Question

我想阻止共享点（例如：成员）中的一组用户使用csom访问“共享文档”。但是，当我执行我的代码时，它不起作用（我上面提到的组中的帐户仍然可以在我的站点中访问。有我的代码：

ClientContext context = new ClientContext("https://example.com/sites/Litware");
            SecureString password = new SecureString();
            foreach (char c in "abcd".ToCharArray()) password.AppendChar(c);
            context.Credentials = new SharePointOnlineCredentials("example@example.onmicrosoft.com", password);
            var web = context.Web;
            context.Load(web);
            context.ExecuteQuery();
            var memGroup = web.SiteGroups.GetByName("Member");
            context.Load(memGroup);            
            var users = memGroup.Users;
            context.Load(users);
            context.ExecuteQuery();
            foreach (var user in users)
            {
                Principal principal = web.EnsureUser(user.LoginName);
                var folder = web.GetFolderByServerRelativeUrl("/Shared Documents");
                var roleDef = context.Site.RootWeb.RoleDefinitions.GetByType(RoleType.None);                               
                var roleBindings = new RoleDefinitionBindingCollection(context) { roleDef };
                folder.ListItemAllFields.BreakRoleInheritance(true, false);
                folder.ListItemAllFields.RoleAssignments.Add(principal, roleBindings);
            }

那么，我在哪里弄错了以及如何解决呢？

请参考以下代码：
