这位仁兄，建议你不要使用Console.ReadLine()这个方法组，其值为string，不能直接和您那枚举类型直接进行逻辑运算。建议你干脆不要使用ReadLine()了。using System; namespace ConsoleApplication2 {     [Flags]     public enum Weekday : uint //不必要的枚举 System.DayOfWeek 已经包含了周一至周六     {         Sunday, Monday, Tuesday,         Wednesday, Thursday, Friday, Saturday //定义数值     }     public class GetWeekdayNumber     {         public string Output = null;         public void GetNum(Weekday weekday)         {             Output = weekday.ToString();//输出         }     }     class Program     {         static void Main(string[] args)         {             GetWeekdayNumber getweekday = new GetWeekdayNumber();//实例化对象             getweekday.GetNum(Weekday.Sunday);//随意调控星期几             string str = string.Format("Today is {0}.", getweekday.Output);//输出语句             Console.WriteLine(str);         }     } }这段代码可以简化成：class p{     static void Main(){         System.Console.Write(System.DayOfWeek.Friday);     } }

你这里就没有用到判定啊，你只是在switch中判断了I的值然后输出对应的枚举值啊
