string to bitmask

[Just D]

All,

What's the easiest way to convert the string like 1001010101101010101 into a
binary mask of type Int64 and back? ConvertBitmask or something like that?

Just D.

I would probably just write a loop.

char [] chars = string.ToCharArray[]
for(int i=0;i<chars.Length;i++) {
yourvalue |= (chars - '0') << i;
}

or with unsafe code
int length = string.Length;
fixed(char *start = string) {
while(current < length) {
yourvalue |= (chars - '0') << current;
current++;
}
}

You could also use the BitVector32 class if you prefer to not deal with
shifting etc.
