Property Value

Type: System.GlobalizationCultureInfo
An object that represents the current culture.
Exceptions
ExceptionCondition
ArgumentNullException

The property is set to .

ArgumentException

The property is set to a culture name that cannot be used to locate a resource file. Resource filenames must include only letters, numbers, hyphens or underscores.

Remarks

The UI culture specifies the resources an application needs to support user input and output, and by default is the same as the operating system culture. See the CultureInfo class to learn about culture names and identifiers, the differences between invariant, neutral, and specific cultures, and the way culture information affects threads and application domains. See the CultureInfoCurrentUICulture property to learn how a thread's default UI culture is determined.

The CultureInfo returned by this property can be a neutral culture. Neutral cultures should not be used with formatting methods such as StringFormat(IFormatProvider, String, Object), DateTimeToString(String, IFormatProvider), and ConvertToString(Char, IFormatProvider). Use the CultureInfoCreateSpecificCulture method to get a specific culture, or use the CurrentCulture property.

NoteNote

The CultureInfoCreateSpecificCulture method throws ArgumentException for the neutral cultures "zh-Hant" ("zh-CHT") and "zh-Hans" ("zh-CHS").

Examples

The following code example shows the threading statement that allows the user interface of a Windows Forms to display in the culture that is set in Control Panel. Additional code is needed.
