无法获取部门名称、经理名称并仅在 Microsoft Graph 中获取有限的用户响应 API C#

Question

I am using below code to get all the users from Active Directory:

     static async Task Main(string[] args)

    {
        int Flag = 0;


        //  var message = await result;

        try
        {


            var tenantId = "XXXXX.onmicrosoft.com";
            string searchCriteria = "";
            string searchString = "";

            string tokenUrl = $"https://login.microsoftonline.com/XXXXX.onmicrosoft.com/oauth2/v2.0/token";
            var tokenRequest = new HttpRequestMessage(HttpMethod.Post, tokenUrl);

            //I am Using client_credentials as It is mostly recommended
            tokenRequest.Content = new FormUrlEncodedContent(new System.Collections.Generic.Dictionary<string, string>
            {
                ["grant_type"] = "client_credentials",
                ["client_id"] = "XXX9",
                ["client_secret"] = "XXXXXX",
                ["scope"] = "https://graph.microsoft.com/.default"
            });

            dynamic json;
            AccessTokenClass results = new AccessTokenClass();


            //New Block For Accessing Data from Microsoft Graph Rest API
            HttpClient client = new HttpClient();
            var tokenResponse = await client.SendAsync(tokenRequest);
            json = await tokenResponse.Content.ReadAsStringAsync();
            results = JsonConvert.DeserializeObject<AccessTokenClass>(json);

            HttpClient _client = new HttpClient();

            string urlGraphUsers = "https://graph.microsoft.com/v1.0/users?$top=999";
            // odata_nextlink
            do
            {
                HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, string.Format(urlGraphUsers));
                //Passing Token For this Request
                request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", results.access_token);
                //unable to get department name in response

                HttpResponseMessage response = await _client.SendAsync(request);
                string responseBody = await response.Content.ReadAsStringAsync();

                dynamic objGpraphUserList = JsonConvert.DeserializeObject<dynamic>(await response.Content.ReadAsStringAsync());


                var apiResponse = await response.Content.ReadAsStringAsync();


                var data = JsonConvert.DeserializeObject<jsonModel>(apiResponse);
                urlGraphUsers = data.odata_nextLink;




                foreach (valueModel r in data.value.ToList())

                {
                   //Print all the fields ,but unable to get Reporting Manager name and Department 
                   Console.WriteLine(r.displayName);
                    Console.WriteLine(r.mail);
                }

                if (Flag == 0)
                {
                    await context.PostAsync($"No Search results found! Please Try again");

                }
            }
            while (urlGraphUsers != null);

        }


        catch
        {
            await context.PostAsync($"Unknown Exception Occurred. Unable to search results!");
            context.Done(true);
        }

        Console.WriteLine(Flag);
        Console.WriteLine("Flag");
        context.Done(true);

    }


     public class jsonModel
    {
        public string @odata_context { get; set; }
        public string @odata_nextLink { get; set; }
        public List<valueModel> value { get; set; }
    }
    public class valueModel
    {
        public List<string> businessPhones { get; set; }
        public string displayName { get; set; }
        public string givenName { get; set; }
        public string jobTitle { get; set; }
        public string mail { get; set; }
        public string mobilePhone { get; set; }
        public string officeLocation { get; set; }
        public string preferredLanguage { get; set; }
        public string surname { get; set; }
        public string userPrincipalName { get; set; }
        public string id { get; set; }
    }

I am unable to get Department name in response.Obviously something like r.departmentName doesn't work here.

And i am only getting 100 users,even though i use odata.nextlink while loop. This do while loop runs only one time and shows only 100 users. Value of data.odata_nextLink; in the first loop itself is null.

How to fetch all the users using pagination and also department name and manager name or directReports. Please help, as i am beginner.

Answer 1

As far as I know, the user just has property department but not departmentName , you can refer to this document .

In you code, when you do the "deserialize" operation, you need to let it know the odata_nextLink refers to @odata.nextLink field in json response. So please modify your code as below:

public class jsonModel
{
    [JsonProperty("@odata.context")]
    public string odata_context { get; set; }

    [JsonProperty("@odata.nextLink")]
    public string odata_nextLink { get; set; }

    public List<valueModel> value { get; set; }
}

After that, your code will work fine, the data.odata_nextLink will not be null.

Hope it helps~

I recommend to leverage Microsoft .NET SDKs to avoid reinventing the wheel. This should work using Microsoft.Graph.Beta nuget package . This due MS Graph V1 not supporting user manager expands .

 private static async Task PrintUsersWithManager()
        {
            var app = ConfidentialClientApplicationBuilder.Create(clientId)
                .WithAuthority(AzureCloudInstance.AzurePublic, tenantId)
                .WithClientSecret(clientSecret)
                .Build();

            var token = await app.AcquireTokenForClient(new[] { ".default" }).ExecuteAsync();

            var graphServiceClient = new GraphServiceClient(
                new DelegateAuthenticationProvider(
                    async (message) =>
                    {
                        var result = await app.AcquireTokenForClient(new[] { ".default" }).ExecuteAsync();
                        message.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", result.AccessToken);
                    }
                    )
                );

            var page = await graphServiceClient.Users.Request()
                .Expand(u => u.Manager)
                .GetAsync();

            var users = new List<User>();

            users.AddRange(page);

            while (page.NextPageRequest != null)
            {
                page = await page.NextPageRequest
                    .Expand(u => u.Manager)
                    .GetAsync();

                users.AddRange(page);
            }

            foreach (var item in users)
            {
                Console.WriteLine(JsonConvert.SerializeObject(new
                {
                    item.Id,
                    item.DisplayName,
                    item.Department,
                    Manager = item.Manager != null ? new
                    {
                        item.Manager.Id,
                        displayName = ((User)item.Manager).DisplayName
                    } : null
                }));
            }
        }
