Serialize and deserialize JSON in C#
JSON serialization in C#
JSON serialization is the process of converting C# objects into JSON format.Using Newtonsoft.Json (JSON.NET):
To serialize an object to JSON, you can use the JsonConvert.SerializeObject() method. This method takes an object as input and returns a JSON string as output.
In this example, a Person object is serialized to JSON using JsonConvert.SerializeObject.
JSON deserialization in C#
JSON deserialization is the process of converting JSON data back into C# objects.Using Newtonsoft.Json (JSON.NET):
In this example, the JSON data is deserialized into a Person object using JsonConvert.DeserializeObject.
Serializing and deserializing JSON is a common task in many C# applications. By understanding how to use the Newtonsoft.Json library, you can easily serialize and deserialize JSON to and from C# objects.
You can customize the serialization behavior by using attributes from the System.Text.Json.Serialization namespace (available in C# 8.0 and later) or JSON.NET attributes from the Newtonsoft.Json namespace.Using System.Text.Json:
In this example, JsonPropertyName attributes are used to specify custom JSON property names.
Handling Null Values
Both libraries handle null values during serialization and deserialization.Using Newtonsoft.Json:
The NullValueHandling setting can be used to control how null values are handled during serialization.
You should handle exceptions that may occur during deserialization, such as JsonSerializationException.
JSON Serialization in ASP.NET Web APIs
In ASP.NET Web APIs, you can return objects directly from controller actions, and they are automatically serialized to JSON.
Serializing and deserializing JSON in C# involves converting C# objects to JSON format and vice versa. Libraries like JSON.NET (Newtonsoft.Json) or the built-in System.Text.Json provide easy-to-use methods for this purpose, enabling data interchange between C# objects and JSON data sources such as web APIs and configuration files.
