Example of Seriazable List

 如果class中包含List<KeyValuePair> abc property，xml不会自动seriaze 这个item。 只能得到<abc/>

根据上一篇的启发，实现了类似功能的List class， 代码如下：

5. public class SeriazableList<TValue>:List<TValue>, IXmlSerializable
6.     {
7.         #region IXmlSerializable Members
9.         public System.Xml.Schema.XmlSchema GetSchema()
10.         {
11.             return null;
12.         }
14.         public void ReadXml(System.Xml.XmlReader reader)
15.         {
16.             XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue));
17.             bool wasEmpty = reader.IsEmptyElement;
19.             reader.Read();
20.             if (wasEmpty)
21.                 return;
22.             while (reader.NodeType != System.Xml.XmlNodeType.EndElement)
23.             {
24.                 TValue value = (TValue)valueSerializer.Deserialize(reader);
25.                 this.Add(value);
26.                 reader.MoveToContent();
27.             }
28.             reader.ReadEndElement();
29.         }
31.         public void WriteXml(System.Xml.XmlWriter writer)
32.         {
33.             XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue));
35.             foreach (TValue value in this)
36.             {
37.                 valueSerializer.Serialize(writer, value);
38.             }  
40.         }
42.         #endregion
43.     }
44.     public struct DynamicParameter:IXmlSerializable
45.     {
46.         public string Name;
47.         public double Value;
48.         public DynamicParameter(string name, double value)
49.         {
50.             this.Name = name;
51.             this.Value = value;
52.         }
54.         #region IXmlSerializable Members
56.         public System.Xml.Schema.XmlSchema GetSchema()
57.         {
58.             return null;
59.         }
61.         public void ReadXml(System.Xml.XmlReader reader)
62.         {
63.             XmlSerializer keySerializer = new XmlSerializer(typeof(string));
64.             XmlSerializer valueSerializer = new XmlSerializer(typeof(double));
65.             bool wasEmpty = reader.IsEmptyElement;
66.             reader.Read();
67.             if (wasEmpty)
68.                 return;
70.             Name = reader.Name;
71.             reader.ReadStartElement();
72.             Double.TryParse(reader.ReadString(), out Value);
73.             reader.ReadEndElement();
74.             reader.MoveToContent();
75.             reader.ReadEndElement();
76.         }
78.         public void WriteXml(System.Xml.XmlWriter writer)
79.         {
80.             writer.WriteStartElement(Name);
81.             writer.WriteValue(Value);
82.             writer.WriteEndElement();
83.         }
85.         #endregion
86.     }

两个类，一个是serialazable List, 另一个是serialazable item。

和上篇的例子相比，这样实现的Node比较紧凑。

这样生成的XML file：

100. <DynamicVariables>
101.   <DynamicParameter>
102.     <OutputIndex>1</OutputIndex> 
103.   </DynamicParameter>
104.   <DynamicParameter>
105.     <ABC>0</ABC> 
106.   </DynamicParameter>
107.   <DynamicParameter>
108.     <DDD>30</DDD> 
109.   </DynamicParameter>
110.   <DynamicParameter>
111.     <ABC>2</ABC> 
112.   </DynamicParameter>
113. </DynamicVariables>
