C#教程之数据字典Dictionary存放键值对

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";
            }          
        }
