"Creating a doubly linked list with a single pointer for each node in C# involves defining a Node class and then creating the links. Here's an example:nn```csharpnpublic class Node {n public int data;n public Node next;n public Node prev;n}npublic static void AddNode(ref Node head, int data) {n Node newNode = new Node() {n data = data,n prev = null,n next = headn };n if (head != null) {n head.prev = newNode;n }n head = newNode;n}n```
