自己测试如下：
using System;
using System.Collections.Generic;
using System.Text;
namespace testhasharrayds
{
public class outerrefinter
{
//外部类成员的类型可以是其内部类的类型，在此为内部类zxy,这样就可以从外部类访问内部类相关信息了
public zxy Out
{
get
{
//这是两种方式，一是通过引用变量，二是通过直接生成对象
//zxy z1 = new zxy("翟勋杨","陕西");
//return z1;
//属性一般与字段关联，在此属性直接与内部类关联起来，而且属性也可以与方法关联，属性是个很灵活的机制
return new zxy("翟勋杨", "陕西");
}
}
public class zxy //因为要在客户端代码访问此内部类zxy，它的访问修饰符定义为public
{
string name = string.Empty;
string addr = string.Empty;
public zxy(string _name,string _addr)
{
name = _name;
addr = _addr;
}
public string Name
{
get
{
return name;
}
}
public string Addr
{
get
{
return addr;
}
}
}
}
}
