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());
