 account.Deposit（SavingAccount.MonthlyInterestRate * account.Balance）; 
} 
 Console.WriteLine（  6个月后，{0}的帐户（＃ {1}），余额为：{2：C}，account.Owner，account.AccountNumber，account.Balance）; 
} 
 
} 
} 

我尝试过：



我试图在visual studio的另一个窗口中运行，但它显示全行代码的所有红线错误

解决方案

首先，C＃区分大小写，所以

 SavingAccount aSavingAccount; 

与<$不同的类p $ p>列表与LT; savingaccount> accounts = new List< savingaccount>（）;

由于它们是不同的类，后者不能包含前者的实例！另外，一个可能是错的，所以编译器可能会告诉你我找不到类XXX。



红线告诉有一个此代码存在问题 - 如果您查看错误窗格，它将为您提供问题所在的文本说明。 （双击错误消息，它将直接指向错误的行。）

What I have tried:

I tried to run in another window of visual studio but its showing all red line errors for full line code

解决方案

To start with, C# is case sensitive, so

SavingAccount aSavingAccount;

Is not the same class as

List<savingaccount> accounts = new List<savingaccount>();

And since they are different classes, the latter can';t contain instances of the former! Plus, one is probably wrong so the compiler is probably telling you "I can't find class XXX".

The "Red Lines" are telling "there is a problem with this code" - if you look at the Errors pane it will give you a text description of what the problem is. (Double click the error message, and it'll take you direct to the line in error.)
