Change Window Form Application Background from Embeded Resource

This is a note about changing the background image of .Net Win Form Application.
Assumption:

1. the image resources is embedded.
2. you have no idea about the full name of the background image. (tricky ...)
   

The following name space is required:

• using System.Reflection;
• using System.IO;
• using System.Drawing;

Here is the code to load the resource from assembly.

1. Assembly a = Assembly.GetExecutingAssembly();
2. string[] resNames = a.GetManifestResourceNames();
3. foreach (string s in resNames)
4. {
5. if (s.EndsWith(".png"))
6. {
7. Stream imgStream = a.GetManifestResourceStream(s);
8. this.BackgroundImage = Bitmap.FromStream(imgStream) as Bitmap;
9. break;
10. }
11. }
    

With using this code the resource can be load dynamically.
