Question

I have this method:

public static int SetFlag(this int i, int flag, bool set = true)
{
     return (set) ? i | flag : ((i & flag) != 0) ? (i-flag) : i;

     if(
}

Just wondering how to read it. Is it saying there are 2 ternary condictions? Do I read it from right to left or left to right?

Answer 1

That code is equivalent to:

if (set)
    return i | flag;
else
    if ((i & flag) != 0)
        return i-flag;
    else
        return i;
