Question

I want to refresh a page on a specific time.

From http-equiv="refresh" content="30" the page is refresh very 30 seconds,But I want page is refreshed on the specific time. like page is refresh on 1:30 of every day.

Answer 1

DateTime targetDate = ...;
long secondsTilRefresh = Math.Floor((targetDate - DateTime.Now).TotalSeconds);

Then, just use that value to fill the meta refresh tag. Of course, their browser may not remain open that long, and/or the browser may not support large values.
