Sample code for adding/deleting MOSS alerts

Please somebody tell me there's a better way to delete an alert. I'm too lazy to spend more time on this...

Create an alert...

   1: try

   2: {

   3:     string[] alertUsers = web.Alerts.GetUniqueUsers();

   4:     Guid alertGuid = web.Alerts.Add(

   5:         web.Lists[_documentLibraryName], 

   6:         SPEventType.Add, 

   7:         SPAlertFrequency.Immediate);

   8:     SPAlert alert = web.Alerts[alertGuid];

   9:     alert.User = web.SiteUsers[roleName];

  10:     alert.Update();

  11: }

  12: catch (Exception e)

  13: {

  14:     throw new Exception("Error creating document library notification for company.", e);

  15: }

Delete an alert...

   1: string[] usersWithAlerts = web.Alerts.GetUniqueUsers();

   2: //check to see if there is an alert configured for this role

   3: if (Array.IndexOf(userName) >= 0)

   4: {

   5:     SPList docList = web.Lists[_documentLibraryName];

   6:     for( int i = web.Alerts.Count -1; i >= 0; i--)

   7:     {

   8:         SPAlert alert = web.Alerts[i];

   9:         if (alert.List = docList)

  10:         {

  11:             if (alert.User.Name == roleUserName)

  12:             {

  13:                 web.Alerts.Delete(alert.ID);

  14:             }

  15:         }

  16:     }

  17: }
