C#系列课程——Object定义

代码入下：

using System;class obj_Sample_Class{    public int i = 10;}class MainClass{    static void Main()    {        object a;        a = 100;        Console.WriteLine(a);        Console.WriteLine(a.GetType());        Console.WriteLine(a.ToString());        a = new obj_Sample_Class();        obj_Sample_Class classRef;        classRef = (obj_Sample_Class)a;        Console.WriteLine(classRef.i);    }}
