推荐答案

您好，在您的应用程序中遵循MVVM架构，将您的实体组织为类并使用绑定将对象绑定到UI。



要保存和检索，只需使用序列化保存对象，而不是保存UI。您可以通过反序列化来检索这些对象。



研究以下内容，

1. MVVM架构

2 。对象序列化和DeSerialization

3. WPF中的DataBinding

4. ObservableCollections

Hi, follow MVVM architecture in your application, organize your entities as classes and use binding to bind objects to the UI.

To Save and retrieve, instead of saving the UI, just save the objects using serialization. You can retrieve those objects by deserialization.

Study about the followings,
1. MVVM architecture
2. Object Serialization and DeSerialization
3. DataBinding in WPF
4. ObservableCollections
