我使用.net库的System.DirectoryServices.AccountManagement部分的接口到ActiveDirectory中。

I am using the System.DirectoryServices.AccountManagement part of the .Net library to interface into ActiveDirectory.

有叫GetMembers（）在GroupPrincipal对象和过滤结果，我现在有UserPrincipal对象的集合

Having called GetMembers() on a GroupPrincipal object and filter the results, I now have a collection of UserPrincipal objects

GroupPrincipal myGroup;  // population of this object omitted here 

foreach (UserPrincipal user in myGroup.GetMembers(false).OfType<UserPrincipal>())
{
    Console.WriteLine(user.SamAccountName);
}

以上code样品将打印出像TestUser1用户名。我需要这些比较列表从DOMAIN TestUser1格式的另一个应用程序来了。

The above code sample will print out usernames like "TestUser1". I need to compare these to a list coming from another application in "DOMAINTestUser1" format.

我如何获得域部分从UserPrincipal对象？

How do I get the "DOMAIN" part from the UserPrincipal object?

我不能只追加一个已知域名，因为涉及到多个域，我需要区分DOMAIN1 TestUser1和DOMAIN2 TestUser2。

I can't just append a known domain name as there are multiple domains involved and I need to differentiate DOMAIN1TestUser1 and DOMAIN2TestUser2.

推荐答案

您有两个选择，我能想到的。

You have two choices that I can think of.

解析，或采取一切，是对， name@fully.qualified.domain.name 的权利; 使用的System.DirectoryServices 命名空间。 Parse, or take everything that is on, the right of name@fully.qualified.domain.name; Use the System.DirectoryServices namespace.

我不知道的 UserPrincipal ，我也不关于 GroupPrincipal 。在另一方面，我知道的工作方式才达到你想要什么。

I don't know about UserPrincipal, neither do I about GroupPrincipal. On the other hand, I know of a working way to achive to what you want.

[TestCase("LDAP://fully.qualified.domain.name", "TestUser1")] 
public void GetNetBiosName(string ldapUrl, string login)
    string netBiosName = null;
    string foundLogin = null;

    using (DirectoryEntry root = new DirectoryEntry(ldapUrl))
        Using (DirectorySearcher searcher = new DirectorySearcher(root) {
            searcher.SearchScope = SearchScope.Subtree;
            searcher.PropertiesToLoad.Add("sAMAccountName");
            searcher.Filter = string.Format("(&(objectClass=user)(sAMAccountName={0}))", login);

            SearchResult result = null;

            try {
                result = searcher.FindOne();

                if (result == null) 
                    if (string.Equals(login, result.GetDirectoryEntry().Properties("sAMAccountName").Value)) 
                        foundLogin = result.GetDirectoryEntry().Properties("sAMAccountName").Value
            } finally {
                searcher.Dispose();
                root.Dispose();
                if (result != null) result = null;
            }
        }

    if (!string.IsNullOrEmpty(foundLogin)) 
        using (DirectoryEntry root = new DirectoryEntry(ldapUrl.Insert(7, "CN=Partitions,CN=Configuration,DC=").Replace(".", ",DC=")) 
            Using DirectorySearcher searcher = new DirectorySearcher(root)
                searcher.Filter = "nETBIOSName=*";
                searcher.PropertiesToLoad.Add("cn");

                SearchResultCollection results = null;

                try {
                    results = searcher.FindAll();

                    if (results != null && results.Count > 0 && results[0] != null) {
                        ResultPropertyValueCollection values = results[0].Properties("cn");
                        netBiosName = rpvc[0].ToString();
                } finally {
                    searcher.Dispose();
                    root.Dispose();

                    if (results != null) {
                        results.Dispose();
                        results = null;
                    }
                }
            }

    Assert.AreEqual("INTRATESTUSER1", string.Concat(netBiosName, "", foundLogin).ToUpperInvariant())
}
