XML相关

读取Xml文件

　　这里的xml地址可能有问题，不太懂，我用的绝对地址。这里的xml里有&符号会报错(“An error occurred while parsing EntityName”)。

XmlDocument xmldoc = new XmlDocument();
FileStream fs = new FileStream(@"..\XMLFile2.xml", FileMode.Open, FileAccess.Read);
xmldoc.Load(fs);
return xmldoc;

Xml反序列化成对象

要反序列化的xml，这里要得到Recommendations

构建Recommendations对象　　

[XmlRoot(Namespace = "urn:ebay:apis:eBLBaseComponents")]
    public class Recommendations
    {
        public int CategoryID { get; set; }

        [XmlElement]
        public List<NameRecommendation> NameRecommendation { get; set; }
    }　　

public class NameRecommendation
    {
        public string  Name { get; set; }

        public ValidationRules ValidationRules { get; set; }

        [XmlElement]
        public List<ValueRecommendation> ValueRecommendation { get; set; }
    }

public class ValidationRules
    {
        public string ValueType { get; set; }

        public int MinValues { get; set; }

        public int MaxValues { get; set; }

        public string SelectionMode { get; set; }

        public string VariationSpecifics { get; set; }
    }

public class ValueRecommendation
    {
        [XmlElement]
        public string  Value { get; set; }

        public ValidationRules ValidationRules { get; set; }
    }

反序列化代码　　

public static T Deserialize<T>(XmlDocument response, string NodeName)
            {
                XmlNodeList NameRecommendationList = response.GetElementsByTagName(NodeName);

                string xml = NameRecommendationList[0].OuterXml;

                XmlSerializer serializer = new XmlSerializer(typeof(T));

                #region 将XML 转换成流
                byte[] byteData = null;
                byteData = Encoding.ASCII.GetBytes(xml);
                Stream stream = new MemoryStream(byteData);
                #endregion

                //将流转化为想要的对象
                T test = (T)serializer.Deserialize(stream);

                return test;
            }
