemType = xn.ChildNodes[1].InnerText;
stoItem.ItemPrice = int.Parse(xn.ChildNodes[3].InnerText);
stoItem.ItemTimes = int.Parse(xn.ChildNodes[4].InnerText);
stoItem.ItemEffect = xn.ChildNodes[5].InnerText;
if (xn.ChildNodes[6].InnerText.Trim() == "1")
stoItem.IsSale = true;
else
stoItem.IsSale = false;
Dict.Add(stoItem.ID, stoItem);
}
return Dict;
}
5.通过物品ID返回相应物品的疗效数值
/// <summary>
/// 根据物品ID返回相应物品的疗效值
/// </summary>
/// <param name="stoItemID">表示传入商品ID</param>
/// <returns>物品疗效值</returns>
public static StoreItemEffect getItemEffect(int stoItemID)
{
Dictionary<int, StoreItem> Dict = new Dictionary<int, StoreItem>();
Dict = getStoreItem();
string[] effect=Dict[stoItemID].ItemEffect.Split('|');
StoreItemEffect stoIEffect = new StoreItemEffect();
stoIEffect.Hunger = int.Parse(effect[0].ToString());
stoIEffect.Clean = int.Parse(effect[1].ToString());
stoIEffect.Health = int.Parse(effect[2].ToString());
stoIEffect.Mood = int.Parse(effect[3].ToString());
stoIEffect.Charm = int.Parse(effect[4].ToString());
stoIEffect.Smart = int.Parse(effect[5].ToString());
stoIEffect.Experience = int.Parse(effect[6].ToString());
return stoIEffect;
}
