How to Effectively Convert JSON Strings to C# Objects?

Convert JSON string to C# object

When using JavaScriptSerializer to convert a JSON string to an object, you may encounter an issue where the target object remains undefined. To solve this problem, it is recommended to use Newtonsoft.Json library.

Solution

Newtonsoft.Json library provides a powerful solution for processing JSON data in C#. To convert JSON string to object:

<code class="language-c#">using Newtonsoft.Json;
...
var result = JsonConvert.DeserializeObject<T>(json);</code>

In the above code, T represents the object type corresponding to the JSON string. For example, if your JSON string is formatted as follows:

<code class="language-json">{
  "name": "John Doe",
  "age": 30
}</code>

You will define your object as:

<code class="language-c#">public class Person
{
  public string Name { get; set; }
  public int Age { get; set; }
}</code>

You can then convert the JSON string into an instance of the Person object using the following code:

<code class="language-c#">Person person = JsonConvert.DeserializeObject<Person>(json);</code>

This will create a Person object whose properties will be populated from a JSON string.
