Load image from resource and apply to Image.source

Question

I'm using

BitmapImage  sharerimg;
sharerimg = new BitmapImage(new Uri("F:/workspace/wpf/NetworkMFServer/NetworkMFServer/imageresources/sharer.png"));
Image im = new Image();
im.Source = sharerimg;

But i add image to resources and code this

Assembly assembly = Assembly.GetExecutingAssembly();
            string strBaseName = assembly.GetName().Name + ".Properties.Resources";
            ResourceManager rm = new ResourceManager(strBaseName, assembly);
Image im = new Image();
im=(Image)rm.GetObject("sharer");

However this show error

" Can not cast 'System.Drawing.Bitmap' to 'System.Windows.Controls.Image'"

How can i use image resouce to apply System.Windows.Controls.Image .Source property?

My image variable 'im' is System.windows.controls.image type and resource image file 'Resources.sharer' is System.Drawing.Bitmap type. What is fast way using this resource to im — Lightstar, Jan 22 '15 at 08:10
clientimg = new BitmapImage(new Uri("pack://application:,,,/Resources/client.png")); ...And 'resources/client.png' There is no resource — Lightstar, Jan 22 '15 at 11:10

As per MSDN exmaple you should do like this -

Image myImage3 = new Image();
BitmapImage bi3 = new BitmapImage();
bi3.BeginInit();
bi3.UriSource = new Uri("smiley_stackpanel.PNG", UriKind.Relative);
bi3.EndInit();
myImage3.Stretch = Stretch.Fill;
myImage3.Source = bi3;

Is it use resource? Is 'smiley_stackpanel.PNG' not local file? – Lightstar Jan 22 '15 at 07:36
For resource added SO link . Please check second link – Amit Jan 22 '15 at 07:38
You mean to say if you try that code asm.GetManifestResourceStream("path.to.resource"); you are getting empty stream? – Amit Jan 22 '15 at 08:10
Yes.. I correctly add image file to my project resouces – Lightstar Jan 22 '15 at 08:13

Please note that you can avoid the BeginInit/EndInit sequence when you use the BitmapImage constructor with Uri parameter (as used in the question): `var bi = new BitmapImage(new Uri(...));` – Clemens Jan 22 '15 at 08:55
@LightStar- You used GetCallingAssembly or GetExecutingAssembly function? – Amit Jan 22 '15 at 09:38
Also note - The GetManifestResourceStream method will always returns NULL if the resource ’built action’ property is not set to ’embedded resource’. – Amit Jan 22 '15 at 09:40
