序列化运行时创建的类型

我在MSDN doc后面创建了一个System.Reflection.Emit类型

我用下面的代码创建了我的类型和实例:

//following the tutorial I created a method which returns a dynamic type
Type myDynamicType = CreateNewObject("MyDynamicType", fields);
var instance = Activator.CreateInstance(myDynamicType);

现在我想用XmlSerializer序列化我的对象

try this:

FileStream fs = new FileStream(@"C:'Test'SerializedDynamic.XML", FileMode.Create);            
XmlSerializer xs = new XmlSerializer(typeof(object));
xs.Serialize(fs, instance);

但是会抛出异常:

"The type MyDynamicType was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically."

有什么帮助吗

XmlSerializer xs = new XmlSerializer(myDynamicType);
XmlSerializer xs = new XmlSerializer(instance.GetType());
