c# - using bitwise operation to extract month from int date (yyyyMMdd)

Question

Is it possible to extract the month from date represented as int (format YYYYMMDD, e.g. 20110401) using some bitwise operators?

If so, how can it be done?

edit: I am currently using 20110401 % 10000 / 100. I thought bit-wise could be faster. DateTime.Parse etc. are too slow for what I am trying to do.

Answer 1

No, because bitwise operators work with the binary representation of the number. Your date is encoded using a decimal representation.

You can do it using arithmetic operators though:

int date = 20110401;

int day = date % 100;
int month = (date / 100) % 100;
int year = date / 10000;
