How to Convert string to JSON in C#

Make sure to import the `System.Text.Json` namespace in your application before calling the `JsonSerializer.Deserialize` method.
For example:
// Convert string to json in c# string jsonString = "{\"name\":\"Lucy\", \"age\":30, \"city\":\"New York\"}"; // Deserialize into a dynamic object var jsonObject = JsonConvert.DeserializeObject(jsonString);
This code deserializes a JSON string into a object, allowing you to access its properties directly.
// Access the values Console.WriteLine(jsonObject.name); // Output: Lucy Console.WriteLine(jsonObject.age); // Output: 30 Console.WriteLine(jsonObject.city); // Output: New York
You can also deserialize into a specific class or a strongly-typed object, like this:
public class Person { public string Name { get; set; } public int Age { get; set; } public string City { get; set; } }
// Deserialize into a specific class var person = JsonConvert.DeserializeObject<Person>(jsonString); Console.WriteLine(person.Name); // Output: Lucy Console.WriteLine(person.Age); // Output: 30 Console.WriteLine(person.City); // Output: New York
If you are using .NET Core or a later version of .NET, you can use the built-in System.Text.Json
library, which is part of the framework and does not require additional packages.
For example:
// c# convert string to json, deserialize into a dynamic object var jsonObject = JsonSerializer.Deserialize<JsonElement>(jsonString);
You can also deserialize into a strongly-typed object using System.Text.Json
:
For example:
// convert string to json c#, deserialize into a specific class Person person = JsonSerializer.Deserialize<Person>(jsonString);
If you're working on a project that is already using Newtonsoft.Json
or requires specific advanced features, stick with Json.NET
.
If you want to keep things simple and are working with .NET Core or later, System.Text.Json
may be the better choice.
