if you are getting json by calling HttpClient. you can try this var json = await response.Content.ReadAsStringAsync(); JToken jtoken = JToken.Parse(json); var SelectedToken = jtoken.SelectToken(keyData[1]); string tokenValue = SelectedToken.Value(); if (tokenValue.StartsWith( "pf-" )) { } keyData[1] => this will give you value of the json( in key value)
