USING C# CODING LANGAUGE

Please use your solution from Exercise $6$ and implement Encapsulation in at least $5$ places $($property$,$ method$)$ within your code. Afterward, provide a report explaining why you chose to apply encapsulation to those specific places.

Exercise $6$: Bank and Bank Accounts

Create a set of classes that describe a bank and different types of bank accounts. The classes should include:

Checking Account

Savings Account

Add the following methods to each bank account:

CloseAccount: Used when a bank account must be closed.

AddFunds: Used when we need to add funds to the account.

CheckBalance: Used when we need to check the current balance of the account.

GetTransactionCount: Tracks the number of transactions on the account.

The bank must have the following properties and methods:

A property to keep track of all its members.

A balance property, which is affected by user transactions.

The following methods for the bank:
