Question

If you could please assist me with this C# assignment. Screenshots would be greatly appreciated! Create a Windows application using C# visual studio that functions like a banking account register. The graphical user interface should initially allow the user to input the account name, number, and initial balance. Ensure that the full name is entered for the customer and that only numeric values are entered for number fields when the Create Account button is selected. Separate the business logic from the presentation layer by creating a Customer class. Include a deposit to and withdraw from methods in the Customer class to keep the balance updated. After an object of the Customer class is instantiated, provide textbox objects on your GUI for withdrawals and deposits. A second button should be available to update the account for withdrawal and deposit transactions showing the new balance. Can you please show the design code for the form?

Customer.cs

using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace BankApplication
{
class Customer
{
  
public string custname;
public int accNo;
public double balance;

public Customer(string name, int acc, double bal)
{
custname = name;
accNo = acc;
balance = bal;
}

public void deposit(double amount)
{
balance = balance + amount;
}

public void withdraw(double amount)
{
balance = balance - amount;
}

public double showBalance()
{
return balance;
}
  
}
}
