推荐答案

如果您使用 .NET 3.5 及更高版本并谈论 Active Directory，那么您应该查看 System.DirectoryServices.AccountManagement (SDS.AM) 命名空间.在此处阅读所有相关信息:

If you're on .NET 3.5 and up and talking about Active Directory, then you should check out the System.DirectoryServices.AccountManagement (S.DS.AM) namespace. Read all about it here:

• 在 .NET Framework 3.5 中管理目录安全主体莉>
• 有关 System.DirectoryServices.AccountManagement 的 MSDN 文档

基本上，您可以定义域上下文并轻松找到 AD 中的用户和/或组:

Basically, you can define a domain context and easily find users and/or groups in AD:

// set up domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

// find a user
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, "SomeUserName");

if(user != null)
{
   // do something here....     
   var usersSid = user.Sid;

   // not sure what you mean by "username" - the "DisplayName" ? The "SAMAccountName"??
   var username = user.DisplayName;
   var userSamAccountName = user.SamAccountName;
}

新的 S.DS.AM 使在 AD 中与用户和组一起玩变得非常容易！

The new S.DS.AM makes it really easy to play around with users and groups in AD!

更新:如果您需要遍历域的所有用户 - 试试这个:

Update: if you need to loop through all the users of a domain - try this:

您可以使用 PrincipalSearcher 和query-by-example"主体来进行搜索:

You can use a PrincipalSearcher and a "query-by-example" principal to do your searching:

// create your domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

// define a "query-by-example" principal - here, we search for a UserPrincipal 
UserPrincipal qbeUser = new UserPrincipal(ctx);

// create your principal searcher passing in the QBE principal    
PrincipalSearcher srch = new PrincipalSearcher(qbeUser);

// find all matches
foreach(var found in srch.FindAll())
{
    UserPrincipal user = found as UserPrincipal;

    if(user != null)
    {
       // do whatever here 
       var usersSid = user.Sid;

       // not sure what you mean by "username" - the "DisplayName" ? 
       var username = user.DisplayName;
       var userSamAccountName = user.SamAccountName;
    }
}

更新 #2:如果您不能(或不想)使用 S.DS.AM 方法 - 这是最简单的方法，对于 Active目录，到目前为止 - 那么你需要回退到 System.DirectoryServices 类和方法:

Update #2: if you can't (or don't want to) use the S.DS.AM approach - which is the easiest, for Active Directory, by far - then you need to fall back to the System.DirectoryServices classes and methods:

// define the root of your search
DirectoryEntry root = new DirectoryEntry("LDAP://dc=YourCompany,dc=com");

// set up DirectorySearcher  
DirectorySearcher srch = new DirectorySearcher(root);
srch.Filter = "(objectCategory=Person)";
srch.SearchScope = SearchScope.Subtree;

// define properties to load
srch.PropertiesToLoad.Add("objectSid");
srch.PropertiesToLoad.Add("displayName");

// search the directory
foreach(SearchResult result in srch.FindAll())
{
   // grab the data - if present
   if(result.Properties["objectSid"] != null && result.Properties["objectSid"].Count > 1)
   {
       var sid = result.Properties["objectSid"][0];
   }

   if(result.Properties["displayName"] != null && result.Properties["displayName"].Count > 0)
   {
       var userName = result.Properties["displayName"][0].ToString();
   }
}
