TimeSpan.Parse Method (String, IFormatProvider)

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)

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.

ExceptionCondition
ArgumentNullException

input is null.

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.

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 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:

If formatProvider is null, the DateTimeFormatInfo object that is associated with the current culture is used.

Notes to Callers

When a time interval component in the string to be parsed contains more than seven digits, parsing operations in the .NET Framework 3.5 and earlier versions may behave differently from parsing operations in the .NET Framework 4. In some cases, parsing operations that succeed in the .NET Framework 3.5 and earlier versions may fail and throw an OverflowException in the .NET Framework 4. In other cases, parsing operations that throw a FormatException in the .NET Framework 3.5 and earlier versions may fail and throw an OverflowException in the .NET Framework 4. The following example illustrates both scenarios.

string[] values = { "000000006", "12.12:12:12.12345678" };
foreach (string value in values)
{
   try {
      TimeSpan interval = TimeSpan.Parse(value);
      Console.WriteLine("{0} --> {1}", value, interval);
   }   
   catch (FormatException) {
      Console.WriteLine("{0}: Bad Format", value);
   }   
   catch (OverflowException) {
      Console.WriteLine("{0}: Overflow", value);
   }
}
// Output from .NET Framework 3.5 and earlier versions: 
//       000000006 --> 6.00:00:00 
//       12.12:12:12.12345678: Bad Format       
// Output from .NET Framework 4: 
//       000000006: Overflow 
//       12.12:12:12.12345678: Overflow

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.

      string[] values = { "6", "6:12", "6:12:14", "6:12:14:45",

      CultureInfo[] cultures = { new CultureInfo("en-US"), 
                                 new CultureInfo("ru-RU"),
                                 CultureInfo.InvariantCulture };

      string header = String.Format("{0,-17}", "String");
      foreach (CultureInfo culture in cultures)
         header += culture.Equals(CultureInfo.InvariantCulture) ? 
                      String.Format("{0,20}", "Invariant") :
