I have created my own class called Transaction.
I have overloaded the Equals and NotEquals functions so that I can
simply use == or != to compare 'Transactions'.
The problem I am faced with is that I cannot figure out how to account
for Null transactions.
If inside the Equals function I say:
public override bool Equals(Object obj)
{
Transaction x = (Transaction) obj;
if (this == null || x == null)
return false; // will never reach here, because the
above will continue to loop forever until i get a stack overflow
because it will recursively call Equals a billion times.
// my normal comparison checks
}
If I try to look at a member variable to validate (x.AcquirerRT ==
null) i get an 'object not instantiated' error message. Which makes
sense.
I understand what is going on, but I don't know how to get around it.
Any time I try to say "== null", I get a stack overflow. So then how
can I check for null?
