【问题描述】：

我试图让此代码在显示最后一行后继续重复，并根据需要重复多次，然后在为帐号输入特定数字后显示终止消息。最好的方法是什么？我一直在努力尝试解决 if 语句，也许有人有解决方案。

public static void Main(string[] args)
{ //begin main
  int AccountNumber; //declare account number

  int BeginingBalance; //declare begining balance

  int TotalItemsCharged; //declare total items charged

  int TotalCreditsApplied; //declare total credits applied

  int CreditLimit; //declare credit limit

  Double Balance; //declare end balance

  {
     Console.Write("account number: "); // prompt user for account number
     AccountNumber = Convert.ToInt32(Console.ReadLine());

     Console.Write("begining balance: "); //prompt user for begining balance
     BeginingBalance = Convert.ToInt32(Console.ReadLine());

     Console.Write("total items charged: ");
     TotalItemsCharged = Convert.ToInt32(Console.ReadLine()); //prompt user for items charged

     Console.Write("total credits applied:");
     TotalCreditsApplied = Convert.ToInt32(Console.ReadLine()); //prompt user for credits applied

     Console.Write("credit limit:"); //prompt user for credit limit
     CreditLimit = Convert.ToInt32(Console.ReadLine());

     Balance = BeginingBalance + TotalItemsCharged - TotalCreditsApplied;

     Console.Write("balance is: {0}", Balance); //display calculated balance

     if (Balance > CreditLimit) //set if statement
        Console.WriteLine(" Credit Limit Exceeded"); //set display for true if statement

     Console.ReadLine();
      } // end main
   }
}

您熟悉while 循环吗？
请买一本好的C#书，这是一个非常基础的问题。

while (true) 怎么样？那肯定会重复... :)
我猜最里面的括号是你想要重复的，在几乎所有的编程中，这被称为循环。您应该能够在您最喜欢的搜索引擎上查找有关循环的大量资源

【解决方案1】：

// Keep asking for an account number until 0 is entered as account number
while ((AccountNumber = Convert.ToInt32(Console.ReadLine())) != 0)
{
    // No need to ask for the account number again, the while loop takes care
    // of that.

    // So...
    // do stuff, such as...
    BeginningBalance = Convert.ToInt32(Console.ReadLine());
    // and more stuff... etc...
}
