这就是我想要实现的目标：
如果要求提取超过允许透支限额(100美元(的款项，则不会提取任何款项，并从余额中扣除固定的固定费用(10美元(。
在下面的代码中，我已经尽了最大努力，但它不起作用，因为当我提取超出余额的金额时，它不会给我失败的交易费，而是给我负余额。我也不确定当用户点击他们想要查看的账户详细信息时，如果用户透支了，我希望它显示失败的交易费用(如果有的话(。
任何帮助都将不胜感激。我就是想不通。

我已经对你的代码进行了重构——很难理解你想做什么——所以这是一个很大的变化。我已经删除了很多重复，但我不能真正完成所有内容，因为你的代码中也有很多缺失。
我无法回答如何在代码中修复你的一个方法，因为你在帐户类中更改状态的方式真的很难遵循。
在重构中，我总是这样计算Balance：
public decimal Balance => this.Opening + this.Deposits - this.Withdrawals + this.Interest - this.Fees;
所以现在只需要正确处理Balance的各个组件。
以下是Withdraw现在如何做到这一点：
public (decimal Withdrawn, decimal Fee) Withdraw(decimal amount)
{
if (amount <= 0m)
{
throw new System.InvalidOperationException("Withdrawal amount must be positive");
}
decimal fee = 0;
if (amount > this.Overdraft)
{
amount = 0m;
fee = 10m;
}
else if (this.Balance < amount)
{
amount = this.Balance;
}
this.Withdrawals -= amount;
return (amount, fee);
}
如果我理解正确的话，当你试图提取超过Overdraft金额的款项时，你会得到$10费用，但不会提取任何款项。我增加了一张支票，以确保您提取的金额不会超过余额。
以下是我重构的其余部分。让我知道你需要讨论什么：

Everyday everyday = new Everyday(client, Account.GenerateAccountNumber(), 30m);
Console.WriteLine($"Balance: {everyday.Balance}");
var r1 = everyday.Withdraw(15m);
Console.WriteLine($"Withdrawn: {r1.Withdrawn}, Fee: {r1.Fee}, Balance: {everyday.Balance}");
var r2 = everyday.Withdraw(1000m);
Console.WriteLine($"Withdrawn: {r2.Withdrawn}, Fee: {r2.Fee}, Balance: {everyday.Balance}");
var r3 = everyday.Withdraw(10m);
Console.WriteLine($"Withdrawn: {r3.Withdrawn}, Fee: {r3.Fee}, Balance: {everyday.Balance}");
}
这就给出了：
Balance: 30
Withdrawn: 15, Fee: 0, Balance: 15
Withdrawn: 0, Fee: 10, Balance: 5
Withdrawn: 5, Fee: 0, Balance: 0
