我想使用 LDAP 在 Active Directory 中查询包含部分字符串的组，然后显示每个组中有多少用户。

为此，我正在研究LINQ to LDAP，因为我喜欢使用 LINQ 语法。要使用此方法进行查询，第二步是设置配置并进行查询：

var config = new LdapConfiguration();
config.ConfigureFactory("serverName.intranet");
using (var context = new DirectoryContext(config))
{
   context.Log = Console.Out;

   var user = context.Query<User>()
                .Where(u => u.FirstName == "Erwin")
                .FirstOrDefault();

   Console.WriteLine(user.Group);      
}

但第一步是定义模型。这就是我卡住的地方。我更愿意定义一个Group模型和一个User模型。这样我就可以查询并获得不同的Groups. Users另一个查询是找出这样一个组中有多少和什么类型。

不幸的是，我不知道也找不到如何使用 LINQ to LDAP 设置模型。现在我有一些随机属性：

using LinqToLdap.Mapping;
using System;
using System.Security.Principal;

[DirectorySchema("CN=Users")]
public class User
{
   [DirectoryAttribute("givenName")]
   public string FirstName { get; set; }

   [DirectoryAttribute("sn")]
   public string LastName { get; set; }

   [DirectoryAttribute("physicalDeliveryOfficeName")]
   public string Office { get; set; }
}

我得到了错误：

我怀疑那是因为我没有DirectorySchema以正确的方式定义。有人可以帮我设置 LINQ to LDAP 模型和查询吗？
