C# 自定义简单的IList

最近在学C#，就手动写了一个IList

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace WorkTwo
{
    /// <summary>
    /// 自定义List
    /// </summary>
    /// <typeparam name="T">泛型</typeparam>
    public class MyList<T>
    {
        //数据
        private T[] datas;

        /// <summary>
        /// 总条数
        /// </summary>
        public int Count { get; set; }
        /// <summary>
