I don't know what you can :-), but most developers certainly can. It also depends on what kind of noise is required. Generally, one way I would strongly recommend would be the famous library AForge.NET. Please see: AForge.NET :: Framework Features — Noise Generation filters[^].

You will find all you need. If not exactly all, you can pretty easily add your own filter with your own noise generating algorithm.

Good luck.

thank you vary much for your reply.
but please, tell me how can i add this library to visual basic.net to use the filters.

You are welcome. What do you mean "how"? Exactly as any other .NET library. Or you can add this library in the form of source code in your solution and add the reference to the project to your project, as it is always done. And then you can simply build the whole solution, all together, which I highly recommend.
