StringFormat.SetDigitSubstitution(Int32, StringDigitSubstitute) StringFormat.SetDigitSubstitution(Int32, StringDigitSubstitute) StringFormat.SetDigitSubstitution(Int32, StringDigitSubstitute) StringFormat.SetDigitSubstitution(Int32, StringDigitSubstitute) Method

Definition

Specifies the language and method to be used when local digits are substituted for western digits.

public:
 void SetDigitSubstitution(int language, System::Drawing::StringDigitSubstitute substitute);
public void SetDigitSubstitution (int language, System.Drawing.StringDigitSubstitute substitute);
member this.SetDigitSubstitution : int * System.Drawing.StringDigitSubstitute -> unit
Public Sub SetDigitSubstitution (language As Integer, substitute As StringDigitSubstitute)

Parameters

language
Int32 Int32 Int32 Int32

A National Language Support (NLS) language identifier that identifies the language that will be used when local digits are substituted for western digits. You can pass the LCID property of a CultureInfo object as the NLS language identifier. For example, suppose you create a CultureInfo object by passing the string "ar-EG" to a CultureInfo constructor. If you pass the LCID property of that CultureInfo object along with Traditional to the SetDigitSubstitution(Int32, StringDigitSubstitute) method, then Arabic-Indic digits will be substituted for western digits at display time.

substitute
StringDigitSubstitute StringDigitSubstitute StringDigitSubstitute StringDigitSubstitute

An element of the StringDigitSubstitute enumeration that specifies how digits are displayed.

Examples

The following example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:

  • Sets, for the StringFormat, the language to be used and the substitution method to be used.

  • Draws the string.

  • Repeats the above two steps for two different languages (Arabic and Thai).

The National substitution method and Traditional substitution method are demonstrated for each of the two languages. The National method displays digits according to the official national language of the user's locale. The Traditional method displays digits according to the user's native script or language, which may be different from the official national language.
