How to Serialize and Deserialize Objects to/from Files in C#?

C# Object File Saving and Restoration

Saving the object to the computer requires that the object be serializable. This means that the object must be able to be converted into a format that can be written to a file, and then later read back into memory and converted back into an object. The following functions perform serialization and deserialization:

Binary serialization

<code class="language-csharp">public static void WriteToBinaryFile<T>(string filePath, T objectToWrite, bool append = false)
public static T ReadFromBinaryFile<T>(string filePath)</code>

XML serialization

<code class="language-csharp">public static void WriteToXmlFile<T>(string filePath, T objectToWrite, bool append = false) where T : new()
public static T ReadFromXmlFile<T>(string filePath) where T : new()</code>

JSON serialization

<code class="language-csharp">public static void WriteToJsonFile<T>(string filePath, T objectToWrite, bool append = false) where T : new()
public static T ReadFromJsonFile<T>(string filePath) where T : new()</code>

Example

Save the contents of the object1 variable to a file using binary serialization:

<code class="language-csharp">WriteToBinaryFile<SomeClass>("C:\someClass.txt", object1);</code>

Read the file contents back into a variable:

<code class="language-csharp">SomeClass object1 = ReadFromBinaryFile<SomeClass>("C:\someClass.txt");</code>
