获取用户在Active Directory目录 [英] Get list of user in Active Directory
问题描述
我写这需要得到用户的列表从指定域的应用程序。我能得到现在的用户,但它的方式来减缓我怎么能做到这一点更快特别是在较大的领域?
I am writing an application that needs to get a list of users from a specified domain. I can get the users now, but it is way to slow how can I do this faster especially on larger domains?
using (PrincipalContext pc = new PrincipalContext(ContextType.Domain, domain))
{
UserPrincipal userPrincipal = new UserPrincipal(pc);
PrincipalSearcher search = new PrincipalSearcher(userPrincipal);
PrincipalSearchResult<Principal> results = search.FindAll();
foreach (var principals in results.Partition(20))
{
IDictionary<string, string> users = new Dictionary<string, string>(20);
foreach (UserPrincipal principal in principals.Cast<UserPrincipal>())
{
users.Add(principal.SamAccountName, principal.DisplayName);
}
yield return users;
}
}
基本上在外层foreach循环我得到的IEnumerable的一个IEnumerable>。我这样做,这样我就可以尝试逐步加载一些的时间和他们显示给用户,而其余仍在加载,但一旦我打的内环,我收到了几分钟的挂起。
Basically in the outer foreach loop I am getting an IEnumerable of IEnumerable>. I did that so I could try to incrementally load a few at a time and display them to the user while the rest are still loading, but once I hit that inner loop I get a several minute hang.
我试图让域\用户名格式的用户名以及我还没有想出如何做到既。
I am trying to get the users name in domain\username format as well which I haven't figured out how to do either.
推荐答案
试试这个。它应该工作得更快。
Try this. It should work faster.
using System.DirectoryServices;
string[] RetProps = new string[] { "SamAccountName", "DisplayName" };
//IDictionary<string, string> users = new Dictionary<string, string>();
List<string[]> users = new List<string[]>();
foreach (SearchResult User in GetAllUsers("YourDomain", RetProps))
{
DirectoryEntry DE = User.GetDirectoryEntry();
try
{
users.Add(new string[]{DE.Properties["SamAccountName"][0].ToString(), DE.Properties["DisplayName"][0].ToString()});
}
catch
{
}
}
internal static SearchResultCollection GetAllUsers(string DomainName, string[] Properties)
{
DirectoryEntry DE = new DirectoryEntry("LDAP://" + DomainName);
string Filter = "(&(objectCategory=organizationalPerson)(objectClass=User))";
DirectorySearcher DS = new DirectorySearcher(DE);
DS.PageSize = 10000;
DS.SizeLimit = 10000;
DS.SearchScope = SearchScope.Subtree;
DS.PropertiesToLoad.AddRange(Properties); DS.Filter = Filter;
SearchResultCollection RetObjects = DS.FindAll();
return RetObjects;
}
}
}
