C#でネストされたクラスのリストをシリアル化する際に奇妙な問題が発生します。クラスは次のように定義されます
public class Settings : XmlSerializable
{
private string mPath = "";
public string Path
{
get { return mPath; }
set { mPath = value; }
}
[XmlArrayItem("ChatEventsAndReactions")]
public List<MessageEvent> Events;
}
public abstract class XmlSerializable
{
public virtual void Save(string path)
{
StreamWriter w = new StreamWriter(path);
XmlSerializer s = new XmlSerializer(this.GetType());
s.Serialize(w, this);
w.Close();
}
public virtual void Load(string path)
{
if (File.Exists(path))
{
StreamReader sr = new StreamReader(path);
XmlTextReader xr = new XmlTextReader(sr);
XmlSerializer xs = new XmlSerializer(this.GetType());
object c;
if (xs.CanDeserialize(xr))
{
c = xs.Deserialize(xr);
Type t = this.GetType();
PropertyInfo[] properties = t.GetProperties();
foreach (PropertyInfo p in properties)
{
p.SetValue(this, p.GetValue(c, null), null);
}
}
xr.Close();
sr.Close();
}
}
}
クラスMessageEvent
は次のように定義されます
public class MessageEvent
{
public MessageData Message = new MessageData();
public MessageReaction Reaction = new MessageReaction();
public override string ToString()
{
string tmp = this.Message.ToString() + " " + this.Reaction.ToString();
return tmp;
}
}
public class MessageReaction
{
public string ReactionType;
public string Parameter;
public override string ToString()
{
string tmp = "Reaction: " + this.ReactionType + " " +
"Parameter: " + this.Parameter;
return tmp;
}
}
public class MessageData
{
public string ChannelName;
public string ChannelID;
public string SenderName;
public string MessageID;
public string Text;
public MessageData()
{ }
public MessageData(string content)
{
this.ConvertFromString(content);
}
public void Clear()
{
this.ChannelName = "";
this.ChannelID = "";
this.MessageID = "";
this.SenderName = "";
this.Text = "";
}
public void ConvertFromString(string msg)
{
int HeaderEnd = msg.IndexOf("]") + 1;
string Header = msg.Substring(0, HeaderEnd);
string Text = msg.Substring(HeaderEnd);
Header = Header.Replace("[", "");
Header = Header.Replace("]", "");
Header = Header.Replace("\",\"", "\"");
Header = Header.Replace("\",", "\"");
char[] Seperator = { '\"' };
string[] message = Header.Split(Seperator);
this.ChannelName = message[2];
this.ChannelID = message[1];
this.MessageID = message[4];
this.SenderName = message[3];
this.Text = Text;
}
public void ConvertFromObject(object o)
{
MessageData tmp = (MessageData)o;
this.ChannelName = tmp.ChannelName;
this.ChannelID = tmp.ChannelID;
this.SenderName = tmp.SenderName;
this.MessageID = tmp.MessageID;
this.Text = tmp.Text;
}
public override string ToString()
{
return "ChannelID: " + this.ChannelID + " " +
"CannelName: " + this.ChannelName + " " +
"SenderName: " + this.SenderName + " " +
"MessageID : " + this.MessageID + " " +
"Message: " + this.Text;
}
}
それに関する奇妙な問題は、データを保存するときに完全に機能することです(すべてのデータを含む明確なXMLになります)が、XMLファイルから読み取ると、正しい数のアイテムのリストが表示されますが、それらはすべて空です(""
すべての文字列で)。パスは正常に機能します
