            群组=（集团）（等待groupFetcher.ExecuteAsync（））;
            串[]用户id = userId.Split（，）;
            的foreach（在用户id字符串ID）
            {
                如果（ID！=）
                {
                    IUSER用户= client.Users.Where（U =＆GT; u.ObjectId ==标识）。.Exe​​cuteAsync（）Result.CurrentPage.ToArray（）第一（）;
                    如果（用户！= NULL）
                    {
                        //检查水灰比用户已位于present成组或不
                        IDirectoryObject userExists = group.Members.Where（U =＆GT; u.ObjectId == ID）.FirstOrDefault（）;
                        如果（userExists == NULL）
                        {
                            group.Members.Add（用户为DirectoryObject）;
                        }
                    }
                    其他
                        抛出新的异常（用户为空）;
                }
            }
            等待group.UpdateAsync（）;
            返回JSON（新{成功=真}）;
        }
        赶上（异常前）
        {
            ModelState.AddModelError（，我们粗野，处理您的请求，请联系以获取更多详细信息支持。）;
//错误处理code。
            返回PartialView（）;
        }
 

解决方案

大家好，我发现有什么问题，现在在这个。它是在旧的图形客户端库的bug。它在图形客户端库2.0解决了，所以请使用图形客户端库2.0或更高版本。

这是在这里你可以下载最新的图形客户端库的链接：

            IGroupFetcher groupFetcher = client.Groups.GetByObjectId(groupId);
            Group group = (Group)(await groupFetcher.ExecuteAsync());
            string[] userIds = userId.Split(',');
            foreach (string id in userIds)
            {
                if (id != "")
                {
                    IUser user = client.Users.Where(u => u.ObjectId == id).ExecuteAsync().Result.CurrentPage.ToArray().First();
                    if (user != null)
                    {
                        //check wather user aleady present into group or not
                        IDirectoryObject userExists = group.Members.Where(u => u.ObjectId == id).FirstOrDefault();
                        if (userExists == null)
                        {
                            group.Members.Add(user as DirectoryObject);
                        }
                    }
                    else
