C# - Get group info from Azure AD

Question

I'm using Azure AD login for an app to login with Microsoft credentials and get the groups (and their info) that the user is a part of.

With this line I'm able to get the logged in user: var userClaims = User.Identity as System.Security.Claims.ClaimsIdentity;

With this line I'm able to get the groups that the user is a part of: var groups = userClaims?.Claims.Where(claim => claim.Type == "groups").Select(c => c.Value);

Now I'm trying to integrate Microsoft.Graph so I can get the group's info (I only need the group's display name).

I'm using this code:

GraphServiceClient graphClient = new GraphServiceClient(new DelegateAuthenticationProvider((requestMessage) => {
requestMessage
.Headers
.Authorization = new AuthenticationHeaderValue("Bearer");
return Task.FromResult(0);}));

var group = graphClient.Groups[g].Request().GetAsync();

This doesn't work or I can't seem to figure out how to read properties of the group var.

Any simple way I can get the group's info?

Answer 1

As per the offical ms graph you can fetch the group display name by below

GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var groups = await graphClient.Groups
    .Request()
    .GetAsync();

Another work around is below:

var graphClient = GraphUtility.CreateGraphClient(accessToken);
var targetGroupCollection = await graphClient.Groups.Request()
                                    .Filter($"startsWith(displayName,'{groupName}')")
                                    .GetAsync();
