使用了网上盛传的SerializableDictionary
: Dictionary, IXmlSerializable 进行序列化Dictionary时，出现了序列化类型与对象实例类型不符的情况，不能序列化。
程序是这样的
public class TestObject { public TestObject() { } public TestObject(Dictionary dic) { this.dic = new SerializableDictionary(dic); } public SerializableDictionary dic; }
public abstract class A { public A() { } public A(int i) { this.i = i; } public int i; } public class B : A { public B() { } public B(int i) : base(i) { str = i.ToString(); } public string str; }
序列化TestObject对象程序：
Dictionary dic = new Dictionary(); dic.Add(new B(1), "1"); dic.Add(new B(2), "2"); dic.Add(new B(3), "3"); dic.Add(new B(4), "4"); TestObject obj = new TestObject(dic); // Serialize the object to a file. XmlTextWriter writer = new XmlTextWriter(@"c:\test.xml", null); XmlSerializer serializer = new XmlSerializer(typeof(TestObject)); serializer.Serialize(writer, obj);
结果，序列化类型与对象实例类型不符，序列化错误。
如何解决呢？用XmlInclude声明序列化类型，就可解决了。
在基类A上使用XmlInclude属性，代码如下：
[XmlInclude(typeof(B))] public abstract class A { public A() { } public A(int i) { this.i = i; } public int i; }
完成。希望对大家有帮助.
