Casting to inhering type from inherited type

[Jan Scamba]

try leppies solution bellow

So I can´t cast to a more advanced type, but casting to a less advanced is okay.

I think you need to study inheritance and polymorphism a bit more. It takes a while to get to understand it, but once you do, it all seems natural.

Thanks for your help, though u could work on your manners a bit.

My manners are irrelevant. I do not like to spoon-feed people.

His responses appeared to be quite polite. Curt, for sure, but polite.

Why was the message deleted? Because the OP said the proposed solution didn't work? That's not a very good reason as now no one else who runs into the same (or similar) problem will know not to try that approach.

Yes you´re quite right. My apologies Leppie.

in general these kinds of casts will only work towards the base class. ie a test is an XmlDocument but an XmlDocument is Not necessarily a test. you could use the "as" operator t = doc as test; this will return t == null if doc is not of type test. If you know how to convert an XmlDocument into a test then you could create a cast for it public static explicit operator Test(XmlDocument doc) { //your conversion algorithm here } HTH Russ
