我对 UserPrincipal 类进行扩展以检索我需要的一些缺失的属性：

[DirectoryObjectClass("user")]
[DirectoryRdnPrefix("CN")]
class UserPrincipalExt : UserPrincipal
{
    public UserPrincipalExt(PrincipalContext context)
        : base(context)
    {
    }

    [DirectoryProperty("department")]
    public string Department

        }
    }

    [DirectoryProperty("c")]
    public string CountryAbbreviation
    {
        get
        {
            if (ExtensionGet("c").Length != 1)
                return null;
            return (string)ExtensionGet("c")[0];
        }
        set
        {
            this.ExtensionSet("c", …
