TextInfo Class

Defines properties and behaviors, such as casing, that are specific to a writing system.

Namespace: System.Globalization
Assembly: mscorlib (in mscorlib.dll)

public class TextInfo : ICloneable, IDeserializationCallback
/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
public class TextInfo implements ICloneable, IDeserializationCallback
public class TextInfo implements ICloneable, IDeserializationCallback

A writing system is the collection of scripts and orthographic rules required to represent a language as text. The TextInfo class represents a writing system.

Use the CultureInfo.TextInfo property to obtain the TextInfo object for a particular CultureInfo object. If a security decision depends on a string comparison or a case-change operation, use the CultureInfo.TextInfo property of the object returned by the CultureInfo.InvariantCulture property to ensure that the behavior of the operation is consistent regardless of the system culture settings.


The user might use Regional and Language Options (or Regional Options or Regional Settings) in Control Panel to override the values associated with the current culture of Windows. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture. If the CultureInfo.UseUserOverride property is set to true, the property values of the objects returned by the CultureInfo.DateTimeFormat, CultureInfo.NumberFormat, and CultureInfo.TextInfo properties are also retrieved from the user settings. If the user settings are incompatible with the culture associated with the CultureInfo (for example, if the selected calendar is not one of the OptionalCalendars), the results of the methods and the values of the properties are undefined.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
