Record logs (log processing), record log processing

1. Call methods:

By classifying logs, you can quickly locate errors and quickly solve problems in the project, which greatly improves efficiency and facilitates the overall work.

• TimeSpan comprehension:

Private string DateDiff (DateTime DateTime1, DateTime DateTime2)
{String dateDiff = null;
TimeSpan ts = DateTime1.Subtract (DateTime2 ). duration (); dateDiff = ts. days. toString () + "day" + ts. hours. toString () + "Hour" + ts. minutes. toString () + "Minute" + ts. seconds. toString () + "seconds ";
Return dateDiff;
}

(1) The DateTime Value Type represents a specific date time between 00:00:00 on January 1, January 1, 0001 AD and on January 1, December 31, 9999 AD. Therefore, you can use the DateTime value type to describe any time within the expected range.

A DateTime value represents a specific time;

(2) The TimeSpan value contains many attributes and methods for accessing or processing a TimeSpan value.

The following list covers some of them:

Add: Add to another TimeSpan value; Days: return the TimeSpan value calculated by the number of Days. Duration: obtains the absolute value of TimeSpan;

Hours: returns the TimeSpan value calculated in Hours; Milliseconds: returns the TimeSpan value calculated in Milliseconds; Minutes: returns the TimeSpan value calculated in Minutes;

Negate: returns the opposite number of the current instance; Seconds: returns the TimeSpan value calculated in Seconds; Subtract: minus another TimeSpan value;

Ticks: the number of tick returned for the TimeSpan value; TotalDays: the number of days indicated by the TimeSpan value; TotalHours: the number of hours represented by the TimeSpan value;

TotalMilliseconds: returns the number of milliseconds in the TimeSpan value. TotalMinutes: returns the number of minutes in the TimeSpan value. TotalSeconds: returns the number of seconds in the TimeSpan value;
