Syntax
public sealed class LocalDateTimePattern : IPattern<LocalDateTime>Properties
BclRoundtrip
Gets an invariant local date/time pattern which is ISO-8601 compatible, providing up to 7 decimal places
of sub-second accuracy which are always present (including trailing zeroes). This is compatible with the
BCL round-trip formatting of System.DateTime values with a kind of "unspecified".
This corresponds to the text pattern "uuuu'-'MM'-'dd'T'HH':'mm':'ss'.'fffffff". It does not necessarily
round-trip all
LocalDateTime values as it will lose sub-tick information. Use
FullRoundtripWithoutCalendar

Declaration
public static LocalDateTimePattern BclRoundtrip { get; }Property Value
| Type | Description |
|---|---|
| LocalDateTimePattern | An invariant local date/time pattern which is ISO-8601 compatible, providing up to 7 decimal places of sub-second accuracy which are always present (including trailing zeroes). |
Remarks
This pattern corresponds to the 'o' and 'O' standard patterns.
ExtendedIso
Gets an invariant local date/time pattern which is ISO-8601 compatible, providing up to 9 decimal places
of sub-second accuracy. (These digits are omitted when unnecessary.)
This corresponds to the text pattern "uuuu'-'MM'-'dd'T'HH':'mm':'ss;FFFFFFFFF".
Since 1.4.x
Availability netstandard2.0
Declaration
public static LocalDateTimePattern ExtendedIso { get; }Property Value
| Type | Description |
|---|---|
| LocalDateTimePattern | An invariant local date/time pattern which is ISO-8601 compatible, providing up to 9 decimal places of sub-second accuracy. |
Remarks
This pattern corresponds to the 'S' standard pattern ("longer sortable").
FullRoundtrip
Gets an invariant local date/time pattern which round trips values including the calendar system.
This corresponds to the text pattern "uuuu'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffff '('c')'".
Since 1.4.x
Availability netstandard2.0
Declaration
public static LocalDateTimePattern FullRoundtrip { get; }Property Value
| Type | Description |
|---|---|
| LocalDateTimePattern | An invariant local date/time pattern which round trips values including the calendar system. |
Remarks
This pattern corresponds to the 'R' standard pattern.
FullRoundtripWithoutCalendar
Gets an invariant local date/time pattern which round trips values, but doesn't include the calendar system.
It provides up to 9 decimal places of sub-second accuracy which are always present (including trailing zeroes).
This corresponds to the text pattern "uuuu'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffff". It will
round-trip all LocalDateTime values if the calendar system of the template value is the same
as the calendar system of the original value.

Remarks
See the user guide for the available pattern text options.

Create(String, CultureInfo, LocalDateTime)
Creates a pattern for the given pattern text, culture, and template value.

See the user guide for the available pattern text options. Note that the current culture
is captured at the time this method is called - it is not captured at the point of parsing

Availability netstandard2.0
Declaration
public string Format(LocalDateTime value)Parameters
| Type | Name | Description |

Parse(String)
Parses the given text value according to the rules of this pattern.

| String | text | The text value to parse. |
Returns
| Type | Description |
|---|---|
| ParseResult<LocalDateTime> | The result of parsing, which may be successful or unsuccessful. |
Remarks
This method never throws an exception (barring a bug in Noda Time itself). Even errors such as
the argument being null are wrapped in a parse result.
WithCalendar(CalendarSystem)
Creates a pattern like this one, but with the template value modified to use
the specified calendar system.
Since 2.0.x
Availability netstandard2.0
Declaration
public LocalDateTimePattern WithCalendar(CalendarSystem calendar)Parameters
| Type | Name | Description |
|---|---|---|
| CalendarSystem | calendar | The calendar system to convert the template value into. |
Returns
| Type | Description |
|---|---|
| LocalDateTimePattern | A new pattern with a template value in the specified calendar system. |
Remarks
Care should be taken in two (relatively rare) scenarios. Although the default template value is supported by all Noda Time calendar systems, if a pattern is created with a different template value and then this method is called with a calendar system which doesn't support that date, an exception will be thrown. Additionally, if the pattern only specifies some date fields, it's possible that the new template value will not be suitable for all values.
