C# Time Class using MySQL

  1 /*
  2  datatypes.
  3 
  4 Time class is writen in C# and .NET 2.0.
  5 
  6 Time class explantation.
  7 
  8 This is simple class and is not much to explain.
  9 
 10 1.Public fields: 
 11 .public int Hour, 
 12 .public int Minute and 
 13 .public int Second. 
 14 .public const char TIME_SEPERATOR = ‘:‘
 15 
 16 2.Constructors:
 17 .current system time (public Time()), 
 18 .from string value (public Time(string value)), 
 19 .from parameters (public Time(int hour, int minute, int second)) and 
 20 .from seconds (public Time(int seconds)).
 21 
 22 3.
 23 Public method Add:
 24 
 25 Example 1:
 26 
 27 InDoc.Systems.Time time1 = new InDoc.Systems.Time("12:00:55");
 28 // calculate 12:00:55 + 14:55:20 
 29 time1.Add("14:55:20");
 30 // result: 26:56:15
 31 
 32 4. To addition two times you can use + and to subtraction you can use -.
 33 Example 2:
 34 
 35 InDoc.Systems.Time time1 = new InDoc.Systems.Time("12:00:55") + 
 36 new InDoc.Systems.Time("14:55:20");
 37 // result: 26:56:15
 38 
 39 InDoc.Systems.Time time2 = new InDoc.Systems.Time("14:55:20") . 
 40 new InDoc.Systems.Time("12:00:55");
 41 // result: 02:54:25
 42 
 43 5. We have some convert methods:
 44 
 45 .public int ToSeconds(),
 46 .public override string ToString()
 47 
 48 and static method that convert secontd to Time object:
 49 .public static Time GetTimeFromSeconds(int seconds).
