How to Deserialize JSON Text into C# Objects?

Deserialize JSON Text into C# Objects

Deserializing JSON text into C# objects can be accomplished through a few simple steps.

For the provided JSON response:

{
  "err_code": "0",
  "org": "CGK",
  "des": "SIN",
  "flight_date": "20120719",
  "schedule": [
    ["W2-888", "20120719", "20120719", "1200", "1600", "03h00m", "737-200", "0", [["K", "9"], ["F", "9"], ["L", "9"], ["M", "9"], ["N", "9"], ["P", "9"], ["C", "9"], ["O", "9"]]],
    ["W2-999", "20120719", "20120719", "1800", "2000", "01h00m", "MD-83", "0", [["K", "9"], ["L", "9"], ["M", "9"], ["N", "9"]]]
  ]
}

1. Visual Studio IDE: Click Edit > Paste Special > Paste JSON as Classes, which will generate C# classes for the JSON structure.
2. NuGet: Install Newtonsoft.Json package for JSON serialization/deserialization functionality.
3. Code: In your project, deserialize the JSON string into an object using the below code:

Rootobject r = Newtonsoft.Json.JsonConvert.DeserializeObject<Rootobject>(jsonString);

Replace "jsonString" with the variable containing the JSON text. Rename "Rootobject" with a more descriptive class name.

4. Object Instance: The "r" variable now contains an instance of the C# object created from the deserialized JSON. You can access its properties to retrieve data, such as:

string errCode = r.err_code;
string org = r.org;

Follow these steps to effortlessly convert JSON text into C# objects, enabling you to work with structured data in your applications.
