3.练习
为Ch10CardLib库编写⼀个控制台客户程序，从洗牌后的Deck对象中⼀次取出 5 张牌。如果这 5 张牌都是相同花⾊，客户程序就应在屏幕上显⽰这 5 张牌，以及⽂本 "Flush!"，否则在取出 50 张牌以后就输出⽂本 “No flush”，并退出。

//Remove()是按照内容移除
List<int> listRemove = new List<int>();
/
/添加两个数据5和15
listRemove.Add(5);
listRemove.Add(15);
listRemove.Remove(0); //没实际效果，因为listRemove中没有0
Console.WriteLine("listRemove[0] = " + listRemove[0]);
Console.WriteLine("listRemove[1] = " + listRemove[1]);
listRemove.Remove(5);
Console.WriteLine("listRemove.Remove(5)后,listRemove[0] = " + listRemove[0]);
//RemoveAt()是按照index移除
List<int> listRemoveAt = new List<int>();
//添加两个数据5和15
listRemoveAt.Add(2);
listRemoveAt.Add(12);
//listRemoveAt.RemoveAt(2); // 报错，因为超出范围
Console.WriteLine("listRemoveAt[0] = " + listRemoveAt[0]);

此外这篇博⽂⾥写的很详细，在使⽤后要注意长度和内容会改变
拙见如图：
可以理解为把这个⼩⽅格直接biu掉（误|||），全都往前移
