所以我需要将图像以及其他一些字符串（例如名称）上传到我的 Mysql 数据库中...我能够将名称添加到 Mysql DB 中，但我无法对图像执行此操作。我将图像转换为字节 []，现在我被卡住了..这是我使用的代码

private Stream stream = new MemoryStream();
    private CancellationTokenSource cts;

    public MainPage()
    {
        this.InitializeComponent();
    }

    private async void buttonUpload_Click(object sender, RoutedEventArgs e)
    {
        FileOpenPicker open = new FileOpenPicker();
        open.SuggestedStartLocation = PickerLocationId.PicturesLibrary;
        open.ViewMode = PickerViewMode.Thumbnail;

        // Filter to include a sample subset of file types
        open.FileTypeFilter.Clear();
        open.FileTypeFilter.Add(".bmp");
        open.FileTypeFilter.Add(".png");
        open.FileTypeFilter.Add(".jpeg");
        open.FileTypeFilter.Add(".jpg");

        // Open a stream for the selected file
        StorageFile file = await open.PickSingleFileAsync();

        // Ensure a file was selected
        if (file != null)
        {
            // …
