Key Code:
1. Long and short Format
private
void
Display_Click(
object
sender, RoutedEventArgs e)
{
// We keep results in this variable
StringBuilder results =
new
StringBuilder();
// Create basic date/time formatters.
DateTimeFormatter[] basicFormatters =
new
[]
{
// Default date formatters
new
DateTimeFormatter(
"shortdate"
),
new
DateTimeFormatter(
"longdate"
),
// Default time formatters
new
DateTimeFormatter(
"shorttime"
),
new
DateTimeFormatter(
"longtime"
),
};
// Create date/time to format and display.
DateTime dateTime = DateTime.Now;
// Try to format and display date/time if calendar supports it.
foreach
(DateTimeFormatter formatter
in
basicFormatters)
{
// Format and display date/time.
results.AppendLine(formatter.Template +
": "
+ formatter.Format(dateTime));
}
}
|
2. Use different parameters.
private
void
Display_Click2(
object
sender, RoutedEventArgs e)
{
// This scenario uses the Windows.Globalization.DateTimeFormatting.DateTimeFormatter class
// to format a date/time by specifying a template via parameters.
// We keep results in this variable
StringBuilder results =
new
StringBuilder();
// Create formatters with individual format specifiers for date/time elements.
DateTimeFormatter[] templateFormatters =
new
[]
{
// Example formatters for dates.
new
DateTimeFormatter(
YearFormat.Full,
MonthFormat.Abbreviated,
DayFormat.Default,
DayOfWeekFormat.Abbreviated),
new
DateTimeFormatter(
YearFormat.Abbreviated,
MonthFormat.Abbreviated,
DayFormat.Default,
DayOfWeekFormat.None),
new
DateTimeFormatter(
YearFormat.Full,
MonthFormat.Full,
DayFormat.None,
DayOfWeekFormat.None),
new
DateTimeFormatter(
YearFormat.None,
MonthFormat.Full,
DayFormat.Default,
DayOfWeekFormat.None),
// Example formatters for times.
new
DateTimeFormatter(
HourFormat.Default,
MinuteFormat.Default,
SecondFormat.Default),
new
DateTimeFormatter(
HourFormat.Default,
MinuteFormat.Default,
SecondFormat.None),
new
DateTimeFormatter(
HourFormat.Default,
MinuteFormat.None,
SecondFormat.None),
};
// Create date/time to format and display.
DateTime dateTime = DateTime.Now;
// Try to format and display date/time if calendar supports it.
foreach
(DateTimeFormatter formatter
in
templateFormatters)
{
// Format and display date/time.
results.AppendLine(formatter.Template +
": "
+ formatter.Format(dateTime));
}
}
|
3. use String Template
private
void
Display_Click3(
object
sender, RoutedEventArgs e)
{
// We keep results in this variable
StringBuilder results =
new
StringBuilder();
// Create template-based date/time formatters.
DateTimeFormatter[] templateFormatters =
new
[]
{
// Formatters for dates.
new
DateTimeFormatter(
"day month"
),
new
DateTimeFormatter(
"month year"
),
new
DateTimeFormatter(
"day month year"
),
new
DateTimeFormatter(
"dayofweek day month year"
),
new
DateTimeFormatter(
"dayofweek.abbreviated"
),
new
DateTimeFormatter(
"month.abbreviated"
),
new
DateTimeFormatter(
"year.abbreviated"
),
// Formatters for time.
new
DateTimeFormatter(
"hour"
),
new
DateTimeFormatter(
"hour minute"
),
new
DateTimeFormatter(
"hour minute second"
),
};
// Create date/time to format and display.
