How Can I Save and Retrieve Serialized Objects in Files Using C#?

Persisting and Restoring Objects in Files using C#

Object serialization enables the storage and retrieval of an object's state. This requires the object's class to be marked with the [Serializable] attribute.

Let's illustrate with an example:

[Serializable]
public class MyClass
{
    public string MyProperty { get; set; }
}

MyClass myObject = new MyClass { MyProperty = "myValue" };

Saving myObject to a file can be done using these methods:

Binary Serialization:

WriteToBinaryFile<MyClass>("C:\myObject.bin", myObject);

XML Serialization:

WriteToXmlFile<MyClass>("C:\myObject.xml", myObject);

JSON Serialization:

WriteToJsonFile<MyClass>("C:\myObject.json", myObject);

These functions accept a file path and the object to serialize.

To retrieve the object:

Binary Serialization:

MyClass myObject = ReadFromBinaryFile<MyClass>("C:\myObject.bin");

XML Serialization:

MyClass myObject = ReadFromXmlFile<MyClass>("C:\myObject.xml");

JSON Serialization:

MyClass myObject = ReadFromJsonFile<MyClass>("C:\myObject.json");

These functions use the file path and return the deserialized object.

Crucially, the class must have the [Serializable] attribute for serialization and deserialization to work correctly.
