As the beginning of the week, I want to show you ‘working with Spans of Time’
Let’s jump into topic as usual;
Create and Initialize new TimeSpans
//Days.Hours:Minutes:Seconds:Miliseconds
TimeSpan myTimeSpan = TimeSpan.Parse("1.2:3:30.5");
DateTime myBirthday = DateTime.Parse("07/05/1997");
TimeSpan myAge = DateTime.Now.Subtract(myBirthday);
Get Individual Parts
myAge.Hours myAge.Seconds
…… or get TOTAL elapsed time as double representing both of number of days / hour / etc.
AND fractional values representing “left overs”
myTimeSpan.TotalDays // double myTimeSpan.TotalHours // double

Converts the string representation of a time interval to its TimeSpan equivalent.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
public static TimeSpan Parse( string s )
Parameters
- s
- Type: System.StringA string that specifies the time interval to convert.
Return Value
Type: System.TimeSpanA time interval that corresponds to s.
| Exception | Condition |
|---|---|
| ArgumentNullException |
s is null. |
| FormatException |
s has an invalid format. |
| OverflowException |
s represents a number that is less than TimeSpan.MinValue or greater than TimeSpan.MaxValue. -or- At least one of the days, hours, minutes, or seconds components is outside its valid range. |
The s parameter contains a time interval specification in the form:
[ws][-]{ d | [d.]hh:mm[:ss[.ff]] }[ws]
Elements in square brackets ([ and ]) are optional. One selection from the list of alternatives enclosed in braces ({ and }) and separated by vertical bars (|) is required. The following table describes each element.
| Element | Description |
|---|---|
| ws | Optional white space. |
| – | An optional minus sign, which indicates a negative TimeSpan. |
| d | Days, ranging from 0 to 10675199. |
| . | A culture-sensitive symbol that separates days from hours. The invariant format uses a period (“.”) character. |
| hh | Hours, ranging from 0 to 23. |
| : | The culture-sensitive time separator symbol. The invariant format uses a colon (“:”) character. |
| mm | Minutes, ranging from 0 to 59. |
| ss | Optional seconds, ranging from 0 to 59. |
| . | A culture-sensitive symbol that separates seconds from fractions of a second. The invariant format uses a period (“.”) character. |
| ff | Optional fractional seconds, consisting of one to seven decimal digits. |
The components of s must collectively specify a time interval that is greater than or equal to TimeSpan.MinValue and less than or equal to TimeSpan.MaxValue.
The Parse(String) method tries to parse s by using each of the culture-specific formats for the current culture.
