三、接口数据格式-2

一、List 转字符串

            List<string> list = new List<string>();
            list.Add("a");
            list.Add("b");
            list.Add("c");
            string s = string.Join(",", list.ToArray());
            MessageBox.Show(s);


a,b,c

        /// </summary>

        /// <param name="e"></param>
        private void Btn_DelParentNode(object sender, EventArgs e)
        {
            int[] rows = gridview_Parent.GetSelectedRows(); //获取GridView 选中的数据行信息
            if (rows.Length == 0)
            {
                MessageHelper.InfoMsg("请勾选一行记录。"); return;

                }
