overrides ToString() of a POCO used by NHibernate

Question

how can I override ToStringmethod in a POCO object used as NHibernate model entity? To override object.ToString() you should declare something like

public override string ToString()
    {
        return "my string here";
    }

But NHibernate wants everything inside the POCO mapped objects to be virtual... and you can't declare a method both virtual ad override.

Any suggestion?

The fact that you are overriding the method means that it's virtual, there should be no problem.

true. I don't know what was going, but I had an NHibernate error message saying that the method must be declared virtual... now I tried again and the message disappered... probably there was something else wrong in my code – themarcuz Feb 03 '12 at 13:20

What is the reason to override ToString? Is it for debugging purposes? If so, while this doesn't actually answer your question, you could look at Debugger Attributes

My C# and NHibernate are both a bit rusty but I believe

public virtual string ToString()
{
    return "my string here";
}

is perfectly valid code.

The generated proxy should then use the provided implementation of ToString

this way you are shadowing Object.ToString(), not overriding it – themarcuz Feb 03 '12 at 13:16
