将LDAP数据映射到.NET类（LINQ）

为了构建LINQ到LDAP模型，我一直在使用几种不同的TUT。我已经差不多完成了，但是我在尝试绑定返回给类的数据时遇到了一些问题

我通过为类的属性（即数据库字段的实际名称）指定自定义属性来完成相反的部分

下面是该类的示例以及自定义属性（不包括

DirectorySchemaAttribute

和

DirectoryRootAttribute

实现…这些部分工作正常）：

谢谢， Chris

您知道“LINQ到Active Directory”吗？？请在上查看

这可能是一个很好的起点

不错。我看到的图坦卡蒙实际上是由发布这些课程的同一个人写的。现在拥有所有的代码是很有帮助的。在支持LDAP（而不是AD）方面仍然有一些困难，但您的帖子解决了我最初的问题。谢谢

    [DirectoryAttribute("cn")]

    [DirectoryAttribute("userpassword")]
    public string Password { get; set; }

    [DirectoryAttribute("C4-Parent")]
    public string Parent { get; set; }
}
