[simple?] convert an unsigned long to byte array and vice versa

[Guest]

Is it possible to convert an unsigned long to byte array. For instance, unsigned long = 23480923

unsigned long longNumber;
longNumber=23480923; // in binary = 1 0110 0110 0100 1010 0101 1011
// so i want byteArray[0]=0000 0001 , byteArray[1]=0110 0110 ,
// byteArray[2]=0100 1010, byteArray[3]=0101 1011.

Is there a way to get the 4 bytes that make up this variable?
Also, is there a way to take a 4 byte array and convert it into a long?

TIA,

Is it possible to convert an unsigned long to byte array.

You can use BitConverter.GetBytes(ulong). However, that will use the
endianness of the platform, which may not be what you want.

Like BinaryWriter/BinaryReader, you can't specify the endianness. I
keep meaning to do something about that with utility classes...

(Use BitConverter.ToUInt64 for the reverse, btw.)
