Question

I’m reading the date expires cookie (2 hours) from database, and I need to check if this date has passed. What’s the best way to do this?

For example:

public bool HasExpired(DateTime now)
{
    string expires = ReadDateFromDataBase(); // output example: 21/10/2011 21:31:00
    DateTime Expires = DateTime.Parse(expires);
    return HasPassed2hoursFrom(now, Expires);
}

I’m looking for ideas as write the .HasPassed2hoursFrom method.

Answer 1

public bool HasPassed2hoursFrom(DateTime fromDate, DateTime expireDate) 
{
    return expireDate - fromDate > TimeSpan.FromHours(2);
}
