.NET中是否有内置类或某些东西可以将字节数组视为大位域?
Take a look at the BitArray class.
Here is an example explaining what is going on when using a byte array:
byte[] myBytes = new byte[5] { 1, 2, 3, 4, 5 };
BitArray myBA3 = new BitArray( myBytes );
Console.WriteLine( "myBA3" );
Console.WriteLine( " Count: {0}", myBA3.Count );
Console.WriteLine( " Length: {0}", myBA3.Length );
Console.WriteLine( " Values:" );
PrintValues( myBA3, 8 );
public static void PrintValues( IEnumerable myList, int myWidth )
{
int i = myWidth;
foreach ( Object obj in myList )
{
if ( i <= 0 )
{
i = myWidth;
Console.WriteLine();
}
i--;
Console.Write( "{0,8}", obj );
}
Console.WriteLine();
}
This code produces the following output.
myBA3
Count: 40
Length: 40
Values:
Bit0 Bit1 Bit2 Bit3 Bit4 Bit5 Bit6 Bit7
True False False False False False False False
Bit8 Bit9 Bit10 Bit11 Bit12 Bit13 Bit14 Bit15 ... and so on
False True False False False False False False
True True False False False False False False
False False True False False False False False
True False True False False False False False
