c# 泛型集合类用起来十分的方便快捷。在这篇随笔里面,我将用链表来模拟c#中的 list﹤t﹥ 类的行为,废话不多说,下面来看我的实现代码,代码中已经写了注释,所以不再对代码进行额外的说明:
using system.collections;
class mylist﹤t﹥
{
private mylistnode firstnode;//首节点
private int count;//c# 泛型集合-节点计数
public mylist()
{
this.firstnode = null;
this.count = 0;
}
//c# 泛型集合-得到list长度
public int getlength()
{
return this.count;
}
//增加一个节点
public void addelement(t data)
{
mylistnode first = this.firstnode;
if(first==null)
{
this.firstnode=new mylistnode(data);
this.count++;
return;
}
while (first.next != null)
{
first = first.next;
}
first.next = new mylistnode(data);
this.count++;
}
//c# 泛型集合-删除一个节点
public bool remove(t data)
{
mylistnode first = this.firstnode;
if (first.data.equals(data))
{
this.firstnode = first.next;
this.count--;
return true;
}
while (first.next!=null)
{
if (first.next.data.equals(data))
{
first.next = first.next.next;
this.count--;
return true;
}
}
return false;
}
//c# 泛型集合-得到指定索引上的集合元素
public t getatindex(int index)
{
int innercount = 1;
mylistnode first = this.firstnode;
if (index ﹥ count)
{
throw new exception(index out of boundary);
}
; else
{
while (innercount ﹤ index)
{
first = first.next;
innercount++;
}
return first.data;
}
}
//在指定的索引上插入新的元素
public void insertatindex(int index,t data)
{
int innercount = 1;
mylistnode first = this.firstnode;
if (index ﹥ count)
{
throw new exception(index out of boundary);
}
if (index == 1)
{
this.firstnode = new mylistnode(data);
this.firstnode.next = first;
}
else
{
while (innercount ﹤ index - 1)
{
first = first.next;
innercount++;
}
mylistnode newnode = new mylistnode(data);
newnode.next = first.next;
first.next = newnode;
}
this.count++;
}
//c# 泛型集合-删除指定索引上的集合元素
public void removeatindex(int index)
{
int innercount = 1;
mylistnode first = this.firstnode;
if (index ﹥ count)
{
throw new exception(index out of boundary);
}
if (index == 1)
{
this.firstnode = first.next;
}
else
{
while (innercount ﹤ index - 1)
{
first = first.next;
innercount++;
}
first.next = first.next.next;
}
this.count--;
}
//c# 泛型集合-删除集合中的所有元素
public void removeall()
{
this.firstnode = null;
this.count = 0;
}
//为实现该集合类能用foreach进行遍历
public ienumerator getenumerator()
{
mylistnode first = this.firstnode;
while (first!= null)
{
yield return first.data;
first = first.next;
}
}
//内部节点类
private class mylistnode
{
public t data { get; set; }//节点上的元素值
public mylistnode next { get; set; }//节点的下一个节点
public mylistnode(t nodedata)
{
this.data = nodedata;
this.next = null;
}
}
}
下面是c# 泛型集合对这个模拟类的使用:
class program
{
static void main(string[] args)
{
mylist﹤string﹥ ml = new mylist﹤string﹥();
ml.addelement(xu);
ml.addelement(jin);
ml.addelement(lin);
ml.addelement(love);
ml.addelement(jasmine);
ml.insertatindex(4, fiercely);
ml.removeatindex(2);
ml.remove(lin);
foreach (string s in ml)
{
console.writeline(s);
}
}
}
