反序列化（path为xml文件路径）

public static List<T> GetXmlData(string path)          {              if (File.Exists(path))              {                  XmlSerializer xml = new XmlSerializer(typeof(List<T>));                  using (StreamReader w = new StreamReader(path))                  {                      List<T> list = xml.Deserialize(w) as List<T>;                      return list;                  }              }              return new List<T>();          }

序列化，如果xml文件存在，则被覆盖

public static void Serialize(List<T> list,string path)          {              XmlSerializer lizer = new XmlSerializer(typeof(List<T>));                            using (System.IO.StreamWriter writer = new System.IO.StreamWriter(path))              {                  System.Xml.Serialization.XmlSerializer xs = new System.Xml.Serialization.XmlSerializer(typeof(List<T>));                  xs.Serialize(writer, list);                  writer.Close();              }          }
