When to use classes?

Maria

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.

Hi friend,

The no of lines is depends on the function of code..you can use the class when you are doing same process for many times.
