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",""},

             };

             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());
