When to use classes?

Question

Hello all. I created an ASP.NET/C# application with over 10,000 lines of code. Within the code has numberous functions that I created and is used many times by the application. My question is when is the right time to create a class(es) and how do I used the classes? How many lines of code is too much?
Thank you in advanced for all your help.

A class represents an object or entity. An object has properties. So if your program has some entities .. for example you have a Member in a Website. A member can be a male or female has a date of birth and Email. So you can create a class called Member with properties - Gender DOB and Email. This is called object-oriented programming where a Member is an object. In a website if you just have some functions and there are no entities or objects you can create helper classes. These classes are used to make the code more readable and modular. I would recommend to create classes for similar functions. For example if you are reading writing and updating database you can have a class called DatabaseHelper.
