Static linking in C# (Possible or not)

Question

Hi all, I am back again with a doubt which mos tof you ll find silly, I am creating a library so that i can use it in other programs, would be grateful if you can post your suggestions on ho to do it. As far as i can think, i am making a class and putting in allthe functions of the library there, and then wherever required use that namespace and access the methds using an object of the library class, Is there any way i can just have a collection of functions (Like C) and just use them without having to create a class? Thanking you for your time Siddhartha
