数据字典Dictionary存放键值对

Posted 2020-10-26 青红造了个白

1.     方法思路：

使用数据字典【Dictionary<string, string>】，声明一个list集合，将“XML子节点名称”、“节点值”以键【节点名称】值【节点值】对的形式存入此集合，然后将此集合作为参数传入封装的公共方法中即可；

2.     公共方法：

 public static string AssembleXML(Dictionary<string,string> list)
        {
            try
            {
                string strXML = "";
                foreach (KeyValuePair<string, string> de in list)
                {
                    strXML += "<" + de.Key + ">" + de.Value + "</" + de.Key + ">";
                }
                return strXML;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message, "组装XML时出现错误：", MessageBoxButtons.OK, MessageBoxIcon.Error);
                return "0";
            }          
        }

3.      对公共方法的调用：

static void Main(string[] args)
        {
            string strXML交换 = "";
            Dictionary<string, string> list = new Dictionary<string, string>();
            list.Add("姓名","张三");    //xml节点、节点值
            list.Add("年龄", "20");         
            string strResult = AssembleXML(list);
            if (strResult=="0")
            {
                MessageBox.Show("组装xml出现错误！");
            }
            else
            {
                strXML交换 = @"<?xml version=‘1.0‘ encoding=‘GBK‘?><ROWSET><ROW>" + strResult + "</ROW></ROWSET>";             
            }            
            Console.WriteLine(strXML交换);
            Console.ReadKey();             
        }
