I'm reading elements from a XML file, and when i get to
anElement.Name = aReader.ReadElementString();

when i'm debugging i get the exception:

'EndElement' is an invalid nod type. Line 4, position 31.

and when i'm not debugging i get (just start without debugging):

'None' is an invalid node type. Line 98, position 16.

I hope someone has an answer why i get an exception and why they are
different

thanks

Well, with no any idea about your XML, code and full exception info
I doubt we can help you. Most likely you are using ReadElementString()
method in a wrong way.
And about the difference between debugging and not - XmlReader as
forward-only reader is a bit fragile WRT debugging, e.g. imagine
reader.ReadElementString() expression in Watch window - it can spoil
your processing by moving reader further.
