Detailed explanation of C# using generic methods to design and implement one-way linked list

Here is an example using a generic node class and a LinkedList<T> class that contains the Insert method for inserting a new node and updating the current node after insertion. At the same time, the GetCurrentValue method is used to get the value of the current node and convert it to an int type.

1. First design a generic node class Node<T>

 /// &lt;summary&gt;
 /// Define generic node classes /// &lt;/summary&gt;
 public class Node&lt;T&gt;(T data)
 {
     public T Data { get; set; } = data;
     public Node&lt;T&gt;? Next { get; set; } = null;
 }

2. Design a generic linked list class LinkedList<T>

Define a LinkedList<T> class containing Insert and GetCurrentValue methods:

 /// &lt;summary&gt;
 /// Define generic linked list class LinkedList<T> /// &lt;/summary&gt;
 public class LinkedList&lt;T&gt; where T : struct
 {
     private Node&lt;T&gt;? head;
     private Node&lt;T&gt;? current;
 
     public void Insert(T value)
     {
         var newNode = new Node&lt;T&gt;(value);
 
         if (head == null)
         {
             head = newNode;
             current = newNode;
         }
         else
         {
             Node&lt;T&gt; temp = head;
             while ( != null)
             {
                 temp = ;
             }
              = newNode;
             current = newNode;
         }
     }
     // Define the GetCurrentValue() method to get the current node     public int GetCurrentValue()
     {
         if (head == null)
         {
             throw new InvalidOperationException("The linked list is empty.");
         }
 
         return LinkedList&lt;T&gt;.ConvertToInt();
     }
     // Convert <T> to int type     private static int ConvertToInt(T value)
     {
         return checked((int)(object)value);
     }
 }

Use a similar method to add other methods in the LinkedList<T> class.

3. Create an instance of the LinkedList<int> class

Create an instance of the LinkedList<int> class, insert some nodes, and display the value of the current node:

var linkedList = new LinkedList&lt;int&gt;();
 
(5);
(10);
(15);
 
(()); // Output: 15

This example assumes that type T can be converted to int. In practical applications, please make sure that the type of T meets your needs.
