C# 简单控制台应用程序枚举问题

Question

我是 C# 新手，需要以下代码方面的帮助。

这个控制台应用程序应该在 5 个不同的对应数组中存储 5 个申请人的详细信息。最后，这应该允许我通过我在声明我的数组后创建的菜单来查看申请人的姓名。请注意，该计划尚未完成。

                    }
            }
        }
    }
}
}

我在第 78 行有一个错误说明：

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

任何人都可以提供任何建议以解决此问题。

谢谢。

Answer 1

loq[i] = (Qualifying)num;

应该是

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

loq 存储一个字符串类型，而您正尝试放入 Qualifying 的枚举。
