How to Save and Restore Serializable Objects Using Binary, XML, and JSON?

How to save and restore serializable objects to a file?

Saving object data between program executions is critical to maintaining state and sharing information. While various serialization formats exist, each with their own advantages and limitations, this reply provides solutions for handling binary, XML, and JSON serialization, comprehensively covering a variety of scenarios.

Binary serialization:

Use this method when dealing with objects that must be serialized/deserialized within the same application, without relying on external libraries or specific file formats.

XML serialization:

For scenarios where you need to share data across applications or platforms, consider using XML serialization. XML's text-based format makes it accessible to human readers and computer systems.

JSON serialization:

JSON serialization is great for storing and retrieving objects in text files. Its lightweight format and broad support make it easy to exchange and integrate data with other systems.

Achievement

The provided code snippets thoroughly clarify the functionality of each serialization method, allowing objects to be saved and restored seamlessly.

Example

To illustrate how to save an object as a binary file and restore it, consider the following example:

<code>// 将对象保存到文件。
WriteToBinaryFile("C:\path\to\file.bin", someObject);

// 从保存的文件中读取对象。
SomeClass restoredObject = ReadFromBinaryFile("C:\path\to\file.bin");</code>

This process ensures that the state of the object is preserved when restoring from the binary file, thus ensuring data integrity across executions.
