C＃中的PyEphem（日出/日落时间计算）等效项

Question

PyEphem is a neat library that allows easy calculation of sunrise, set, dawn, and dusk of location based on lat, long, and UTC timestamp

I don't want to go through the calculation myself, rather I was wondering if there is an existing library I could use

Answer 2

I know this post is old but check out CoordinateSharp . It can do exactly what you described. It can even do Solar/Lunar eclipse calculations.

Example Usage:

Coordinate c = new Coordinate(19.0991676, -98.2209974, DateTime.Now());
c.CelestialInfo.SunRise; //Returns sunrise nullable DateTime for location.
