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.
