Implementation

You already know some basic information about graphs, including nodes, edges, and two methods of representation, namely using an adjacency list and matrix. However, how you can use such a data structure in your applications? In this section, you will learn how to implement a graph using the C# language. To make your understanding of this content easier, two examples will be provided.

Node

To start with, let’s take a look at the code of a generic class representing a single node in a graph. Such a class is named Node and its code is as follows:

public class Node<T>
{
    public int Index { get; set; }
    public required T Data { get; set; }
    public List<Node<T>> Neighbors { get; set; } = [];
    public List<int> Weights { get; set; } = [];
    public override string ToString() => $"Index: {Index}.
