Difference between DLL and a class library?

Hi,
could somebody please explain me which is the difference between using a dll to store custom functions in my project, instead of a normal class (.cs file) for the same purpose? What are the benefits and disadvantages (if any)?

Thank you

hi, if you kept the custom function class in your project then it's not resuable, maitenance is not easy (due to multiple copies etc.,), still you can reuse by copying the class into your required project. but DLL means just you can add reference.

if you have it as DLL then it's resuable, easy maitenance etc.,
