xml序列化时怎么序列化Type类型的属性

xml序列化时如何序列化Type类型的属性
Hi,

我有一个类，此类有一个属性叫DataType，类型为Type，我想序列化这个类的实例，同样序列化DataType属性，比如输出成这样：
<MyObject>
  ...
  <DateType>System.Int32</DataType>
  ...
</MyObject>
但是会抛出异常（当前我要序列化的对象的DateType属性的值是typeof(int)），而像int，string等这些类型的属性都很正常，这要怎么解决呢？
抛出的异常是：InvalidOperationException
Message: Type System.Int32 may not be used in this context.

Thanks.

C# code

using System;using System.Data;using System.Data.SqlClient;using System.IO;using System.Text.RegularExpressions;using System.Xml.Serialization;namespace Demo{    public class MyObject    {        public string Name { get; set; }        public string Sex { get; set; }        [XmlIgnore]        public Type DataType { get; set; }        [XmlElement("DataType")]        public string DataTypeName        {            get { return DataType.ToString(); }            set { DataType = Type.GetType(value); }        }    }    internal class Program    {        private static void Main(string[] args)        {            MyObject obj = new MyObject() {Name = "jim", Sex = "Male", DataType = typeof (int)};            XmlSerializer serializer = new XmlSerializer(typeof (MyObject));            MemoryStream ms = new MemoryStream();            serializer.Serialize(ms, obj);            ms.Seek(0, SeekOrigin.Begin);            StreamReader sr = new StreamReader(ms);            string xml = sr.ReadToEnd();            Console.WriteLine(xml);            ms.Seek(0, SeekOrigin.Begin);            MyObject obj2 = serializer.Deserialize(ms) as MyObject;            Console.WriteLine(obj.DataType == obj2.DataType);            Console.WriteLine(obj.Name == obj2.Name);            Console.WriteLine(obj.Sex == obj2.Sex);            Console.ReadLine();        }    }}
