线性表 C#实现

概念

　　主要参考C#数据结构一书

　　线性表和顺序表

代码

线性表接口

using System;
using System.Collections.Generic;
using System.Text;

namespace CSharpDemo
{
    public interface ILinearList<T>
    {
        int GetLength();

        void Clear();

        bool IsEmpty();

        void Append(T item);

        void Insert(T item, int i);

        void Delete(int i);

        T GetElement(int i);

        int Locate(T item);
    }
}

 顺序表

using System;
using System.Collections.Generic;
using System.Text;

namespace CSharpDemo
{
    /// <summary>
    /// 顺序表实现
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class SequenceList<T>:ILinearList<T>
    {
        #region Field and Property
        
        private int maxsize;
        private T[] data;
        private int last;

        public int MaxSize
        {
            get
            {
                return this.maxsize;
            }
            set
            {
                this.maxsize = value;
            }
        }

        #endregion
