      Balance = initialBalance; // Balance's set accessor validates
   }
   public decimal Balance
   {
      get
      {
         return balance;
      }
      private set // can be used only within the class
      {
         if (value > 0.0m) // m indicates that 0.0 is a decimal literal
         {
            balance = value;
         }
      }
   }
   public void Deposit(decimal depositAmount)
   {
      if (depositAmount > 0.0m) // if the depositAmount is valid
