ImageSource to string in WPF and C# ?

[M-Dayyan]

Hi,

I have the below XAML code :

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    DataContext="{Binding RelativeSource={RelativeSource Self}}"
    WindowStartupLocation="CenterScreen"
    Title="Window1" Height="300" Width="300">
    
    <Grid>
        <Image x:Name="TestImage" Source="{Binding Path=ImageSource}" />
    </Grid>

</Window> 

Now, I'm gonna set the `TestImage` with the below method :

Image Base64StringToImage(string base64ImageString)
{
    try
    {
        byte[] b;
        b = Convert.FromBase64String(base64ImageString);
        MemoryStream ms = new System.IO.MemoryStream(b);
        System.Drawing.Image img = System.Drawing.Image.FromStream(ms);

        //////////////////////////////////////////////
        //convert System.Drawing.Image to WPF image
        System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(img);
        IntPtr hBitmap = bmp.GetHbitmap();
        System.Windows.Media.ImageSource imageSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());

        Image wpfImage = new Image();
        wpfImage.Source = imageSource;
        wpfImage.Width = wpfImage.Height = 16;
        //////////////////////////////////////////////

        return wpfImage;
    }
    catch
    {
        Image img1 = new Image();
        img1.Source = new BitmapImage(new Uri(@"/passwordManager;component/images/TreeView/empty-bookmark.png", UriKind.Relative));
        img1.Width = img1.Height = 16;
        return img1;
    }
} 

I've used the following code, but it doesn't work :

public string ImageSource { get; set; }
ImageSource = Base64StringToImage("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").Source.ToString(); 

Actually , I have a problem with converting ImageSource to string !
Would you please guide me, how I can do it ?
Thanks.
