I have to make an mp3 sound recorder to record through mike. So, I plan to
use lame as mp3 encoder which is written in C. I am unable to import its dll
in C# project as a reference because it says that the dll formed is not a
valid managed dll. So, I compiled the project as a static library (.lib) and
used it in a cpp project. I was able to use it successfully this way.
Secondly, I was also unable to find any sound recording library in C#. First.
please tell me the library(if any) for sound recording in C# and secondly, is
there any way I can use this C Application in that C# project.

That's what i'm developing right now - sound recording with wav-to-mp3 conversion.

For recording i use Windows Multimedia API, which is the easies way.
There is a full-featured example on codeproject.com, which i used as a start:

http://www.codeproject.com/cs/media/cswavrec.asp?print=true

It shows how to implement a wav player/recorder in c# using p/invoke of winmm.dll
And i'm positive it will work for you


If you would have any questions regarding use of that example, don't hesitate to ask me

Good luck,
Andrey
