remove a node from the middle of a linked list in csharp

To remove a node from the middle of a linked list in C#, you need to perform the following steps:

  1. Traverse the linked list to find the node to be removed (let's call this node nodeToRemove)
  2. Identify the previous node (previousNode) of the node to be removed
  3. Update previousNode.next to bypass nodeToRemove
  4. Remove the reference to nodeToRemove to allow for garbage collection

Here's one possible implementation that assumes the linked list is implemented using a custom LinkedList class with Add, Remove and Traverse methods:

main.cs
public void RemoveNodeFromMiddle(int value)
{
    Node currentNode = head;
    Node previousNode = null;

    while (currentNode != null && currentNode.Value != value)
    {
        previousNode = currentNode;
        currentNode = currentNode.Next;
    }

    if (currentNode == null)
    {
        // node not found
        return;
    }

    // node found; remove it
    previousNode.Next = currentNode.Next;
    currentNode.Next = null; // remove reference to currentNode
}

Note that this implementation assumes that the linked list does not contain duplicate values. If duplicate values are allowed, you may need to modify the implementation to remove all instances of the value.
