c#分配一个引用

我对

class

的

Lab

有一个问题，问题是我不确定如何分配我的参考

这是我的代码：

class Bank
{
    static List<Account> accounts = new List<Account>();
    static Account active_account; // this will be an active 
    // Account (reference) retrieved from 
    // the bank. This will need to initialised either by 
    // CreateAccount or by RetrieveAccount.

    static void Main()
    {
        bool running = true, valid_option = false;
        int user_option = 0, account_num = 0, account_pin = 0;
        string name = "", type = "";
        decimal balance = 0, credit = 0;
        Bank chosen = new Bank();

        Console.Write("account number:");
                    account_num = SafeReadInteger(0);
                    Console.Write("pin number:");
                    account_pin = SafeReadInteger(0);
                    Console.Write("Client name:");
                    name = Console.ReadLine();
                    Console.Write("Balance:");
                    balance = SafeReadDecimal(0);
                    Console.Write("type:");
                    type = Console.ReadLine();
                    Console.Write("Credit:");
                    credit = SafeReadDecimal(0);
        chosen.CreateAccount(account_num, account_pin, name, balance, type);
    }
}

我的问题是，我在哪里初始化

活动\u帐户

以及将其分配给什么？

您的CreateAccount方法不是构造函数。这是一种工厂方法。它的工作原理如下：

active_account = chosen.CreateAccount(
    account_num, account_pin, name, balance, type);

active_account.DoStuff();

---

您的银行实例有一个名为CreateAccount的工厂方法，该方法返回Account类的初始化实例

查看提供的代码，active_account用于保存刚刚创建的当前活动帐户，或者当有人登录时

---

它正在您发布的CreateAccount（）函数中初始化。类似地，RetrieveAccount（）函数将调用数据库并将活动帐户分配给新帐户对象

我发现用尾随下划线标记方法参数的风格令人信服。是你的发明还是讲师的口述。或者你有推荐它的造型引擎吗？

active_account = chosen.CreateAccount(
    account_num, account_pin, name, balance, type);

active_account.DoStuff();
