C# Get the code for the start and end time of a certain day

private static void start time of a day (DateTime which day, out DateTime start time, out DateTime deadline)
{
var Date = which day.Date;
Start time =(("yyyy-MM-dd 00:00:00"));
Deadline =(("yyyy-MM-dd 23:59:59"));
}
This is how it can be used when using it

Copy the codeThe code is as follows:

 
public static List<string> Get a word for a certain day (Which day is DateTime)
{ 
DateTime start time;
DateTime Deadline;
The starting deadline for a certain day (which day, out starting time, out deadline);
return Get non-repetitive phrases (start time, deadline);
} 

Not used to obtain non-repetitive phrases (DateTime which day) is considered to be more accurate in terms of the possibility of obtaining the phrases for the afternoon or a certain period of time!
