In C #, convert the double type value to datetime.

In C #, datetime is the structure type, indicating the date and time between midnight on January 1, January 1, 0001 AD and 12:00:00 on January 1, December 31, 9999 AD.

A double value defined by time on a GPS device. Its start time is 1899-12-30 00:00:00.

The conversion method is as follows:

Datetime dt = new datetime (1899,12, 30); // start time

Double timenow = getgpstime (); // get the time from the device, double type (8 bytes ).

Dt = DT. adddays (timenow); // converts the value to the date type in C #. The integer part is converted to the number of days, and the fractional part is rounded to milliseconds.

Console. writeline ("now is:" + dt. tostring ());
