Conflicting properties from interface and abstract class

[machinesofgod]

Hi,

I have a class that implements the ICollection interface and subclasses
the PropertyDescriptor class. The problem is that both the interface
and base class are expecting an implementation of the IsReadOnly
property. I have tried qualifying the property names with the interface
and base class name but it then complains that the modifiers 'override'
and 'public' are not valid for the property.

I've had a search around and I can only find topics discussing
conflicing method names rather than properties.

has anyone had a similar problem?

Regards,
Tom

ICollection doesn't include IsReadOnly, so I can't find a problem with a
name clash there.

However, if you need to implement the same property in an interface that
does include IsreadOnly, then you should do it like this :

class MyClass : PropertyDescriptor, IInterfaceThatIncludesIsReadOnly
{
public override bool IsReadOnly // PropertyDescriptor
{
...
}

bool IInterfaceThatIncludesIsReadOnly.IsReadOnly
{
...
}
}
