初学C#记录历程,记录心情。
节点类和链表类参考前篇。
在接口IList中增加:
void CreateListHead(int length); //创建单链表,在头部插入结点
在LinkList类中创建方法:

1 /// <summary> 2 /// 创建单链表 3 /// </summary> 4 /// <param name="length">单链表长度</param> 5 public void CreateListHead(int length) 6 { 7 if (length <= 0) 8 { 9 Console.WriteLine("Error! the length of list is incorrect.please run again"); 10 return; 11 } 12 else 13 { 14 Console.WriteLine("Please input the node data of the list:"); 15 for (int i = length; i > 0; i--) 16 { 17 T item = default(T); //定义新结点数据域 18 item = (T)Convert.ChangeType(Console.ReadLine(), typeof(T)); //从键盘输入的字符串转换成T。当不知道当前类型要转换成什么类型的情况下,用Convert.ChangeType(value,typeof(type)) 19 LinkNode<T> NewNode = new LinkNode<T>(item);//new一个新结点 20 NewNode.Next = this.Head; 21 this.Head = NewNode; 22 //NewNode.Data = item; 23 } 24 } 25 }
验证创建是否正确:

1 static LinkList<int> MyList = new LinkList<int>(); 2 static LinkNode<int> node; 3 4 private static LinkNode<int> PrintData(LinkNode<int> node) 5 { 6 node = MyList.Head; 7 while (node != null) 8 { 9 Console.WriteLine("The data of List are:{0}", node.Data); 10 node = node.Next; 11 } 12 return node; 13 } 14 15 static void Main(string[] args) 16 { 17 18 Console.Write("Pleae input the lenght of your ListLink,n= "); 19 string str = Console.ReadLine(); 20 int n; 21 n= Convert.ToInt32(str); 22 MyList.CreateListHead(n); 23 24 if (MyList.Head == null) 25 { 26 Console.WriteLine("List is empty"); 27 } 28 else 29 { 30 Console.WriteLine("After created:"); 31 node = PrintData(node); 32 } 33 Console.WriteLine("Please Enter and exit.Thanks!"); 34 Console.ReadLine(); 35 }
