Get List of Users from AGOL using C# .Net

Question

I am trying to get a list of AGOL users in my Organization, by passing the Admin User Credentials in a C# program. I would like to know how I can pass the credential to the portalTask. I am using Maps SDK for .Net version 200.1.

var userName = "adminUser";
var password = "adminPassword";
var portalURL = "https://myOrg.maps.arcgis.com";
string tokenURL = portalURL + "/sharing/rest/generateToken";

var credentialTask = AuthenticationManager.Current.GenerateCredentialAsync(new Uri(tokenURL), userName, password);
credentialTask.Wait();
TokenCredential cred = credentialTask.Result;

var poralTask = ArcGISPortal.CreateAsync(new Uri(portalURL));poralTask.Wait();
ArcGISPortal portal = poralTask.Result;

var userTask = portal.FindUsersAsync(new PortalQueryParameters("username=A*"));
var users = userTask.Result;

I ended up implementing the following solution using the REST endpoints. var userName = "adminUser";var password = "adminPassword";var portalURL = "https://myOrg.maps.arcgis.com"; string tokenURL = portalURL + "/sharing/rest/generateToken"; var credentialTask = AuthenticationManager.Current.GenerateCredentialAsync(new Uri(tokenURL), userName, password);credentialTask.Wait();TokenCredential cred = credentialTask.Result; var client = new HttpClient(); int start = 1;int number = 10;while (start != -1){ string url = string.Format("{0}/sharing/rest/portals/self/users/search?start={1}&num={2}&f=json&token={3}", portalURL, start, number, cred.Token); var request = new HttpRequestMessage(HttpMethod.Post, url); var response = await client.SendAsync(request); response.EnsureSuccessStatusCode(); var jsonResponse = response.Content.ReadAsStringAsync().Result; Root? root = JsonConvert.DeserializeObject(jsonResponse); foreach (Result user in root.Results) { Console.WriteLine(user.FullName); } start = root.NextStart;} Here are my Root and Result classes to store the json results from the call.public class Result { public string UserName { get; set; } public object UDN { get; set; } public string ID { get; set; } public string FullName { get; set; } public List Categories { get; set; } public string EmailStatus { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public object PreferredView { get; set; } public object Description { get; set; } public string Email { get; set; } public string UserType { get; set; } public object IDPUsername { get; set; } public object FavGroupId { get; set; } public object LastLogin { get; set; } public bool MFAEnabled { get; set; } public bool ValidateUserProfile { get; set; } public int StorageUsage { get; set; } public int StorageQuota { get; set; } public string OrgId { get; set; } public string Role { get; set; } public string Level { get; set; } public string UserLicenseTypeId { get; set; } public bool Disabled { get; set; } public List

Esri has a pretty in depth sample on setting up OAuth Authentication in Mobile/AGOL located here: Access services with OAuth 2.0   This is probably the best place to start as it requires setup in AGOL in addition to the code.

I do not think that you can use the methods that just take a user name and password to generate a credential from AGOL anymore (I may be incorrect, but that is my understanding).  We have switched to using OAuth in all our applications

Thanks for your response JoeHershman. 
I am using ArcGIS Online (maps.arcgis.com). I agree my code is not correct that is why it is not working. Can you please supply any code sample to create a credential object using OAuth and attach it to portalTask or userTask.
