Question

您好我正在尝试制作一个简单的猎枪游戏，其中用户与CPU以及选择镜头，屏蔽或重新加载，但在我的switch语句和我的if语句中，当我尝试使用UserOption时，它给了我错误

运营商==无法应用于ShotgunGame.Program.ShotgunOption和int类型的操作数。

我不知道如何解决这个问题。

任何指导都将不胜感激

//Declare Variables

          }
            while (UserOption != ShotgunOption.Shield || CPUOption != ShotgunOption.Shield);
        } while (QUIT == false || gameCount == 3);

继承我的ShotgunOption枚举方法

enum ShotgunOption
     {
         Shoot = 1,
         Reload = 2,
         Shield = 3,


     }

您需要使用显式转换，因为ShotgunOption是枚举。

if((int)CPUOption == 1)
{ 
     ...
}

您已使用以下代码将int转换为enum类型，因此应明确您需要采用反向过程将枚举类型与int进行比较

ShotgunOption CPUOption = (ShotgunOption)computer.Next(1, 3);
