Change DateTimePicker Calendar Runtime
提问by Mohamad Draow
I want to view the calendar in another culture, for example let it show in Arabic. I use this code in the Main, but the calendar is still in the same culture:
我想查看另一种文化中的日历，例如让它以阿拉伯语显示。我在 Main 中使用此代码，但日历仍处于相同的文化中：
CultureInfo sa = new CultureInfo("ar-SA", false);
sa.DateTimeFormat.Calendar = new System.Globalization.HijriCalendar();
// Sets the culture to Arabic (Saudi Arabia)
Thread.CurrentThread.CurrentCulture = sa;
// Sets the UI culture to Arabic (Saudi Arabia)
Thread.CurrentThread.CurrentUICulture = sa;
I add the DateTimePicker on a form and expect that it shows the date in Arabic after running, but the DateTimePicker or Calendar is not changed to that culture.
我在表单上添加 DateTimePicker 并期望它在运行后以阿拉伯语显示日期，但 DateTimePicker 或 Calendar 不会更改为该文化。

The DateTimePicker and MonthCalendarcontrol do not reflect the CurrentUICulture property of an application's main execution thread when you created a localized application in the .NET Framework, in Visual Studio 2005, or in Visual Studio .NET
在 .NET Framework、Visual Studio 2005 或 Visual Studio .NET 中创建本地化应用程序时，DateTimePicker 和 MonthCalendar控件不反映应用程序主执行线程的 CurrentUICulture 属性

You can change the datepicker culture and format at runtime. For example the following changes the format to en-US:
您可以在运行时更改日期选择器文化和格式。例如，以下将格式更改为 en-US：
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US");
dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = Application.CurrentCulture.DateTimeFormat.ShortDatePattern;
On the other hand , use this to changes the culture and the date format of the datepicker to Saudi Arabia:
另一方面，使用它来将日期选择器的文化和日期格式更改为沙特阿拉伯：
Thread.CurrentThread.CurrentCulture = new CultureInfo("ar-SA");
System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("ar-SA");
dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = Application.CurrentCulture.DateTimeFormat.ShortDatePattern;

This changes the displayed format of the DateTimePicker - not date in the expanded view though.
这会更改 DateTimePicker 的显示格式 - 虽然不是展开视图中的日期。
CultureInfo ci = new CultureInfo("ar-SA");
DateTimeFormatInfo info = ci.DateTimeFormat;
dateTimePicker1.Format = System.Windows.Forms.DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = info.ShortDatePattern + " " + info.ShortTimePattern;
