Avoiding duplication

Code can be either DRY or WET. WET code stands for Write Every Time and is the opposite of DRY, which stands for Don’t Repeat Yourself, as previously mentioned. The problem with WET code is that it is the perfect candidate for bugs. Let’s say your test team or a customer finds a bug and reports it to you. You fix the bug and pass it on, only for it to come back and bite you as many times as that code is encountered within your computer program.

Duplicate C# code can lead to increased maintenance costs. When the same code is replicated in multiple places within a project, it becomes harder to make consistent updates and bug fixes. This redundancy not only consumes more time but also introduces the risk of inconsistencies and errors.

For instance, consider the following code snippet:

public void CalculateTotalPrice(){
    // Code to calculate the total price
}
public void CalculateDiscountedPrice()
{
