Cognito and ASP.NET C# problem

Question

I have been trying to get the session and the details of the current user after he has successfully logged in into the system as seen in the code below. However, I am not very sure how to get the session and details of the current user, the one i saw was through Javascript. Is there any way to use ASP.NET C# code to get those details? 

 

Here is my code :

 

         const string PoolID = "id";
         const string ClientID = "id";
         static Amazon.RegionEndpoint Region = Amazon.RegionEndpoint.USEast1;
         protected void Page_Load(object sender, EventArgs e)
         {
            string username = "1";
            string password = "2";
            string email = "3";
            SignInUser(username,password);
        }
        static async Task<int> SignInUser(string username, string password)
        {
            AmazonCognitoIdentityProviderClient provider = new AmazonCognitoIdentityProviderClient(new Amazon.Runtime.AnonymousAWSCredentials(), Region);

            CognitoUserPool userPool = new CognitoUserPool(PoolID, ClientID, provider);

            CognitoUser user = new CognitoUser(username, ClientID, userPool, provider);

            InitiateSrpAuthRequest authRequest = new InitiateSrpAuthRequest()
            {
                Password = password
            };

            AuthFlowResponse authResponse = null;
            try
            {
                authResponse = await user.StartWithSrpAuthAsync(authRequest).ConfigureAwait(false);
            }

            catch (Exception ex)
            {
                System.Diagnostics.Debug.WriteLine("Logon Failed: {0}\n", ex.Message);
                return 0;
            }

            GetUserRequest getUserRequest = new GetUserRequest();
            getUserRequest.AccessToken = authResponse.AuthenticationResult.AccessToken;

            System.Diagnostics.Debug.WriteLine(authResponse.AuthenticationResult.AccessToken);
            System.Diagnostics.Debug.WriteLine("Logon Successful");
            return 1;
        }

 Any help will be appreciated. Thank You.
