扫描不同域下的AD账户进行删除

 public ResultModel GetEntryOneToDel(string sAMAccountName)
        {
            bool del=false;
            ResultModel result = new ResultModel();
            foreach (var ldap in LDAPStore)
            {
                ADHelper.DomainName = ldap.DomainName;
                ADHelper.LDAPDomain = ldap.LDAPDomain; //ADHelper.DomainName = ldap.LDAPDomain;
                ADHelper.ADPath = ldap.ADPath;
                ADHelper.ADUser = ldap.ADUser;
                ADHelper.ADPassword = ldap.ADPassword;
                if (ADHelper.IsAccExists(sAMAccountName))
                {
                    del = true;
                    break;
                }
            }
            if (del == true)
            {

                DirectoryEntry de = null;
                DirectoryEntry userEntry = new DirectoryEntry();
                try
                {
                    de = ADHelper.GetDirectoryObject();
                    DirectorySearcher deSearch = new DirectorySearcher(de);
                    deSearch.Filter = "(&(&(objectCategory=person)(objectClass=user))(sAMAccountName=" +
                        sAMAccountName + "))";       // LDAP 查询串
                    SearchResult sr = deSearch.FindOne();
                    userEntry = sr.GetDirectoryEntry();
                    de = userEntry.Parent;
                    de.Children.Remove(userEntry);
                    de.CommitChanges();
                    de.Dispose();
                    userEntry.Dispose();
                    result.ExecResult = ExecResult.Success;
                    return result;
                }
                catch (Exception ex)
                {
                    de.Dispose();
                    userEntry.Dispose();
                    result.ExecResult = ExecResult.Failure;
                    LogHelper.WriteLog(new LogModel(Level.Error, DateTime.Now, "del ADAccount is error: " + ex.Message));
                    return result;
                }
            }
            else
            {
                result.ExecResult = ExecResult.Failure;
                result.ResultMessage = "无此帐号";
                LogHelper.WriteLog(new LogModel(Level.Error, DateTime.Now, "del ADAccount is not  Exists" ));
                return result;
            }

        }

利用ADHelper提供的共有方法，先扫描所有域（格式XML）,如果存在SAMAccountName，则返回True,利用
DirectoryEntry ，和过滤器等类方法进行删除，像是找一个同学，不需要知道年级、班，只需要知道学生编号就好，因为即使手里掌握不同的学校名（域名），因编号是唯一的，也能找到他。
