//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。

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。*/
