Get List of Users from AGOL using C# .Net

[ParminderDhaliwal]

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;

Looks like you are not awaiting this call 🙂

Thanks PreetiMaske for your response.

I added await to the call but I am still getting the "'You do not have permissions to access this resource or perform this operation."

What version of ArcGIS Enterprise are you using? 

I think the user is how you are getting the credential, the call for the Users is fine.

That is a obsolete method for getting credentials, you should really be using the OAuth pattern.

Also as a general comment you are not using an async calls the way they are designed, should call await not have .Wait at the end of a call

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.

@ParminderDhaliwal 

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

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<Root?>(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<string> 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; }

}
