线性表的实现方式
顺序表
顺序表是一种线性表的实现方式，它是用一组地址连续的存储单元依次存储线性表中的数据元素，使得逻辑上相邻的元素在物理上也相邻²³⁴。顺序表可以用数组来实现，它的优点是可以快速定位第几个元素，但是缺点是需要预先分配固定大小的空间，插入和删除操作需要移动大量元素¹⁵。顺序表在使用前需要初始化，初始化时需要确定起始位置、存储容量和长度

自定义一个IList
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace _01_LinearList
{interface IListDS<T>{int GetLength();void Clear();bool IsEmpty();void Add(T item);void Insert(T item, int index);T Delete(int index);T this[int index] { get; }//取表的元素T GetEle(int index);//定义一个索引器，获取元素int Locate(T value);//按值查找}
}定义SeqList实现IList
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace _01_LinearList
{class SeqList<T> : IListDS<T>{private T[] data;//用来存储数据private int count = 0;//表示存了多少个数据public T this[int index] =>GetEle(index);public SeqList(int size)//size就是最大容量{data = new T[size];count = 0;}public SeqList():this(10)//默认构造函数容量是10{}/// <summary>/// 添加值/// </summary>/// <param name="item"></param>public void Add(T item){if (count==data.Length)//当前数组已经存满{Console.WriteLine("当前顺序表已经存满，不允许再存入");}else{data[count] = item;count++;}}/// <summary>/// 清空/// </summary>public void Clear(){count = 0;}/// <summary>/// 删除元素/// </summary>/// <param name="index"></param>/// <returns></returns>public T Delete(int index){T temp = data[index];for (int i = index+1 ; i < count; i++){data[i - 1] = data[i];}count--;return temp;}/// <summary>/// 取元素/// </summary>/// <param name="index"></param>/// <returns></returns>public T GetEle(int index){if (index>=0&&index<=count-1)//索引存在{return data[index];}else{Console.WriteLine("索引不存在");return default(T); }}/// <summary>/// 取得数据的个数/// </summary>/// <returns></returns>public int GetLength(){return count;}/// <summary>/// 插入元素/// </summary>/// <param name="item"></param>/// <param name="index"></param>public void Insert(T item, int index){for (int i = count-1 ; i >= index; i--){data[i + 1] = data[i];}data[index] = item;count++;}public bool IsEmpty(){return count == 0;}/// <summary>/// 按值查找/// </summary>/// <param name="value"></param>/// <returns></returns>public int Locate(T value){for (int i = 0; i < count; i++){if (data[i].Equals(value)){return i;}}return -1;}}
}SeqList类（实现IListDS）
