How can I access a specific value from a JSON response in C# .net?-CodePudding

I'm trying to make a POST on an API so I can get a bearer token.

Example:

var client = new RestClient("https://api");

var request = new RestRequest();

request.AddHeader("Content-Type", "application/x-www-form-urlencoded");
request.AddParameter("client_id", "X");
request.AddParameter("grant_type", "client_credentials");
request.AddParameter("client_secret", "X");

var response = client.Post(request);
Console.WriteLine(response.Content);

The response is this JSON:

{ 
  "access_token": "aisodjaisjd4123",
  "token_type": "Bearer",
  "expires_in": 3599
}

How can I store that aisodjaisjd4123 into a variable?

CodePudding user response：

You can serialise this json to a class object. And then access_token member will have token value.

You can use NewtonSoft.Json to deserialise the string to object. You can search it in Nuget Package manager.

Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);
    public class Root
    {
        public string access_token { get; set; }
        public string token_type { get; set; }
        public int expires_in { get; set; }
     }

And please ignore the indentation, I have typed from phone.
