如何获得“公司"和“部门"从 Active Directory 给定 UserPrincipal 对

问题描述

这可能吗?代码示例会很好.

Is this possible? Code sample would be nice.

推荐答案

实际上，问题是如何获取 .NET 3.5 (System.DirectoryServices.AccountManagement.)UserPrincipal 的两个属性-object 没有给定 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.

这里如何使用扩展方法:>

Here how to do that with an extension method:

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");
        }

    }
}

以上代码适用于大多数情况(即适用于标准文本/字符串单值 Active Directory 属性).您需要修改代码并为您的环境添加更多错误处理代码.

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.

您可以通过将扩展类"添加到您的项目中来使用它，然后您可以这样做:

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；这对扩展属性非常有用 - 太糟糕了，它也不会出现在 C# 4 中.)

(BTW; this would have been a great use for Extension Properties - too bad it won't be in C# 4 either.)
