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.

C# Convert String to Json Object

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:

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string City { get; set; }
}

// jsonserializer deserialize string
var person = JsonConvert.DeserializeObject<Person>(jsonString); // convert string to object c#
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.

C# String to JsonElement

To convert a C# string to a JsonElement, you can use the System.Text.Json library, which is a part of .NET Core and .NET 5+.

A JsonElement represents a read-only, typed value that you can access directly without needing to deserialize the JSON into an object.

For example, how you can convert a c# string to a JsonElement:

// 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.

To convert a string to a JObject using Newtonsoft.Json (also known as Json.NET) in C#, you can use the JObject.Parse method. This method parses a JSON-formatted string and returns a JObject, which is a part of the Newtonsoft.Json library that allows for dynamic handling of JSON data.

For example, string to JsonObject C#

// Sample JSON string
string jsonString = "{\"Name\":\"John\", \"Age\":30}";

// Convert string to JObject
JObject jsonObject = JObject.Parse(jsonString);

// Output the JObject
Console.WriteLine("JObject: " + jsonObject);

// Access individual properties from the JObject
string name = jsonObject["Name"].ToString();
int age = (int)jsonObject["Age"];

// Display values
Console.WriteLine($"Name: {name}, Age: {age}");

If you want to keep things simple and are working with .NET Core or later, System.Text.Json may be the better choice.