DateTime dateTime = DateTime.Now;
// Try to format and display date/time if calendar supports it.
foreach
(DateTimeFormatter formatter
in
templateFormatters)
{
// Format and display date/time.
results.AppendLine(formatter.Template +
": "
+ formatter.Format(dateTime));
}
}
|
C++ code
1 Long and short format
void
App2::MainPage::Button_Click_1(Platform::Object^ sender, Windows::UI::Xaml::RoutedEventArgs^ e)
{
Array<DateTimeFormatter^> ^dateFormatters = {
ref
new
DateTimeFormatter(
"shortdate"
),
ref
new
DateTimeFormatter(
"longdate"
),
ref
new
DateTimeFormatter(
"longtime"
)
};
Windows::Globalization::Calendar^ cal =
ref
new
Windows::Globalization::Calendar();
Windows::Foundation::DateTime dateToFormat = cal->GetDateTime();
String^ results =
""
;
for
(unsigned
int
i = 0; i < dateFormatters->Length; i++)
{
results = results + dateFormatters[i]->Template +
": "
+ dateFormatters[i]->Format(dateToFormat) +
"\n"
;
}
}
|
2. Use different parameter
void
App2::MainPage::Button_Click_2(Platform::Object^ sender, Windows::UI::Xaml::RoutedEventArgs^ e)
{
Array<DateTimeFormatter^> ^dateFormatters = {
ref
new
DateTimeFormatter(
YearFormat::Full,
MonthFormat::Abbreviated,
DayFormat::Default,
DayOfWeekFormat::Abbreviated),
ref
new
DateTimeFormatter(
YearFormat::Abbreviated,
MonthFormat::Abbreviated,
DayFormat::Default,
DayOfWeekFormat::None),
ref
new
DateTimeFormatter(
YearFormat::Full,
MonthFormat::Full,
DayFormat::None,
DayOfWeekFormat::None),
ref
new
DateTimeFormatter(
YearFormat::None,
MonthFormat::Full,
DayFormat::Default,
DayOfWeekFormat::None),
ref
new
DateTimeFormatter(
HourFormat::Default,
MinuteFormat::Default,
SecondFormat::Default),
ref
new
DateTimeFormatter(
HourFormat::Default,
MinuteFormat::Default,
SecondFormat::None),
ref
new
DateTimeFormatter(
HourFormat::Default,
MinuteFormat::None,
SecondFormat::None)
};
// Obtain the date that will be formatted.
Windows::Globalization::Calendar^ cal =
ref
new
Windows::Globalization::Calendar();
Windows::Foundation::DateTime dateToFormat = cal->GetDateTime();
// Keep the results here
String^ results =
""
;
// Generate the results.
for
(unsigned
int
i = 0; i < dateFormatters->Length; i++)
{
// Perform the actual formatting.
results = results + dateFormatters[i]->Template +
": "
+ dateFormatters[i]->Format(dateToFormat) +
"\n"
;
}
}
|
3.Use String Template
void
App2::MainPage::Button_Click_3(Platform::Object^ sender, Windows::UI::Xaml::RoutedEventArgs^ e)
{
Array<DateTimeFormatter^> ^dateFormatters = {
ref
new
DateTimeFormatter(
"month day"
),
ref
new
DateTimeFormatter(
"month year"
),
ref
new
DateTimeFormatter(
"month day year"
),
ref
new
DateTimeFormatter(
"month day dayofweek year"
),
ref
new
DateTimeFormatter(
"dayofweek.abbreviated"
),
ref
new
DateTimeFormatter(
"month.abbreviated"
),
ref
new
DateTimeFormatter(
"year.abbreviated"
),
ref
new
DateTimeFormatter(
"hour minute"
),
ref
new
DateTimeFormatter(
"hour minute second"
),
ref
new
DateTimeFormatter(
"hour"
)
};
// Obtain the date that will be formatted.
Windows::Globalization::Calendar^ cal =
ref
new
Windows::Globalization::Calendar();
Windows::Foundation::DateTime dateToFormat = cal->GetDateTime();
// Keep the results here
String^ results =
""
;
// Generate the results.
for
(unsigned
int
i = 0; i < dateFormatters->Length; i++)
{
results = results + dateFormatters[i]->Template +
": "
+ dateFormatters[i]->Format(dateToFormat) +
"\n"
;
}
}
