Parameters
- input
Type: System.String
A string that specifies the time interval to convert.
- formats
Type: array<System.String[]
A array of standard or custom format strings that defines the required format of input.

| Exception | Condition |
|---|---|
| ArgumentNullException | input is nulla null reference (Nothing in Visual Basic). |

Remarks
The ParseExact(String, String, IFormatProvider) method parses the string representation of a time interval, which must be in one of the formats defined by the formats parameter, except that leading and trailing white-space characters are ignored.
The formats parameter is a string array whose elements consist of 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. input must correspond exactly to a member of formats for the parse operation to succeed.
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.
