TimeSpan.Parse Method (String, IFormatProvider)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Converts the string representation of a time interval to its TimeSpan equivalent by using the specified culture-specific format information.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Shared Function Parse ( _
    input As String, _
    formatProvider As IFormatProvider _
) As TimeSpan

public static TimeSpan Parse(
    string input,
    IFormatProvider formatProvider
)

Parameters

input
Type: System.String
A string that specifies the time interval to convert.

formatProvider
Type: System.IFormatProvider
An object that supplies culture-specific formatting information.

Return Value

Type: System.TimeSpan
A time interval that corresponds to input, as specified by formatProvider.

Exceptions

Exception	Condition
ArgumentNullException	input is nulla null reference (Nothing in Visual Basic).
FormatException	input has an invalid format.
OverflowException	input 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 in input is outside its valid range.

ArgumentNullException

input is nulla null reference (Nothing in Visual Basic).

FormatException

input has an invalid format.

OverflowException

input 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 in input is outside its valid range.

Remarks

The input 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 default value is a period (".") character.
hh	Hours, ranging from 0 to 23.
:	The culture-sensitive time separator symbol.
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 default value is a period (".") character.
ff	Optional fractional seconds, consisting of one to seven decimal digits.

The components of input 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 first tries to parse input by using the invariant format. If this is not successful, it then tries each of the culture-specific formats for the culture specified by formatProvider.

The formatProvider parameter is an IFormatProvider implementation that provides culture-specific information about the format of the returned string. The formatProvider parameter can be any of the following:

A CultureInfo object that represents the culture whose formatting conventions are to be reflected in the returned string. The DateTimeFormatInfo object returned by the CultureInfo.DateTimeFormat property defines the formatting of the returned string.
A DateTimeFormatInfo object that defines the formatting of the returned string.
A custom object that implements the IFormatProvider interface. Its IFormatProvider.GetFormat method returns a DateTimeFormatInfo object that provides formatting information.

If formatProvider is nulla null reference (Nothing in Visual Basic), the DateTimeFormatInfo object that is associated with the current culture is used.
