Finally, we comes with the C# language. C# supports all OO features mentioned in previous articles in language level. So, our implementation is quite straight forward. Just check the source code in my skydrive: http://cid-481cbe104492a3af.office.live.com/browse.aspx/share/dev/TestOO. In the TestCSObject-{date}.zip file.
Lastly, I drew a simple table to compare and summarize the OO supports in the four leading languages:
| C/gtk+ | C++/Qt | Java | C# | |
| Basic Features | ||||
| Encapsulation | library | good design | Y | Y |
| Inheritance | library | Y | Y | Y |
| Polymorphism | function pointer | Y | Y | Y |
| Advanced Features | ||||
| Property | library | library | reflection feature | Y |
| Meta Info | library | library | annotations | attributes |
| Event Driven | library(signals) | library(signals/slots) | events/listeners | delegates/events/handlers |
| Measurements (Using a test application to demostrate above 5 features) | ||||
| Compiler | mingw32-gcc/3.4 | mingw32-g++/3.4 | JDK/1.6.20 | VC#/2005 |
| Library | gtk+/2.16.6 | Qt/4.3.5 | Java/6.0 | .NET/2.0 |
| Source Size | 19.09 KB | 7.28 KB (+10.17 KB) * | 13.18 KB | 6.28 KB |
| Binary Size | 32.69 KB | 34.00 KB | 9.48 KB | 5.50 KB |
| Runtime Size | 1.46 MB | 2.00 MB | 15.54 MB | 23.84 MB |
