我们的编码教授简介希望我们使用c＃中的数组创建一个二十一点游戏。我们无法将“点击卡”的值添加到我们的初始总计中。当我们尝试多次击中时，它所做的就是替换第一张“击中的牌”，并且只将新牌加到初始牌中。

答案 0 :(得分：1)
您似乎永远不会更新您的初始总变量：Total1作为while (Stand == false)循环的一部分。相反，您完全按照您的描述进行操作：仅将新卡值添加到初始值。
每次stand循环遍历时，您需要做的是不重新声明Total3变量。将其声明移到循环之外。例如：
int Total3 = Total1; // Intialise the running total with the inital value from the deal
while (Stand == false)
{
...
Total3 = Total3 + Value5; // Add value of the newly dealt card to the running total.
Console.WriteLine("Total: " + Total3);
...
}
我还强烈建议您更好地重命名变量，以提高代码的可读性。命名变量Total1，Total2等并不是一种好的做法，这使得调试诸如您现在遇到的问题变得更加困难。让您的变量名称实际描述它们的用途，例如：而不是Total3将其命名为runningTotal。
