Convert JSON String to JSON Object c#

Convert JSON String to JSON Object c#

In C#, you can use the JsonConvert class from the Newtonsoft.Json namespace to convert a JSON string to a JSON object. Here's an example:

 using Newtonsoft.Json; // JSON string to be converted to a JSON object string jsonString = "{\"name\":\"John\", \"age\":30}"; // Convert the JSON string to a JSON object dynamic jsonObject = JsonConvert.DeserializeObject(jsonString); // Access properties of the JSON object string name = jsonObject.name; int age = jsonObject.age;

In this example, the JsonConvert.DeserializeObject method is used to convert the JSON string to a dynamic object, which can be used to access properties of the JSON object.

You can also use a strongly-typed object instead of dynamic by specifying the type as a generic parameter to DeserializeObject. For example:

 using Newtonsoft.Json; // Define a class to represent the JSON object class Person { public string Name { get; set; } public int Age { get; set; } } // JSON string to be converted to a JSON object string jsonString = "{\"name\":\"John\", \"age\":30}"; // Convert the JSON string to a Person object Person person = JsonConvert.DeserializeObject<Person>(jsonString); // Access properties of the Person object string name = person.Name; int age = person.Age;

In this example, the JsonConvert.DeserializeObject method is used to convert the JSON string to a Person object, which has Name and Age properties. The DeserializeObject method takes Person as a generic parameter, so the returned object is of type Person. You can then access the properties of the Person object using dot notation.
