如何使用ASP.NET核心中活动目录组的成员填充下拉列表？

using System.DirectoryServices.AccountManagement;
using Microsoft.AspNetCore.Mvc.Rendering;

public List<SelectListItem> GetGroupMembers(string groupName)
{
    List<SelectListItem> members = new List<SelectListItem>();

    using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
    {
        GroupPrincipal group = GroupPrincipal.FindByIdentity(context, groupName);

        if (group != null)
        {
            foreach (Principal principal in group.GetMembers())
            {
                members.Add(new SelectListItem
                {
                    Text = principal.Name,
                    Value = principal.SamAccountName
                });
            }
        }
    }

    return members;
}

public IActionResult Index()
{
    YourViewModel viewModel = new YourViewModel();
    viewModel.Members = GetGroupMembers("YourGroupName");

    return View(viewModel);
}

@model YourViewModel

@Html.DropDownListFor(m => m.SelectedMember, Model.Members, "Select a member")
