相信这个类，它的成员大家都熟记于心，做为.NET开发人员对于它的了解一定是最深的。再重复一下：
Equals 对象间比较
Finalize 资源回收
GetHashCode 生成一个与对象值相对应的数字以支持哈希表的使用
ToString 描述类的实例的可读文本字符串
using System;
class Point
{
private int x,y;
public Point(int x, int y)
{
this.x = x;
this.y = y;
}
public override bool Equals(object obj)
{
if(obj == null || obj.GetType() != this.GetType() ) return false;
Point other = (Point)obj;
return (this.x == other.x)&&(this.y == other.y);
}
public override int GetHashCode()
{
return x^y;
}
public override String ToString()
{
return String.Format(“{0},{1}”,x,y);
}
public Point Copy()
{
return (Pont) this.MemberwisClone();
}
}
Equals(Object)指定object 是否等于当前object
[s]Equals(Object, Object)
