How can I get object type?

[hrabia]

I have one base class. This class is used as parameter for method that serializes an object of that class to xml (using XmlSerializer).

class Base {.......}

class X
{
public void Serialize(Base obj)
{
XmlSerializer _o = new XmlSerializer(typeof(Base));
...................
}
}

I have second class that derives from base class.

class Second : Base {.......}

When I use object of second class as parameter for my method I need a type of my object for constructor of XmlSerializer(typeof(Second)).

Serialize(new Second());

But my method know only type of base class, and only XmlElemnts of base class are serialized. How can get this type dynamicaly?

Are you making sure to set the [Serializable()] attribute of both the base and the inherited class?

i.e.

[Serializable()]
public class Base {
  // etc
}

[Serializable()]
public class Second : Base {
  // etc
}

Hmm, I use only [XmlElement] for properties. It has worked fine until inheritance...

Instead of using typeof(Second), just call obj.GetType().

obj.GetType() - I got errors when I used this function. I think it shoud be overriden.

What sort of errors? GetType() should never cause any errors. And it cannot be overriden, because it is not virtual in Object.
