C # get UTC time, and UTC datetime convert each other

Mostly from http://blog.sina.com.cn/s/blog_4c6e822d0102dsdz.html.

Just start learning a little C # knowledge and study the UTC time acquisition as follows

DateTime dt = Datetime.utcnow;

Other:

The DateTime.UtcNow.ToString () output is a 0 time zone event,

DateTime.Now.ToString () output is the time of the current time zone, we in China use the East eight district time, so the difference 8 hours

Here is the conversion of class to each other

class UTC

{

public static int Convertdatetimeint (System.DateTime time)

{

Double intresult = 0;

System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime (New System.DateTime (1970, 1, 1));

Intresult = (time-starttime). TotalSeconds;

return (int) intresult;

}

public static DateTime Convertintdatetime (double UTC)

{

System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime (New System.DateTime (1970, 1, 1));

StartTime = Starttime.addseconds (UTC);

StartTime = starttime.addhours (8);//Convert to Beijing time (Beijing time =UTC time + 8 hours)

return startTime;

}

Calling methods

DateTime UtcNow = DateTime.Now.ToUniversalTime ();

Double utc= Convertdatetimeint (UtcNow);

DateTime dtime = convertintdatetime (UTC);

}
