Add a Visual studio project items into the project dynamically

Hi,

How can I add the visual studio project items dynamically. I have created the project dynamically.

If I want to add the xxx.cs file|xxx.png files dynamically. I have refereed many websites those sites are mentioned add the items in solution explorer only. But I want to add the files into the folder. For Ex.

The project structure is, 

>Properties

>References

>Images

>Common

I want to add the images into the Images folder and Add the cs files in Common folder. 

Please any one update about this.

Thanks,

Abbas K
