C#数据结构之循环链表的实例代码
很多人都不知道C#数据结构中循环链表的代码怎么写，下面小编为大家整理了C#数据结构之循环链表的实例代码，希望能帮到大家！
复制代码 代码如下:
public class Node
{
public object Element;
public Node Link;
public Node()
{
Element = null;
Link = null;
}
public Node(object theElement)
{
Element = theElement;
Link = null;
}
}
复制代码 代码如下:
public class LinkedList
{
//头结点
protected Node Header;
private int count;
public LinkedList()
{
count = 0;
Header = new Node("header");
Header.Link = Header;
}
public bool IsEmpty()
{
return (Header.Link == null);
}
public void MakeEmpty()
{
Header.Link = null;
}
public void PrintList()
{
Node current = new Node();
current = Header;
while (current.Link.Element.ToString() != "header")
{
Console.WriteLine(current.Link.Element);
current = current.Link;
}
}
private Node FindPrevious(object n)
{
Node current = Header;
while (!(current.Link == null) && current.Link.Element != n)
{
current = current.Link;
}
return current;
}
private Node Find(object item)
{
Node current = new Node();
current = Header.Link;
while (current.Element != item)
{
current = current.Link;
}
return current;
}
public void Insert(object newItem, object after)
{
Node current = new Node();
Node newNode = new Node(newItem);
current = Find(after);
newNode.Link = current.Link;
current.Link = newNode;
count++;
}
public void Remove(object n)
{
Node p = FindPrevious(n);
if (!(p.Link == null))
{
p.Link = p.Link.Link;
count--;
}
}
public void InsertFirst(object n)
{
Node current = new Node(n);
current.Link = Header;
Header.Link = current;
count++;
}
public Node Move(int n)
{
Node current = Header.Link;
Node tmp;
for (int i = 0; i <= n; i++)
{
current = current.Link;
}
if (current.Element.ToString() == "header")
{
current = current.Link;
}
tmp = current;
return tmp;
}
public Node GetFirst()
{
return Header;
}
}
