The time that is short to almost zero is called instant, and instant represents the moment. The time interval can be regarded as a line segment, which must have a beginning and an end.
The time belongs to: the beginning of the second; The end of the second; At the end of the first few seconds; At the beginning of the next few seconds.
The time interval includes: the second; Seconds; The first few seconds; In the next few seconds; A few seconds to a few seconds.
The time interval refers to a period of time between two different instants Vector diameter Law Cartesian coordinate method And natural law to study the motion of a point to a reference system, including the motion equation, trajectory, velocity and acceleration of the point. The time interval generally corresponds to distance 、 displacement ,, etc Process quantity 。 The following is. net (C #) time difference Algorithm, with relevant instructions attached. ///
///Calculate the time interval between two dates///
1.DateTime Value Type It represents a specific date and time from 00:00:00, January 1, 0001 to 23:59:59, December 31, 9999. Therefore, you can use the DateTime value type to describe any time within the imagined range. A DateTime value represents a specific time 2. TimeSpan value contains many properties and methods, which are used to access or process a TimeSpan value
The following list covers some of them:
Add: Add with another TimeSpan value.
Days: returns the TimeSpan value calculated by days.
Duration: Get the absolute value of TimeSpan.
Hours: returns the TimeSpan value calculated in hours
Milliseconds: used for returning millisecond Calculated TimeSpan value. Minutes: used for returning minute Calculated TimeSpan value. Negate: returns the current instance's Inverse number 。 Seconds: used for returning second Calculated TimeSpan value. Subtract: Subtract another TimeSpan value from it.
Ticks: Returns the number of ticks of the TimeSpan value.
TotalDays: returns the number of days represented by the TimeSpan value.
TotalHours: returns the number of hours represented by the TimeSpan value.
TotalMilliseconds: Returns the number of milliseconds represented by the TimeSpan value.
