Form.InputLanguageChanged Event


更改窗体的输入语言后发生。Occurs after the input language of the form has changed.

 event System::Windows::Forms::InputLanguageChangedEventHandler ^ InputLanguageChanged;
public event System.Windows.Forms.InputLanguageChangedEventHandler InputLanguageChanged;
member this.InputLanguageChanged : System.Windows.Forms.InputLanguageChangedEventHandler 
Public Custom Event InputLanguageChanged As InputLanguageChangedEventHandler 


下面的示例演示如何使用此成员。The following example demonstrates the use of this member. 在此示例中,事件处理程序报告 InputLanguageChanged 事件的发生。In the example, an event handler reports on the occurrence of the InputLanguageChanged event. 此报表可帮助你了解何时发生事件,并可帮助你进行调试。This report helps you to learn when the event occurs and can assist you in debugging. 若要报告多个事件或频繁发生的事件,请考虑将 MessageBox.Show 替换为 Console.WriteLine 或将消息附加到多行 TextBox中。To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

若要运行示例代码,请将其粘贴到包含名为 Form1Form 类型实例的项目中。To run the example code, paste it into a project that contains an instance of type Form named Form1. 然后,确保事件处理程序与 InputLanguageChanged 事件关联。Then ensure that the event handler is associated with the InputLanguageChanged event.

private void Form1_InputLanguageChanged(Object sender, InputLanguageChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "InputLanguage", e.InputLanguage );
messageBoxCS.AppendFormat("{0} = {1}", "Culture", e.Culture );
messageBoxCS.AppendFormat("{0} = {1}", "CharSet", e.CharSet );
MessageBox.Show(messageBoxCS.ToString(), "InputLanguageChanged Event" );
Private Sub Form1_InputLanguageChanged(sender as Object, e as InputLanguageChangedEventArgs) _ 
     Handles Form1.InputLanguageChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "InputLanguage", e.InputLanguage)
    messageBoxVB.AppendFormat("{0} = {1}", "Culture", e.Culture)
    messageBoxVB.AppendFormat("{0} = {1}", "CharSet", e.CharSet)
    MessageBox.Show(messageBoxVB.ToString(),"InputLanguageChanged Event")

End Sub


您可以使用此事件根据对窗体的输入语言所做的更改对窗体的外观和文本进行更改。You can use this event to make changes to your form's appearance and text based on changes made to the input language of the form.
