While I don't know C# I doubt that this is good C# code ;)
Here's a moderately cleaned-up Python version:
class DuplicateCustomerError(Exception):
pass
class Customer:
def __init__(self, name):
self.name = name
class Bank:
def __init__(self):
self.customers = {}
def add_customer(self, name):
if name in self.customers:
raise DuplicateCustomerError
customer = Customer(name)
self.customers[name] = customer
return customer
if __name__ == "__main__":
bank = Bank()
bank.add_customer("XYZ")
I'm assuming a tiny bank where every customer has a unique name and only one
program is running so that you can ignore concurrency issues.
