  FileInfo file = new FileInfo(lvControl.SelectedItems[0].Text);
                    TreeNode node = new TreeNode(file.Name); //文件名作为节点文本
                    node.Tag = file.FullName; //完整路径存放在Tag属性里面这样node.tag.tostring（）与打开文件对话框的dlg.filename为什么不能一样的使用？怎么改？下为完整代码,此为listview项目双击事件 public void listview1_ItemActivate(object sender, EventArgs e)
        {
     
            string sfileName = "";
