.Net C# XML XmlSerializer 总结

      //数据类节点

        [Serializable]
        [XmlRoot("SQB_HEAD")]
        //输出节点带命名空间
        //[XmlRoot(ElementName = "SQB_HEAD", Namespace = "http://www.w3.org/2001/XMLSchema-instance")]
        public class SQB_HEAD
        {
            public string WORK_NO { get; set; }
            public string GATEPASS { get; set; }
            public string GATEPASS_NO { get; set; }


            //输出头节点SQB_BODYList和子节点SQB_BODY,List<SQB_BODY> 必须指定Type，SQB_BODY[]数组无需指定Type属性
            //[XmlArray("SQB_BODYList"),XmlArrayItem("SQB_BODY", Type = typeof(SQB_BODY))]
            //直接输出子节点SQB_BODY
            [XmlElement(ElementName = "SQB_BODY", Type = typeof(SQB_BODY))]             
            public List<SQB_BODY> ArrSQB_BODY { get; set; }


        }

        //XmlSerializer代码

        #region XML序列化


        XmlSerializerNamespaces xmlnsEmpty = new XmlSerializerNamespaces();
        //xmlnsEmpty.Add("", "");//去除默认命名空间 xmlns:xsd和xmlns:xsi
        //以下两步会直接将命名空间加在XML指定的Root节点上(SQB_HEAD)，如需分别加，应分开序列化节点
        xmlnsEmpty.Add("", "http://www.w3.org/2001/XMLSchema-instance");//添加命名空间，子数据无需加前缀
        xmlnsEmpty.Add("tcs", "http://www.chinaport.gov.cn/tcs/v2");//添加命名空间，并将子数据全部添加上tcs：前缀
        XmlSerializer xmlser = new XmlSerializer(_type);
