为了好玩,我正在尝试开发一个简单的RPG。我希望我的游戏能够使用XML文件,以便玩家可以轻松定制游戏。
我有一个种族类和一个带有所有种族静态列表的raceManager类。 我开始使用XmlAttributs(XmlRoot,XmlElement ...)和默认的序列化程序将可播放的比赛写入Xml。
XmlSerializer xs = new XmlSerializer(managedList.GetType());
using (FileStream fs = new FileStream(filePath, FileMode.Create))
{
xs.Serialize(fs, managedList);
}
它有效,但在我的比赛课上,我有技能列表,武器可用...... 默认的序列化程序生成包含这些类的所有属性的数组。
由于我只想要每个对象的单个实例,所以我开始实现IXmlSerializable接口,以便在我阅读时只写入id和检索对象。
现在Xml文件几乎就像我想要的那样:
<?xml version="1.0"?>
<ArrayOfRace xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Race>
<NameMale>Human</NameMale>
...
<ArmorsTypesAllowed>
<ArmorType>Cloth</ArmorType>
<ArmorType>Leather</ArmorType>
<ArmorType>Metal</ArmorType>
</ArmorsTypesAllowed>
</Race>
<Race>
<NameMale>Dwarf</NameMale>
...
</Race>
...
但我再也看不懂了:'(
我使用我的经理方法(之前工作正常):
protected static List<T> ReadFile(string filePath)
{
List<T> ManagedList = new List<T>();
XmlSerializer xs = new XmlSerializer(ManagedList.GetType());
using (FileStream fs = new FileStream(filePath, FileMode.Open))
{
ManagedList = (List<T>)xs.Deserialize(fs);
}
return ManagedList;
}
使用ReadXml方法但返回1个元素的列表(最后一个)。 看起来整个文件(包含列表)发送到我的ReadXml,它假设只读取该列表中的一个元素。
public void ReadXml(XmlReader reader)
{
while(!reader.EOF)
{
if(reader.NodeType == XmlNodeType.Element)
{
switch(reader.Name)
{
case "NameMale":
NameMale = reader.ReadElementContentAsString();
break;
case "NameFemale":
NameFemale = reader.ReadElementContentAsString();
break;
...
default:
reader.Read();
break;
}
}
else
{
reader.Read();
}
}
}
我认为我应该阻止读者。所以我添加了以下代码,但它没有解决我的问题(只有第一场比赛用这个检索)
if(reader.NodeType == XmlNodeType.EndElement && reader.Name == "Race")
{
return;
}

答案 0 :(得分:1)
最后,我发现了自己的错误。 实际上,整个列表只使用一个阅读器。如果在读取对象结束时它不在正确的位置,则读取将停止而不会抛出异常。
我用:
修改了我的循环while(reader.NodeType != XmlNodeType.EndElement || reader.Name != "MyClass")
在该循环结束时,我添加了reader.Read();
跳过</MyClass>
并位于列表中下一个元素(或文件末尾)的开头。
