TimeSpan.ToString Method (String, IFormatProvider)

Converts the value of the current TimeSpan object to its equivalent string representation by using the specified format and culture-specific formatting information.

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

abstract ToString : 
        format:string * 
        formatProvider:IFormatProvider -> string  
override ToString : 
        format:string * 
        formatProvider:IFormatProvider -> string

Parameters

format
Type: System.String

A standard or custom TimeSpan format string.

formatProvider
Type: System.IFormatProvider

An object that supplies culture-specific formatting information.

Return Value

Type: System.String
The string representation of the current TimeSpan value, as specified by format and formatProvider.

Implements

IFormattable.ToString(String, IFormatProvider)

ExceptionCondition
FormatException

The format parameter is not recognized or is not supported.

The format parameter can be any valid standard or custom format specifier for TimeSpan values. If format is equal to String.Empty or is a null reference (Nothing in Visual Basic), the return value of the current TimeSpan object is formatted with the common format specifier ("c"). If format is any other value, the method throws a FormatException.

Important noteImportant

The custom format strings for TimeSpan values do not include a date or time separator. If you want to include these elements in your format string, you must treat them as character literals. See the example for an illustration, and see the Custom TimeSpan Format Strings topic for more information.

The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:

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 a null reference (Nothing in Visual Basic), the DateTimeFormatInfo object that is associated with the current culture is used. If format is a custom format string, the formatProvider parameter is ignored.

The following example calls the ToString(String, IFormatProvider) method to format two time intervals. The example calls the method twice for each format string, first to display it using the conventions of the en-US culture and then to display it using the conventions of the fr-FR culture.
