如何获得＆QUOT;公司＆QUOT;和＆QUOT;部＆QUOT;从Active Directory给予UserPrincipal对象？ [英] How to get "Company" and "Department" from Active Directory given a UserPrincipal object?

问题描述

这可能吗？ code样品将是很好的。

Is this possible? Code sample would be nice.

推荐答案

其实，问题是如何让两个属性的.NET 3.5 （System.DirectoryServices.AccountManagement。）UserPrincipal -object没有给出的UserPrincipalName 。

Actually, the question was how to get two of the properties for a .NET 3.5 (System.DirectoryServices.AccountManagement.)UserPrincipal-object not given a userPrincipalName.

下面怎么做，与延伸方法：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using System.DirectoryServices;
using System.DirectoryServices.AccountManagement;

namespace MyExtensions
{
    public static class AccountManagementExtensions
    {

        public static String GetProperty(this Principal principal, String property)
        {
            DirectoryEntry directoryEntry = principal.GetUnderlyingObject() as DirectoryEntry;
            if (directoryEntry.Properties.Contains(property))
                return directoryEntry.Properties[property].Value.ToString();
            else
                return String.Empty;
        }

        public static String GetCompany(this Principal principal)
        {
            return principal.GetProperty("company");
        }

        public static String GetDepartment(this Principal principal)
        {
            return principal.GetProperty("department");
        }

    }
}

以上code在大多数情况下工作（这是它会为标准文本/字符串单值Active Directory属性）。您需要修改code，并添加更多的错误处理code为您的环境。

The above code will work in most cases (that is it will work for standard Text/String Single-Value Active Directory attributes). You'll need to modify the code and add more error handling code for your environment.

您通过添加扩展类到你的项目中使用它，然后你可以这样做：

You use it by add the "Extension Class" to your project and then you can do this:

PrincipalContext domain = new PrincipalContext(ContextType.Domain);
UserPrincipal userPrincipal = UserPrincipal.FindByIdentity(domain, "youruser");
Console.WriteLine(userPrincipal.GetCompany());
Console.WriteLine(userPrincipal.GetDepartment());
Console.WriteLine(userPrincipal.GetProperty("userAccountControl"));

（顺便说一句，这将是对延伸属性一个伟大的使用 - 的太糟糕了它不会在C＃4任。）
