        //在WPF或者Silverlight中，ObservableCollection是一个集合，它可以用于绑定UI元素，当集合中的数据发生改变时，UI会自动更新。ObservableCollection实现了INotifyCollectionChanged接口，这使得当集合改变时，它可以通知UI进行更新。

        //然而，ObservableCollection本身不支持序列化。如果你需要序列化ObservableCollection，你需要自己实现一些逻辑。


        //以下是一种可能的方法：

        //使用DataContractSerializer进行序列化。

        public static string Serialize<T>(ObservableCollection<T> collection)
        {
            DataContractSerializer serializer = new DataContractSerializer(typeof(List<T>));
            using (MemoryStream ms = new MemoryStream())
            {
                serializer.WriteObject(ms, collection.ToList());
                ms.Position = 0;
                using (StreamReader reader = new StreamReader(ms))
                {
                    return reader.ReadToEnd();
                }
            }
        }

        public static ObservableCollection<T> Deserialize<T>(string xml)
        {
            DataContractSerializer serializer = new DataContractSerializer(typeof(List<T>));
            using (Stream ms = new MemoryStream())
            {
                using (StreamWriter writer = new StreamWriter(ms))
                {
                    writer.Write(xml);
                    writer.Flush();
                    ms.Position = 0;
                    List<T> list = (List<T>)serializer.ReadObject(ms);
                    return new ObservableCollection<T>(list);
                }
            }
        }

        //使用XmlSerializer进行序列化。

        public static string XSerialize<T>(ObservableCollection<T> collection)
        {
            XmlSerializer serializer = new XmlSerializer(typeof(List<T>));
            using (StringWriter textWriter = new StringWriter())
            {
                serializer.Serialize(textWriter, collection.ToList());
                return textWriter.ToString();
            }
        }

        public static ObservableCollection<T> XDeserialize<T>(string xml)
        {
            XmlSerializer serializer = new XmlSerializer(typeof(List<T>));
            using (StringReader textReader = new StringReader(xml))
            {
                List<T> list = (List<T>)serializer.Deserialize(textReader);
                return new ObservableCollection<T>(list);
            }
        }

        /*
        以上两种方法都是将ObservableCollection先转换为List，然后进行序列化，反序列化的时候，再将List转换回ObservableCollection。

        需要注意的是，这两种方法都需要类型T是可序列化的，即类型T上面需要有[DataContract] 或者[XmlType]这样的Attribute。

        另外，如果你的ObservableCollection中含有非基础类型，那么这些类型也需要是可序列化的，否则会抛出异常。

        以上就是ObservableCollection的序列化方法，希望对你有所帮助。*/
