停止在MVC视图中显示Active Directory组的某些成员

Question

我试图停止Active Directory在视图中显示属于组测试的某些帐户。例如，我不想显示SamAccountName =“ Doman Users”

C＃

public ActionResult Index(string username)
    {
        username = "test";
        string[] output = null;
        // username = sssftappdev;
        using (var ctx = new PrincipalContext(ContextType.Domain))
        using (var user = UserPrincipal.FindByIdentity(ctx, username))
        {
            if (user != null)
            {
                output = user.GetGroups()
                    .Select(x => x.SamAccountName) 
                    .ToArray(); 
              }

        }
        return View(output);
    }

 <table id="tbldirectory" class="table table-striped table-bordered table-hover">                <thead>
                <tr>
                    <th></th>
                    <th>
                        @Html.Label("Group Name")
                    </th>
                </tr>
            </thead>
            <tbody>
                @foreach (var output in Model)
                {
                    <tr>
                        <th>
                            @Html.ActionLink("View", "Index", "ActiveDirectoryMember", new { id = output }, new { @class = "btn btn-xs btn-primary" }) |                                
                        </th>
                        <th>@output</th>
                    </tr>
                }
            </tbody>
        </table>
