Answer 1

If you're using .NET 3.5 or newer, you can use a PrincipalSearcher and a "query-by-example" principal to do your searching:

// create your domain context
string container = "OU=DBG,OU=THINCLIENT,OU=NPS,OU=services,DC=YourDomain,DC=com";
using (PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "YourDomain", container))
{
   // define a "query-by-example" principal - here, we search for 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())
   {
       // do whatever here - "found" is of type "Principal" - it could be user, group, computer.....          
   }
}

If you haven't already - absolutely read the MSDN article Managing Directory Security Principals in the .NET Framework 3.5 which shows nicely how to make the best use of the new features in System.DirectoryServices.AccountManagement . Or see the MSDN documentation on the System.DirectoryServices.AccountManagement namespace.

You'll need to add a reference to the System.DirectoryServices.AccountManagement assembly in your references, and you'll need a line like this:

using System.DirectoryServices.AccountManagement;

at the top of your code-behind file for this to work.

You can specify any of the properties on the UserPrincipal and use those as "query-by-example" for your PrincipalSearcher .

You can use System.DirectoryServices Namespace.

 DirectoryEntry scope = new   DirectoryEntry("LDAP://OU=DBG,OU=THINCLIENT,OU=NPS,OU=services,DC=YourDomain,DC=com");

 string filter = "(&(objectClass=user)(objectCategory=user))";
 string[] attrs = new string[]{"samaccountname","whencreated"};
 DirectorySearcher searcher = new  DirectorySearcher(scope,filter,attrs);

 foreach(SearchResult result in searcher.FindAll())
 {
     //result.Properties["attribute"][0].ToString();
 }
