System.Net如何实现？

Question

I'm learning networking in C#, and I realized that I'm completely dependent on the System.Net framework for networking (not that this is a bad thing). I don't understand how, using standard language features, without relying on any framework, you can connect to a network via C#.

Answer 1

Like a lot of managed runtimes the underlying code relies on native functionality. I could list the Win32 APIs that are used or you could just look at the source :) I prefer the latter.

.NET source has been open for about 4 years now .

Answer 2

The System.NET framework simply provides a managed wrapper around the windows API. If you want to see how MS does it, you can open the Assembly with a decompiler (Reflector or ILSpy) and look at the code.
