Edge

As mentioned in the short introduction to the topic of graphs, a graph consists of nodes and edges. As a node is represented by an instance of the Node class, the Edge generic class can be used to represent an edge. The suitable part of code is as follows:

public class Edge<T> 
{ 
    public Node<T> From { get; set; } 
    public Node<T> To { get; set; } 
    public int Weight { get; set; } 
 
    public override string ToString() 
    { 
        return $"Edge: {From.Data} -> {To.Data},  
            weight: {Weight}"; 
    } 
} 

The class contains three properties, namely representing nodes adjacent to the edge (From and To), as well as the weight of the edge (Weight). Moreover, the ToString method is overridden to present some basic information about the edge.
