XMLSerialize Exception

Question

I am serializing a class and I get the following exception:

You must implement a default accessor on System.Configuration.SettingsPropertyCollection b

Answer 1

you have to have a default constructor, that is, one that does not take any parameters, like so....

class foo
{
    public foo() {}
}

if the class you are trying to serialize does not have one, XMLSerializer throws that exception. If you are trying to serialize a built-in class, you are going to have to derive your own or create a wrapper class.
