New to C#. How to use google-admin-sdk (add users, add user to group a.s.o.)?

Question

Trying to get the hang of how to use google-admin-sdk in C# (got a possible job-opening)

I've managed to create code for creating users and adding a user to a group in Python 2.7 as commandline-tools.

But the employer asked med if I could do the same in C#. I think I would get the hang of it, but would appreciate some help on how to start. I have installed Visual Studio Express 2012 for Desktop and downloaded: google-admin-directory_v1-rev6-csharpp-1.4.0-beta.zip google-api-dotnet-client-1.4.0-beta-samples.zip google-api-dotnet-client-1.4.0-beta.zip

But I can't find any (for me understandble) samples.

Any one care to give me any good pointers? Would be very much appreciated. :) /Jonas

Edit : Adding my code so far!

namespace Bergstedts.ListUsers
{
    public class Program    
    {
        static void Main(string[] args)
        {
             // Display the header and initialize the sample.
            CommandLine.EnableExceptionHandling();
            CommandLine.DisplayGoogleSampleHeader("Lists all Users");

            // Register the authenticator.
            var provider = new NativeApplicationClient(GoogleAuthenticationServer.Description)
                {
                    ClientIdentifier = "my ID",
                    ClientSecret = "my secret"
                };

            var auth = new OAuth2Authenticator<NativeApplicationClient>(provider, GetAuthorization);

            // Create the service.
            var service = new DirectoryService(new BaseClientService.Initializer()
                {
                    Authenticator = auth,
                    ApplicationName = "List Users",

                });

            service.Users.List().Domain = "mydomain.com";
            Users results = service.Users.List().Execute();
            Console.WriteLine("Users:");
            foreach (User list in results.UsersValue)
            {
                Console.WriteLine("- " + list.Name);
            }
            Console.ReadKey();
        }

        private static IAuthorizationState GetAuthorization(NativeApplicationClient arg)
        {
            // Get the auth URL:
            IAuthorizationState state = new AuthorizationState(new[] { DirectoryService.Scopes.AdminDirectoryUser.GetStringValue() });
            state.Callback = new Uri(NativeApplicationClient.OutOfBandCallbackUrl);
            Uri authUri = arg.RequestUserAuthorization(state);

            // Request authorization from the user (by opening a browser window):
            Process.Start(authUri.ToString());
            Console.Write("  Authorization Code: ");
            string authCode = Console.ReadLine();
            Console.WriteLine();

            // Retrieve the access token by using the authorization code:
            return arg.ProcessUserAuthorization(authCode, state);
        }

    }
}

Edit : Found how to add the domain :

service.Users.List().Domain = "mydomain.com";

But I still get the same error message : An error has occured: Google.Apis.Requests.RequestError Bad Request [400] Errors [ Message[Bad Request] Location[ - ] Reason[badRequest] Domain[global] ]

Answer 1

This is fixed now! split the list().Execute() like this! Got help from @peleyal

var listReq = service.Users.List();
            listReq.Domain = domain;
        Users results = listReq.Execute();

Answer 2

This is another way to get users from a Domain (just a little different)

String serviceAccountEmail = "xxxxxxx@developer.gserviceaccount.com";
var certificate = new X509Certificate2(@"xxxxx.p12", "notasecret", X509KeyStorageFlags.Exportable);
ServiceAccountCredential credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
Scopes = new[] { DirectoryService.Scope.AdminDirectoryUser},
User = "your USER",  
}.FromCertificate(certificate));
var service = new DirectoryService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "name of your app",
});
var listReq = service.Users.List();
listReq.Domain = "your domain";
Users allUsers = listReq.Execute();
foreach(User myUser in allUsers.UsersValue){
    Console.WriteLine("*" + myUser.PrimaryEmail);
}
Console.ReadKey();
