谁来帮我看一下《C#2.0程序设计教程》中一个例题的错误呀
//程序清单P14_1.cs：

错误1“P14_1.Assemble <T> ”不会实现接口成员“System.Collections.IEnumerable.GetEnumerator()”。“P14_1.Assemble <T> .GetEnumerator()”或者是静态、非公共的，或者有错误的返回类型。D:\My Documents\Visual Studio 2005\Projects\ConsoleApplication2\Program.cs2918ConsoleApplication2
我是个C#半新手，今天我照着书上的这个程序编写了一段代码，也是这个错误，开始我以为是自己哪个程序中其它地方写错了，结果把书上的这段代码原封不动的运行也出现上面一样的错误，谁帮我看看是什么地方不对呀？？？？？？？谢谢了
[解决办法]
把
IEnumerator <T> IEnumerable <T> .GetEnumerator()
{
return GetEnumerator();
}
中的..return GetEnumerator();改成
return m_list.GetEnumerator(); 看看..不知道行不行
[解决办法]
using System.Collections;
