Public Shared Function ParseExact (s As String, format As String) As DateOnly

Parameters

s

String

A string containing the characters that represent a date to convert.

format

String

A string that represent a format specifier that defines the required format of s.

Returns

DateOnly

An object that is equivalent to the date contained in s, as specified by format.

Exceptions

ArgumentNullException

s is null.

FormatException

s does not contain a valid string representation of a date.

Remarks

The ParseExact(String, String) method parses the string representation of a date, which must be in the format defined by the format parameter. It also requires that the <Date> element of the string representation of a date appear in the order specified by format, and that s have no white space other than that permitted by format. 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 s. For details about valid formatting codes, see Standard Date and Time Format Strings or Custom Date and Time Format Strings.

Note

If format is a custom format pattern that does not include date separators (such as "yyyyMMdd"), use the widest form of each custom format specifier. For example, if you want to specify months in the format pattern, specify the wider form, "MM", instead of the narrower form, "M".
