C#简单控制台应用程序枚举问题

Question

我是C＃的新手，需要在以下代码中寻求帮助。

此控制台应用程序应该将5个申请人的详细信息存储在5个不同的相应数组中。最后，在声明数组后，这应该允许我通过我创建的菜单查看申请人的名称。请注意，该程序尚未完成。

                    }
            }
        }
    }
}
}

我在第78行遇到了一个错误，错误信息如下：

"无法将类型 'ConsoleApplication1.Qualifying' 隐式转换为 'string'"

请问有什么建议可以解决这个问题吗？

谢谢。

loq[i] = (Qualifying)num; - Joel Coehoorn

Answer 1

loq[i] = (Qualifying)num;

应该是

loq[i] = ((Qualifying)num).ToString();

loq 存储的是字符串类型，而你试图传入一个 Qualifying 枚举类型。
