https://www.c-sharpcorner.com/article/asp-net-mvc-oauth-2-0-rest-web-api-authorization-using-database-first-approach/

when i give clientid and clientsecret from postman its generating the access token, so same scenario i want to call it from mvc c# code.

i was trying below code to access api code(to get access token), its not working
string clientId = "...-C179-4F9B-9F3F-EBB0A0116778";
string clientSecret = "....-1086-4CE2-92ED-12B130F8B664";
string credentials = String.Format("{0}:{1}", clientId, clientSecret);
var client = new HttpClient
{
BaseAddress = new Uri("http://localhost:65392/token")
};
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.UTF8.GetBytes(credentials)));
//Prepare Request Body
Liststring, string>> requestData = new Liststring, string>>();
requestData.Add(new KeyValuePair<string, string>("grant_type", "client_credentials"));
FormUrlEncodedContent requestBody = new FormUrlEncodedContent(requestData);
//Request Token
var request = await client.PostAsync("http://localhost:65392/token", requestBody);
var response = await request.Content.ReadAsStringAsync();
