小弟求助！！
如何索引一个类中的多个字类啊？？

比如：

class A
{
class B:A
{
string Name;
}

class C:A
{
string Name;
}

class D:A
{
string Name;
}
class E:A ..........

}

如上所述
public partial class Form1 : Form
{
int i = 0;
private void button1_Click(object sender, EventArgs e)
{
if(i<3)
{

//想实现点一下button1让，label1.Text = B.Name;
//再点一下button1让，label1.Text = C.Name;
//再点一下button1让，label1.Text = D.Name;
//再点一下button1让，label1.Text = E.Name;
//..........
//再点一下button1让，label1.Text = B.Name;
//再点一下button1让，label1.Text = C.Name;
//........

//如此循环。。。
i++;
}
else
{
i=0;
}
i++;

}
}

[解决办法]

C# code

    public class Program    {        public class A : Program        {            public string Name = "A";        }        public class B : Program        {            public string Name = "B";        }        public class C : Program        {            public string Name = "C";        }        public static void Main()        {            for (int i = 0; i < 3; i++)            {                Type type = typeof(Program).GetNestedTypes()[i];                Console.WriteLine(type.GetField("Name").GetValue(type.GetConstructors()[0].Invoke(null)).ToString());            }            //输出            //A            //B            //C        }    }
