I use this code for find users in AD

  SearchResultCollection results = null;
                System.DirectoryServices.DirectoryEntry entry = new DirectoryEntry("LDAP://...");
                DirectorySearcher adSearcher = new DirectorySearcher(entry);
                adSearcher.SearchScope = SearchScope.Subtree;
               adSearcher.Filter = "(&(objectClass=user)(sAMAccountName=" + userName + "))";

                results = adSearcher.FindAll();
        catch (Exception e)


and add a Children

 using (DirectoryEntry ou = new DirectoryEntry("LDAP://Domainname"))

                DirectoryEntry user = ou.Children.Add("CN=" + txtuser.Text, "user");
                int NORMAL_ACCOUNT = 0x200;
                int PWD_NOTREQD = 0x20;
                user.Properties["sAMAccountName"].Value = txtuser.Text;
                user.Properties["userAccountControl"].Value = NORMAL_ACCOUNT | PWD_NOTREQD;
                user.Properties["displayName"].Value = txtname.Text;
                user.Properties["description"].Value = txtnote.Text;
                user.Invoke("SetPassword", new object[] { txtpass.Text });
