其实不用自己写Enum的位操作的，.net提供了

using System;

class FlagsAttributeDemo

{

// Define an Enum without FlagsAttribute.

enum SingleHue : short

{

Black = 0,

Red = 1,

Green = 2,

Blue = 4

};

// Define an Enum with FlagsAttribute.

[FlagsAttribute]

enum MultiHue : short

{

Black = 0,

Red = 1,

Green = 2,

Blue = 4

};

static void Main( )

{

Console.WriteLine(

"This example of the FlagsAttribute attribute \n" +

"generates the following output." );

Console.WriteLine(

"\nAll possible combinations of values of an \n" +

"Enum without FlagsAttribute:\n" );

// Display all possible combinations of values.

for( int val = 0; val <= 8; val++ )

Console.WriteLine( "{0,3} - {1}",

val, ( (SingleHue)val ).ToString( ) );

Console.WriteLine(

"\nAll possible combinations of values of an \n" +

"Enum with FlagsAttribute:\n" );

// Display all possible combinations of values.

// Also display an invalid value.

for( int val = 0; val <= 8; val++ )

Console.WriteLine( "{0,3} - {1}",

val, ( (MultiHue)val ).ToString( ) );

}

}

/*

最近看到有人自己写Enum的位操作来判读OR和AND的情况...

其次，我认为写SexEnum.男没有问题，毕竟这个产品不是用作多语言里的，都是中文的，枚举就用中文就ok了，不知道为啥会有人想不开，觉得这样写不好看...
