C# .dll and .exe

Thanks moderators..

Hi Satyabrtata,

1.EXE is an extension used for executable files while DLL is the extension for a dynamic link library.
2.An EXE file can be run independently while a DLL is used by other applications.
3.A DLL file can be reused by other applications while an EXE cannot.
4.Exe is for single use whereas you can use Dll for multiple use
5.Dll is an In-Process Component whereas EXE is an OUt-Process Component.
6.You can create an objects of Dll but not of the EXE.


Thanks

Please see this previous thread for the difference between a C# .exe and .dll:

You can add references to other assemblies (normally .dlls) to your program using the /reference (or just /r) compiler switch:

If you're using Visual Studio, the IDE will do this for you if you right click on your project in Solution Explorer, choose Add Reference from the dropdown list, navigate to the assembly you want and OK it.
