我正在尝试编写实现STL库的德州扑克游戏。目前，我正在创建一个牌组，它是对象“卡片”的向量。我一直坚持使用random_shuffle（）算法来洗牌。我最终收到大量错误。我在安装了cygwin的NetBeans 8.2上编写此代码。（我必须这样做） 这是我得到的错误：
public string RoleId { get; set; }
public IdentityRole Role { get; set; }
我是编码的新手。有人能启发我这里做错了什么吗？任何帮助将不胜感激：）

该程序尚未完成，但是正如我对其进行的实际测试一样，我很确定shuffle算法存在问题，因为如果我不进行shuffle，它将成功运行。关于我拥有的数组，使用shuffle或random_shuffle算法的正确方法是什么？我是编码新手。任何帮助将不胜感激：）
答案 0 :(得分：0)
此：

?ThisFile
?totalLocation & Thisfile
应该是：
