格式化DateTime.Now

Question

A peculiar request this one.

I am looking to compare two times in C#.

I have:

DateTime systemDate = DateTime.Now.AddMinutes(-15);
//which I presume subtracts 15 minutes from the current time

I am then reading in an ftp file from a Fedora server containing a date and time that I am reading in as a stream and converting to a DateTime

2011-03-17 09:00:18.000000000 +0000

I then parse this:

compareDate = DateTime.Parse(streamer);

My Question therefore is how do I format systemDate to be in the same format as the one I have parsed in compareDate? I am aware you can format DateTime but all of the sites I have seen so far dont have it in this format.

Thank you in advance, feel free to comment if you think I have missed anything :)

Answer 1

你可以这样

DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss");

Answer 2

No need to format systemDate , because you already parsed the date from the FTP server into a DateTime . You can just compare systemDate with compareDate .

Answer 3

just use var systemDate = DateTime.UtcNow.AddMinutes(-15); for your original one, then you just

if (DateTime.Equals(systemDate, compareDate))
{
    //...
}
