UWP Windows 10 C＃将数据写入.txt文件中的新行

Question

您好我正在为Windows 10开发UWP（通用Windows平台）应用程序，但遇到了一个问题。我无法弄清楚如何在txt文件中的新行上写入数据，因为我写的数据只是覆盖了第一行的数据。非常感谢任何帮助！欢呼声。

写入/读取代码低于Writing to and reading from a text file - C# Windows Universal Platform App Windows 10

private async void SaveButton_Click(object sender, RoutedEventArgs e)
    {
        //Create the text file to hold the data
        Windows.Storage.StorageFolder storageFolder = Windows.Storage.ApplicationData.Current.RoamingFolder;
        Windows.Storage.StorageFile ticketsFile = await storageFolder.CreateFileAsync("tickets.txt", Windows.Storage.CreationCollisionOption.ReplaceExisting);

        string ingredients = IngredientBox.Text;
        //Write data to the file
        await Windows.Storage.FileIO.WriteTextAsync(ticketsFile, ingredients);

        //read file
        string savedTickets = await Windows.Storage.FileIO.ReadTextAsync(ticketsFile);
        var path = Windows.Storage.ApplicationData.Current.RoamingFolder.Path;

        StepsBox.Text = path;
    }
