我有自己的DaysOfWeek标志枚举（有点）

我需要把每周的标准日和我的进行比较。我该怎么做呢？

由于枚举使用的天数顺序与内置的

DayOfWeek

相同，所以只需使用

DayOfWeek

类型的变量作为

的指数，然后将其与枚举变量按位并用即可

类似这样的内容（这将检查枚举的

Monday

标志是否为

）：

MyDayOfWeek Days=MyDayOfWeek.周一| MyDayOfWeek.周五；
DayOfWeek D=星期一的DayOfWeek；
var Mask=1由于枚举使用的天数顺序与内置的DayOfWeek
相同，因此只需使用DayOfWeek
类型的变量作为2
的指数，然后将其与枚举变量按位并用即可
类似这样的内容（这将检查枚举的Monday
标志是否为1
）：
MyDayOfWeek Days=MyDayOfWeek.周一| MyDayOfWeek.周五；
DayOfWeek D=星期一的DayOfWeek；
var Mask=1感谢大家的帮助。
最后，我有了解决办法
带旗帜的Own DaysOfWeek：
[Flags]
public enum DaysOfWeek
{
    None = 0,
    Sunday = 1 << 0,
    Monday = 1 << 1,
    Tuesday = 1 << 2,
    Wednesday = 1 << 3,
    Thursday = 1 << 4,
    Friday = 1 << 5,
    Saturday = 1 << 6,
}

如果您像这样更改枚举：
[Flags]
public enum DayOfWeek
{
    Sunday = 0,
    Monday = 1,
    Tuesday = 2,
    Wednesday = 3,
    Thursday = 4,
    Friday = 5,
    Saturday = 6
}

您可以尝试以下方法：
class Program
{
    public static bool Equal(DayOfWeek mine, System.DayOfWeek cSharp)
    {
        int mineInt = (int)mine;
        int cSharpInt = (int)cSharp;
        return mineInt == cSharpInt;
    }

    static void Main(string[] args)
    {

        DateTime dateTime = DateTime.Now;
        DayOfWeek dayOfWeek = DayOfWeek.Sunday;

        bool areEqual = Equal(dayOfWeek, dateTime.DayOfWeek);
        Console.WriteLine(areEqual);
        Console.ReadKey();
    }
}

class Program
{
    public static bool Equal(DayOfWeek mine, System.DayOfWeek cSharp)
    {
        if (mine == DayOfWeek.Friday && cSharp == System.DayOfWeek.Friday       || 
            mine == DayOfWeek.Monday && cSharp == System.DayOfWeek.Monday       || 
            mine == DayOfWeek.Saturday && cSharp == System.DayOfWeek.Saturday   || 
            mine == DayOfWeek.Sunday && cSharp == System.DayOfWeek.Sunday       || 
            mine == DayOfWeek.Thursday && cSharp == System.DayOfWeek.Thursday   ||
            mine == DayOfWeek.Tuesday && cSharp == System.DayOfWeek.Tuesday     || 
            mine == DayOfWeek.Wednesday && cSharp == System.DayOfWeek.Wednesday)
            return true;

        return false;
    }

    static void Main(string[] args)
    {

        DateTime dateTime = DateTime.Now;
        DayOfWeek dayOfWeek = DayOfWeek.Tuesday;

        bool areEqual = Equal(dayOfWeek, dateTime.DayOfWeek);
        Console.WriteLine(areEqual);
        Console.ReadKey();
    }
}

如果无法更改枚举，可以尝试以下操作：
class Program
{
    public static bool Equal(DayOfWeek mine, System.DayOfWeek cSharp)
    {
        int mineInt = (int)mine;
        int cSharpInt = (int)cSharp;

    }

    static void Main(string[] args)
    {

        DateTime dateTime = DateTime.Now;
        DayOfWeek dayOfWeek = DayOfWeek.Sunday;

        bool areEqual = Equal(dayOfWeek, dateTime.DayOfWeek);
        Console.WriteLine(areEqual);
        Console.ReadKey();
    }
}

class Program
{
    public static bool Equal(DayOfWeek mine, System.DayOfWeek cSharp)
    {
        if (mine == DayOfWeek.Friday && cSharp == System.DayOfWeek.Friday       || 
            mine == DayOfWeek.Monday && cSharp == System.DayOfWeek.Monday       || 
            mine == DayOfWeek.Saturday && cSharp == System.DayOfWeek.Saturday   || 
            mine == DayOfWeek.Sunday && cSharp == System.DayOfWeek.Sunday       || 
            mine == DayOfWeek.Thursday && cSharp == System.DayOfWeek.Thursday   ||
            mine == DayOfWeek.Tuesday && cSharp == System.DayOfWeek.Tuesday     || 
            mine == DayOfWeek.Wednesday && cSharp == System.DayOfWeek.Wednesday)
            return true;

        return false;
    }

    static void Main(string[] args)
    {

        DateTime dateTime = DateTime.Now;
        DayOfWeek dayOfWeek = DayOfWeek.Tuesday;

        bool areEqual = Equal(dayOfWeek, dateTime.DayOfWeek);
        Console.WriteLine(areEqual);
        Console.ReadKey();
    }
}

如果按以下方式更改枚举：
[Flags]
public enum DayOfWeek
{
    Sunday = 0,
    Monday = 1,
    Tuesday = 2,
    Wednesday = 3,
    Thursday = 4,
