Question

I want a sample application in c#.net which can create users in Office 365 using Microsoft API .

I wish to do it in code, not using Powershell.

You can use the Microsoft Graph API - Create User:

Register a Native Client App on Azure AD, assign the "Microsoft Graph" > "Read and Write Directory Data" permission.

            string authority = "https://login.windows.net/yourdomain.onmicrosoft.com";

            string clientId = "{app_client_id}";

            Uri redirectUri = new Uri("http://localhost");

            string resourceUrl = "https://graph.microsoft.com";

            HttpClient client = new HttpClient();

            AuthenticationContext authenticationContext = new AuthenticationContext(authority, false);

            AuthenticationResult authenticationResult = authenticationContext.AcquireToken(resourceUrl,
                clientId, redirectUri, PromptBehavior.Always);

            client.DefaultRequestHeaders.Add("Authorization", "Bearer " + authenticationResult.AccessToken);

            string content = @"{
                'accountEnabled': true,
                'displayName': 'testuser',
                'mailNickname': 'test',
                'passwordProfile': {
                    'forceChangePasswordNextSignIn': true,
                    'password': 'pass@wd12345'
                },
                'userPrincipalName': 'testuser@yourdomain.onmicrosoft.com'
            }";

            var httpContent = new StringContent(content, Encoding.GetEncoding("utf-8"), "application/json");

            var response = client.PostAsync("https://graph.microsoft.com/v1.0/users", httpContent).Result;

            Console.WriteLine(response.Content.ReadAsStringAsync().Result);
