C# 组装XML传给webserver+XML 返回获取多个xml，根据多个XML 返回dataset类型

大致流程介绍：

传值给 webserver+XML ，得到webserver+XML多个返回值，组装成dataset形式返回

首先创建所需要的类型
DataSet ds = new DataSet();  //表集合
DataTable dt = new DataTable;               //表

dt.Columns.Add("ID"); 添加表的列名

dt.Columns.Add("Name"); 添加表的列名

DataRow dr = dt.NewRow(); //表行
try
{

//组装xml 传给webser+XMl需要的入参
string xml_PESelfReg_value = Assemble_XML.XML_BARCODE(PatientID);

   public static string XML_BARCODE(string PEADM)
         {
             XDocument doc = new XDocument(
                new XDeclaration("1.0", "utf-8", "yes"),///XML的声明，包括版本，编码，xml文件是否独立
                 new XElement("Request",new XElement("PEADM",""+PEADM+""))
                              //根节点
                  );

             return doc.ToString();

         }
