I have instantiated several System.Drawing.Icon Objects. Note that these are created at runtime and are not stored and loaded from the file system. I would like to place these images in my WPF application.<\/p>\n

However as I have discovered over the last few hours, it is not possible to simply add an object such as an system.drawing.image or icon directly to the canvas\/stack panel, nor is it possible to set the source of a System.Windows.Controls.Image to an image or icon not stored within the file system (or so it seems to me).<\/p>\n

Any ideas?<\/p>\n

    This has worked for me dynamically setting a WPF Image with bytes loaded from a bitmap that was either dynamically generated or loaded from disk:<\/p>\n

    using System;\nusing System.Collections.Generic;\nusing System.Text;\nusing System.Windows;\nusing System.Windows.Controls;\nusing System.Windows.Data;\nusing System.Windows.Documents;\nusing System.Windows.Input;\nusing System.Windows.Media;\nusing System.Windows.Media.Imaging;\nusing System.Windows.Navigation;\nusing System.Windows.Shapes;\n\nusing System.IO;\nusing System.Drawing.Imaging;\n\nnamespace Examples\n{\n    public class Util\n    {\n        private static void SetBitmap(Image imgDest, Bitmap bmpSource)\n        {\n            byte[] imageBytes;\n            using (MemoryStream stream = new MemoryStream())\n            {\n                bmpSource.Save(stream, ImageFormat.Png);\n\n                imageBytes = stream.ToArray();\n            }\n\n            BitmapImage bitmapImage = new BitmapImage();\n            bitmapImage.BeginInit();\n            bitmapImage.StreamSource = new MemoryStream(imageBytes);\n            bitmapImage.EndInit();\n\n            imgDest.Source = bitmapImage;\n        }\n    }\n}\n<\/code><\/pre>\n<\/li>\n<\/ol>\n
