C#- Create an application that reads the contents of the file into an array or a List. The application should then let the user enter a charge account number. The program should determine whether the number is valid by searching for it in the array or List that contains the valid charge account numbers. If the number is in the array or List, the program should display a message indicating the number is valid. If the number is not in the array or List, the program should display a message indicating the number is invalid. The ChargeAccount.txt is below.
