索引器与数组类定义练习

using System;
class ArrClass { //没有索引器的类
    private readonly string name;
    public ArrClass(string name) {
        this.name = name;
    }
    public string Name {
        get {
            return name;
        }
    }
}
class IndexClass { //带索引器的类
    private string[] name = new string[10];
    public string this[int index] {
        get {
            return name[index];
        }
        set {
            name[index] = value;
        }
    }
}
class test {
    static void Main() {
        //数组类的使用
        ArrClass[] a = new ArrClass[10];
        a[0] = new ArrClass("张三");
        a[1] = new ArrClass("李四");
        Console.WriteLine("a[0]" + a[0].Name);
        Console.WriteLine("a[1]" + a[1].Name);
        //索引器的使用
        IndexClass b = new IndexClass();
        b[0] = "王五";
        b[1] = "赵六";
        Console.WriteLine("b[0]" + b[0]);
        Console.WriteLine("b[1]" + b[1]);
        Console.ReadKey();
