AsyncCompletedEventHandler

範例

以下程式碼範例示範 OnLoadCompleted 如何使用事件處理器接收通知，表示 .wav 檔案內容已被載入。 此程式碼範例是本類別更大範例 SoundPlayer 的一部分。

// Handler for the LoadCompleted event.
void player_LoadCompleted( Object^ /*sender*/, AsyncCompletedEventArgs^ /*e*/ )
{
   String^ message = String::Format( "LoadCompleted: {0}", this->filepathTextbox->Text );
   ReportStatus( message );
   EnablePlaybackControls( true );
}

// Handler for the LoadCompleted event.
private void player_LoadCompleted(object sender, 
    AsyncCompletedEventArgs e)
{   
    string message = String.Format("LoadCompleted: {0}", 
        this.filepathTextbox.Text);
    ReportStatus(message);
    EnablePlaybackControls(true);
}

' Handler for the LoadCompleted event.
Private Sub player_LoadCompleted(ByVal sender As Object, _
    ByVal e As AsyncCompletedEventArgs)

    Dim message As String = [String].Format("LoadCompleted: {0}", _
        Me.filepathTextbox.Text)
    ReportStatus(message)
    EnablePlaybackControls(True)

End Sub

備註

當 .wav 檔案載入完成時，此事件會被觸發。 事件參數表示聲音載入是否成功完成或失敗。
