How to make use of fluent interfaces and technique chaining in C#

When working in purposes you would possibly usually discover that the supply code has change into so complicated that it’s obscure and keep. Fluent interfaces and technique chaining are two ideas that try and make your code readable and easy. This article examines fluent interfaces and technique chaining and how one can work with them in C#.

To work with the code examples supplied on this article, it is best to have Visual Studio 2019 put in in your system. If you don’t have already got a replica, you possibly can obtain Visual Studio 2019 right here. 

Create a console utility challenge in Visual Studio

First off, let’s create a .NET Core console utility challenge in Visual Studio. Assuming Visual Studio 2019 is put in in your system, observe the steps outlined under to create a brand new .NET Core console utility challenge in Visual Studio.

1. Launch the Visual Studio IDE.
2. Click on “Create new project.”
3. In the “Create new project” window, choose “Console App (.NET Core)” from the record of templates displayed.
4. Click Next. 
5. In the “Configure your new project” window, specify the title and site for the brand new challenge.
6. Click Create.

This will create a brand new .NET Core console utility challenge in Visual Studio 2019. We’ll use this challenge within the subsequent sections of this text.

Fluent interfaces and technique chaining defined

Method chaining is a method through which strategies are referred to as on a sequence to type a series and every of those strategies return an occasion of a category. These strategies can then be chained collectively in order that they type a single assertion. A fluent interface is an object-oriented API that relies upon largely on technique chaining. The objective of a fluent interface is to scale back code complexity, make the code readable, and create a website particular language (DSL). It is a kind of technique chaining through which the context is maintained utilizing a series.

You would possibly already be utilizing technique chaining in your purposes, knowingly or unknowingly. The following code snippet illustrates how strategies are chained.

var information = authorList.Where(a => a.Country == "USA")
                     .OrderBy(a => a.AuthodId)
                     .ToRecord();

In technique chaining, while you name a way the context flows from the tactic referred to as to a different technique, i.e., the subsequent technique within the chain. Hence the time period “chaining” is used to explain this sample.
