How to call this REST - Post resource in C#

I need to make the following call in REST. Can anyone provide a C# sample on how to do this ? From: https://docs.microsoft.com/en-us/azure/active-directory/active-directory-protocols-oauth-code

RestSharp really did make creating these rest calls easier (thanks Soren).

string token = await GetAccessToken();

var client = new RestSharp.RestClient("https://login.microsoftonline.com/common/oauth2/v2.0");
var request = new RestRequest("token");

request.AddParameter("grant_type","authorization_code");
request.AddParameter("client_id", "edd7c078-...f5d4979c7f4e");
request.AddParameter("code", "Ma49210e1-5332-a5dc-4005-70411bf85fbe");

request.AddParameter("redirect_uri", "https://localhost:44333");
request.AddParameter("client_secret", "qZqxfjca6xg0scsNP67KATy");

request.Method = Method.POST;
request.AddHeader("Authorization", "Bearer " + token);

var response = client.Execute(request);
