C# 构建XML（简单示例）

C# 构建XML的简单示例：

var pars = new Dictionary<string, string> 
            {
                 {"url","https://www.baidu.com/"},
                {"name","jack"},
                {"sex","0"},
            };
            StringWriter sw = new StringWriter();
            XmlTextWriter xtw = new XmlTextWriter(sw);
            xtw.WriteStartElement("xml");
            foreach (var par in pars)
            {
                xtw.WriteElementString(par.Key, par.Value);
            }
            xtw.WriteEndElement();
            Console.WriteLine(sw.ToString());
