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:

<code class="language-csharp">[Serializable]
public class MyClass
{
    public string MyProperty { get; set; }
}

MyClass myObject = new MyClass { MyProperty = "myValue" };</code>

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

Binary Serialization:

<code class="language-csharp">WriteToBinaryFile<MyClass>("C:\myObject.bin", myObject);</code>

XML Serialization:

<code class="language-csharp">WriteToXmlFile<MyClass>("C:\myObject.xml", myObject);</code>

JSON Serialization:

<code class="language-csharp">WriteToJsonFile<MyClass>("C:\myObject.json", myObject);</code>

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

To retrieve the object:

Binary Serialization:

<code class="language-csharp">MyClass myObject = ReadFromBinaryFile<MyClass>("C:\myObject.bin");</code>

XML Serialization:

<code class="language-csharp">MyClass myObject = ReadFromXmlFile<MyClass>("C:\myObject.xml");</code>

JSON Serialization:

<code class="language-csharp">MyClass myObject = ReadFromJsonFile<MyClass>("C:\myObject.json");</code>

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.
