Microsoft Graph C# SDK: How to use AppendSegmentToRequestUrl with microsoft.graph.user

Question

I am trying to get all users and their group memberships, using the GraphServiceClient in C#
I have tried this endpoint: https://graph.microsoft.com/v1.0/groups/{GroupId}/members/microsoft.graph.user?$select=displayName,id,mail&$expand=memberOf($select=id,displayName)
The request works fine with Postman. However not able to make it work with C#. This is the Code I tried

var membersRequestUrl = _graphClient.Groups["GroupId"]
                .Members
                .AppendSegmentToRequestUrl("microsoft.graph.user?$count=true");
var requestBuilder = new GroupMembersCollectionWithReferencesRequestBuilder(membersRequestUrl, _graphClient);
var memberRequest = requestBuilder
                .Request()
                .Header("ConsistencyLevel", "eventual")
                .Select("displayName,id,mail")
                .Expand("memberOf($select=id,displayName)");
Console.WriteLine(memberRequest.GetHttpRequestMessage().RequestUri);
var members = await memberRequest.GetAsync();
 Console.WriteLine(JsonConvert.SerializeObject(members));

In line #10, I see the correct URL has been generated. But I do not get the proper response at line #12.
The response I got is:

{
  "DeletedDateTime": null,
  "Id": "{User-Id}",
  "ODataType": null,
  "AdditionalData": {
    "displayName": {
      "ValueKind": 3
    },
    "mail": {
      "ValueKind": 3
    },
    "memberOf": {
      "ValueKind": 2
    }
  }
}

As I can see, the properties are correct, but the values are missing. Event the User-Id is correct.

Hi dear @Ahsan Habib I tested your code and it seems to be no problem, I can return all the results. Below is my complete code, you can have a try.

using System;  
using Microsoft.Identity.Client;  
using Microsoft.Graph.Auth;  
using Microsoft.Graph;  
using System.Collections.Generic;  
using Newtonsoft.Json;  
  
namespace test  
  
{  
    class Program  
    {  
  
        static async System.Threading.Tasks.Task Main(string[] args)  
  
         
        {  
            IConfidentialClientApplication app;  
            app = ConfidentialClientApplicationBuilder.Create("{client id}")  
                    .WithClientSecret("{Client Secret}")  
                    .WithAuthority(new Uri("https://login.microsoftonline.com/{tenant id}"))  
                    .Build();  
  
            AuthenticationResult result = null;  
            string[] scopes = new string[] { "https://graph.microsoft.com/.default" };  
            result = await app.AcquireTokenForClient(scopes).ExecuteAsync();  
            string accesstoken = result.AccessToken;  
  
            //Console.WriteLine(accesstoken);  
  
            ClientCredentialProvider authProvider = new ClientCredentialProvider(app);    
  
            GraphServiceClient graphClient = new GraphServiceClient(authProvider);  
  
            var membersRequestUrl = graphClient.Groups["{group id}"]  
                   .Members  
                   .AppendSegmentToRequestUrl("microsoft.graph.user?$count=true");  
            var requestBuilder = new GroupMembersCollectionWithReferencesRequestBuilder(membersRequestUrl, graphClient);  
            var memberRequest = requestBuilder  
                            .Request()  
                            .Header("ConsistencyLevel", "eventual")  
                            .Select("displayName,id,mail")  
                            .Expand("memberOf($select=id,displayName)");  
            Console.WriteLine(memberRequest.GetHttpRequestMessage().RequestUri);  
            var members = await memberRequest.GetAsync();  
            Console.WriteLine(JsonConvert.SerializeObject(members));  
  
        }  
    }  
}
