listview 获取选中行的数据

//如果不加listview.SelectedIndices.Count>0判断，将导致获取listview.Items[]索引超界的异常

if (lv_backup_file.SelectedIndices != null && lv_backup_file.SelectedIndices.Count>0)

show_restore_info.Text += backup_file;

}

//设置listview的点击事件,命名为lv_selected

//以下方法经过验证

private void lv_selected(object sender, EventArgs e)

{

//清空textbox显示

if (show_restore_inzfo.Lines.Count() > 1)

show_restore_info.Text = null;

}

//开始选择备份文件.注意无法多选.
