Gets the character set associated with the new input language.


Gets the locale of the input language.


Gets a value indicating the input language.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

You can use the data from the InputLanguageChangedEventArgs to make decisions about whether to change Input Method Editors (IMEs) or swap right-to-left values. You can also change the CurrentCulture of a thread and the CurrentUICulture properties so that different resources get picked up.

An InputLanguageChangedEventArgs identifies the locale and the character set of the new input language.

The InputLanguageChanging event precedes the InputLanguageChanged event.

The following example creates a new Form and attaches an event handler to the InputLanguageChanged event. This event changes the IMEmode when the input language changes to Japanese.

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

public class Form1 : System.Windows.Forms.Form
	RichTextBox rtb = new RichTextBox();
	public Form1()
		rtb.Dock = DockStyle.Fill;
		this.InputLanguageChanged += new InputLanguageChangedEventHandler(languageChange);
	private void languageChange(Object sender, InputLanguageChangedEventArgs e)
		// If the input language is Japanese.
		// set the initial IMEMode to Katakana.
		if (e.InputLanguage.Culture.TwoLetterISOLanguageName.Equals("ja"))
			rtb.ImeMode = System.Windows.Forms.ImeMode.Katakana;
	public static void Main(string[] args)
		Application.Run(new Form1());
