如何使用 Microsoft Graph API 获取所有组的用户名？

Question

I want to read all member names of all groups using Graph API

My Method

var unternehmen = await graphManager
    .Client
    .Groups
    .Request()
    .Expand("members")
    .GetAsync();

foreach (var gruppe in unternehmen)
{
    Debug.Log("  " + gruppe.Id + " " + gruppe.DisplayName);

    foreach (var member in gruppe.Members)
    {
         Debug.Log(member.Id);
    }         
}

Response

Only Member ID's and all Group Names

What I need is all names of all groups. How can I get those?

Answer 1

You need to caste the members to Microsoft.Graph.User first because not all members are users.

GET https://graph.microsoft.com/v1.0/groups/{id}/members/microsoft.graph.user

C# code:

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

foreach (var gruppe in groups)
{
    Console.WriteLine($"{gruppe.Id}, {gruppe.DisplayName}");

    // another method to get members
    // var members = await graphClient.Groups[gruppe.Id].Members.Request().GetAsync();
    
    var members = gruppe.Members;
    var userMembers = members.Where(m => m.ODataType == "#microsoft.graph.user").Cast<User>();
    foreach (User user in userMembers)
    {
        Console.WriteLine($"{user.Id}, {user.DisplayName}");
    }

}
