What will cause XML deserialize exception?
In MSDN, it says that xml deserialization is very forgiving if
a deserialized XML document doesn't closely match up with the object.
There is only a few error conditions lead to exceptions during the
deserialization process. The most common ones are:
- The name of the root element or its namespace did not match the expected name.
- An enumerated data type presented an undefined value.
- The document contained illegal XML.
My question
I want to know what else situations will cause xml deserialization exception?
My exploration
I figured out this might be true: if a value specified to an atomic element (the type of this element can't expand anymore), and the value can't implicitly convert from string to the type of the element (like int, double and etc), it will throw exception.
Example:
xml: <Class1><X1>Foo</X1></Class1>
class:
public class Class1 {
public int X1;
}
Because the value in xml is Foo, and it can't convert Foo to a int, so exception will be thrown. But xml deserialization will forgive that:
- Change the value
Footo10(any int value). - Change
public int X1topublic Class2 X1,Class2is a new class, XML will forgive it.
But these are all my guess :(
