How to Convert JSON Strings to C# Object Lists Using Newtonsoft JSON.NET?

Convert JSON Strings to C# Object Lists

JSON (JavaScript Object Notation) is a popular data format for representing structured data. It is often used for data exchange, configuration files, and other applications. C# provides powerful tools for working with JSON data, including the ability to convert JSON strings into objects.

Using Newtonsoft JSON.NET

Newtonsoft JSON.NET is a popular open-source library that makes it easy to work with JSON data in C#. It provides intuitive classes and methods for serializing and deserializing JSON data to and from various object types.

Convert a JSON String to a List of Objects

To convert a JSON string to a list of objects using Newtonsoft JSON.NET, follow these steps:

1. Install the Newtonsoft JSON.NET library from NuGet.
2. Define your object model that matches the structure of the JSON data.
3. Use the JsonConvert.DeserializeObject method to convert the JSON string to a list of your object type.

Here is an example:

// Define your object model
public class MatrixModel
{
    public string S1 { get; set; }
    public string S2 { get; set; }
    public string S3 { get; set; }
    public string S4 { get; set; }
    public string S5 { get; set; }
}

// Convert the JSON string to a list of objects
string json = "Your JSON string here";
var model = JsonConvert.DeserializeObject<List<MatrixModel>>(json);

Getting Only Specific Values

If you only want to get specific values from the JSON data, you can use the Select method to project the desired values into a new list.

For example, to get only the S1 and S2 values from the MatrixModel objects:

var values = model.Select(m => new { m.S1, m.S2 });

Online Tools

If you don't want to write code to convert JSON strings, you can use online tools such as json2csharp.com to generate C# object models from JSON data.
