我觉得你的问题在这里

i think u problem is here

if (tvLinks.Nodes[I].Text == IconLocation.Host.ToString())
    {
        tvLinks.Nodes[I].Nodes.Add(srInput.ReadLine());
        break;
    }
    else if (I == tvLinks.Nodes.Count - 1)
    {
        tvLinks.Nodes.Add(IconLocation.Host).Nodes.Add(srInput.ReadLine());
        break;
    }

您最确定的是，每个

You most asure that u are parsing well the info in ur text file en every

tvLinks.Nodes[I].Text

都建议您对文本文件中的信息进行很好的解析:P

a debug is recommended :P
