以程序一执行程序便无响应,,怎么解决??

Question

也可以用try catch 抛出 e.tostring看看到底那一行的问题

Answer 1

按钮按下后程序便停止响应了,根本不能抛出Exception

Answer 2

private void buttonXP1_Click(object sender, System.EventArgs e)
        {
           
            using(DirectoryEntry root = new DirectoryEntry("WinNT:"))//有错误;
            {
                foreach(DirectoryEntry domain in root.Children)
                {
                    listBox1.Items.Add(">>>"+domain.Name);
                    foreach(DirectoryEntry pc in domain.Children)
                    {
                        if(pc.Name != "Schema")
                            listBox1.Items.Add("    "+pc.Name);
                    }
                }
            }
        }
