TimeSpan.Parse Method (System) | Microsoft Learn

Source:: TimeSpan.cs

Source:: TimeSpan.cs

Source:: TimeSpan.cs

Source:: TimeSpan.cs

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

public:
 static TimeSpan Parse(System::String ^ input, IFormatProvider ^ formatProvider);

public:
 static TimeSpan Parse(System::String ^ input, IFormatProvider ^ formatProvider) = IParsable<TimeSpan>::Parse;

public static TimeSpan Parse(string input, IFormatProvider formatProvider);

public static TimeSpan Parse(string input, IFormatProvider? formatProvider);

static member Parse : string * IFormatProvider -> TimeSpan

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

Parameters

input: String

A string that specifies the time interval to convert.

formatProvider: IFormatProvider

An object that supplies culture-specific formatting information.

Returns

A time interval that corresponds to input, as specified by formatProvider.

Implements Exceptions

input has an invalid format.

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.

Examples

The following example defines an array of CultureInfo objects, and uses each object in calls to the Parse(String, IFormatProvider) method to parse the elements in a string array. The example illustrates how the conventions of a specific culture influence the formatting operation.

using System.Globalization;

Remarks

This method tries to parse input by using 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 null, the DateTimeFormatInfo object that is associated with the current culture is used.
