Anything wrong with using the left shift operator?

int x = y << z;
 
The shift operation replaces the shifted bits by 0
What I would like is that the shifted bit goes to the right of the byte

Any idea

Thank

Gilles

Ah, I see. Sorry! Well, you could do:

public static uint RotateLeft (uint original, int bits)
{
return (original << bits) | (original >> (32-bits));
}

Does that help?
