Question

我一直在尝试从SP网站获取所有用户。我有代码工作，以获取组和组名称，但当我尝试从组中访问用户时，我得到一个例外。我在使用它之前初始化了所有组件，我认为这是CSOM地狱的经典案例。但即使经过很多改变，我也无法解决它。任何投入都表示赞赏..

您必须在CSOM中加载属性。

string SiteUrl = "The Website";

        System.Uri oUri = new System.Uri(SiteUrl);

        using (ClientContext oClientContext = new ClientContext(SiteUrl))
        {
            //Replace it with your user id for SharePoint Online
            string UserName = XXXXXXX;
            //Replace it with your password
            string Password = XXXXXXXXXXXXXX;
            oClientContext.Credentials = new NetworkCredential(UserName, Password);
            Console.WriteLine(oClientContext.Web.SiteGroups);
            oClientContext.Load(oClientContext.Web, w => w.SiteGroups.Include(o => o.Users.Include(l => l.LoginName), o => o.Title, o => o.Description, o => o.OwnerTitle));
            try
            {
                oClientContext.ExecuteQuery();
                Console.WriteLine("Connected");
            }
            catch (Exception e)
            {

                Console.WriteLine("The error is \n" + e.Message);
                Console.WriteLine("The source is \n" + e.Source);
                Console.WriteLine("The Stack Trace is \n" + e.StackTrace);
            }
            GroupCollection oSiteCollectionGroups = oClientContext.Web.SiteGroups;              
            Console.WriteLine("List of groups in the site collection");
            Console.WriteLine("-------------------------------------");
            Console.WriteLine(oSiteCollectionGroups.AreItemsAvailable);
            foreach (Group oGroup in oSiteCollectionGroups)
            {
                Console.WriteLine(oGroup.Title);
            }
            Console.WriteLine("<<<<<<<<<<===================|End of Groups|========================>>>>>>>");                
            Console.WriteLine("List of users in the first group of site-collection");
            Console.WriteLine("-------------------------------------------------------");              

            for (int i = 1; i < oSiteCollectionGroups.Count; i++)
            {
                Console.WriteLine("Items Available =>" + oSiteCollectionGroups[i].Users.AreItemsAvailable);
                Console.WriteLine(oSiteCollectionGroups[i].Description);
                Console.WriteLine(oSiteCollectionGroups[i].LoginName);
                Console.WriteLine(oSiteCollectionGroups[i].Title);
                Console.WriteLine("Owner Title =>" + oSiteCollectionGroups[i].OwnerTitle);                    
                try
                {
                    foreach (User oUser in oSiteCollectionGroups[i].Users)
                    {
                        Console.WriteLine(oUser.Title);
                        Console.WriteLine("n");
                    }

                }
                catch (Exception e)
                {

                    Console.WriteLine("Exception Occured");
                    Console.WriteLine("The error is \n" + e.Message);
                    Console.WriteLine("The source is \n" + e.Source);
                    Console.WriteLine("The Stack Trace is \n" + e.StackTrace);
                }
            }
            Console.WriteLine("<<<<<<<<<<===================|End of Memebers|========================>>>>>>>");
            Console.ReadLine();

        }
