老师布置一任务    要求是用listbox  button 空间做一个sort排序   
                  具体内容 "
                  1.添加两个button 两个listbox  
                  重新命名button为 Read 和Sort,并且Read添加一个openfiledialog 控件 ，使其可以调用本地磁盘下的text文件，
                  2.将text文件显示在listBox1里，通过普通的排序（比如选择，冒泡，插入等等），将listBox1的内容重新排序，
                  点击Sort，排序好的内容在Listbox2里显示.

小弟是菜鸟，希望大虾能过帮个小忙 ，在线等 谢谢了啊!!!

}
这是  “ 源 ”  不知道怎么回事 运行 出错

好了 船上去了 是那个错误提示 程序可以编译运行

谢谢啊~~~~

问题还是没有解决啊！！！ 问个菜鸟问题啊 用Button的事件  openfiledialog ，打开了一个窗口，并且可以选中一个文本文件，可是却怎么也不能把这个文本文件的内容添加到listBox里去，那么 listBox 到底能不能接受并显示文本的内容？不能的话 我应该选用那种控件呢？

读取text文本文档，想把文档里面的内容都读进去，
                foreach (string s in dlg.FileNames)
                {
                    this.listBox1.Items.Add(s);
                }
这个只是把Items度进去了 ，不是我想要的啊~~~
