    {
                 


        

Answer 1

Use Clipboard.GetDataObject to get bitmap and convert it into bitmapSource. Also, be aware that Bitmap.GetHbitmap() leaks memory unless you call DeleteObject on it.

So, correct solution would be to dispose the IntPtr after use. Declare the method at class level and use it from your code:

// at class level
[System.Runtime.InteropServices.DllImport("gdi32.dll")]
public static extern bool DeleteObject(IntPtr hObject);

if (Clipboard.ContainsImage())
{
    IDataObject clipboardData = Clipboard.GetDataObject();
    if (clipboardData != null)
    {
        if (clipboardData.GetDataPresent(System.Windows.Forms.DataFormats.Bitmap))
        {
            System.Drawing.Bitmap bitmap = (System.Drawing.Bitmap)clipboardData.GetData(System.Windows.Forms.DataFormats.Bitmap);
            IntPtr hBitmap = bitmap.GetHbitmap();
            try
            {
                ImageUIElement.Source = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
                Console.WriteLine("Clipboard copied to UIElement");
            }
            finally 
            {
                DeleteObject(hBitmap)
            }
        }
    }
}
