TimeSpan::ParseExact Method (String^, String^, IFormatProvider^)

 

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

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

public:
static TimeSpan ParseExact(
	String^ input,
	String^ format,
	IFormatProvider^ formatProvider
)

Parameters

input
Type: System::String^

A string that specifies the time interval to convert.

format
Type: System::String^

A standard or custom format string that defines the required format of input.

formatProvider
Type: System::IFormatProvider^

An object that provides culture-specific formatting information.

Return Value

Type: System::TimeSpan

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

Exception Condition
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 ParseExact(String^, String^, IFormatProvider^) method parses the string representation of a time interval, which must be in the format defined by the format parameter, except that leading and trailing white-space characters are ignored. Because input must conform to the format of format exactly, you should always use exception handling when converting a string input by the user to a time interval. If you prefer not to use exception handling, you can call the TryParseExact(String^, String^, IFormatProvider^, TimeSpan%) method instead.

The format parameter is a string that contains either a single standard format specifier, or one or more custom format specifiers that define the required format of input. For more information about valid format strings, see Standard TimeSpan Format Strings and Custom TimeSpan Format Strings.

System_CAPS_importantImportant

The ParseExact method uses the conventions of the culture specified by the formatProvider parameter only if format is a standard TimeSpan format string whose value is either "g" or "G". The "c", "t", and "T" standard format strings use the formatting conventions of the invariant culture. Custom format strings define the precise format of the input string and use literal characters to separate the components of a time interval.

The formatProvider parameter is an IFormatProvider implementation that provides culture-specific information about the format of the returned string if format is a standard format 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.

The following example uses the ParseExact(String^, String^, IFormatProvider^) method to parse several string representations of time intervals using various format strings and cultures.
