C# file size limit

Question

I have a website built with ASP.NET (.NET 2.0). I have a lot of classes in my business logic, and I keep all of them in one file (BL.cs).

I now got to a stage where I have 11,000 lines of code in this file. Is this a problem - should I separate it into several files, each class in a different file? Is there a limit that the cs file shouldn't exceed?

Answer 1

I stick to the following rule: 1 file per class (unless for nested classes of course). 11,000 lines of code in a single file looks monstrous.

Answer 2

You should keep each class in separate file for better readability and managability.

Answer 3

To be honest I don't know if there is a size limit, but 11.000 lines of code is a lot to handle in a single file.

You will find that VS runs a lot smoother if you split the code into multiple files and it will make it easier for you and your fellow developers to focus on a specific set of classes for any given task.

Programming is all about building complex systems from simple parts. Storing all your parts in a single, giant file goes against that idea.
