What do you mean by plugins? The obvious way to do this in C# would be to create a class library that you can link to other programs.

I know about dynamic library (dll file).My problem is:
1.How to the plugin call funtions from the main program ?
2.How to the main program get the result from the plugin ?

I think you probably need to investigate the use of COM objects, which are more suited to what you are asking. See http://www.codeproject.com/Articles/633/Introduction-to-COM-What-It-Is-and-How-to-Use-It.
