How to Join a AndCondition and a OrCondition in one?

  Hi there,
  
  I'm building a Notification Services(NS) Application, and i have a web based interface to add subscriptions to my NS instance. But i'm having a problem with the definition of the UserCondition.
  
  Here is the problem:
  
  I want to add some complex conditions both with "and" or "or" but it only seems to let me have one type of condition.
  
  Here is some code i made:
  
             public Subscription AddConditions(int index, Subscription s, string subscriber,
              ArrayList tipos, ArrayList campos, ArrayList condicoes, ArrayList valores)
          {
              s = new Subscription(subscriber);
  
              AndCondition and = new AndCondition();
              OrCondition or = new OrCondition();
  
              ConditionTree c;
  
              string op;                    
  
              for (int i = 0; i < campos.Count; i++)
              {
                  op = condicoes[i].ToString();
                  Condition cond;
  
                  if (tipos[i].ToString() == "AND")
                  {                   
                    
                      switch (op)
                      {
                          case "=": cond = new AndCondition(new SimpleLeafCondition(
                              new FieldValue(campos[i].ToString()), SimpleOperator.Equals, valores[i].ToString()
                              ));
                              and.Children.Add(cond);
                              break;
                          case "<>": cond = new AndCondition(new SimpleLeafCondition(
                              new FieldValue(campos[i].ToString()), SimpleOperator.NotEquals, valores[i].ToString()
                              ));
                              and.Children.Add(cond);
                              break;
  
                          case "<": cond = new AndCondition(new SimpleLeafCondition(
                             new FieldValue(campos[i].ToString()), SimpleOperator.LessThan, valores[i].ToString()
                             ));
                              and.Children.Add(cond);
                              break;
  
                          case "<=": cond = new AndCondition(new nsr.SimpleLeafCondition(
                          new FieldValue(campos[i].ToString()), SimpleOperator.LessThanOrEqualTo, valores[i].ToString()
                          ));
                              and.Children.Add(cond);
                              break;
  
                          case ">": cond = new AndCondition(new SimpleLeafCondition(
                          new FieldValue(campos[i].ToString()), SimpleOperator.GreaterThan, valores[i].ToString()
                          ));
                              and.Children.Add(cond);
                              break;
  
                          case ">=": cond = new AndCondition(new SimpleLeafCondition(
                          new FieldValue(campos[i].ToString()), SimpleOperator.GreaterThanOrEqualTo, valores[i].ToString()
                          ));
                              and.Children.Add(cond);
                              break;
                          default:
                              break;
                      }
                  }
                  else
                  {   
  
                      switch (op)
                      {
                          case "=": cond = new OrCondition(new SimpleLeafCondition(
                              new FieldValue(campos[i].ToString()), SimpleOperator.Equals, valores[i].ToString()
                              ));
                              or.Children.Add(cond);
                              break;
                          case "<>": cond = new OrCondition(new SimpleLeafCondition(
                              new FieldValue(campos[i].ToString()), SimpleOperator.NotEquals, valores[i].ToString()
                              ));
                              or.Children.Add(cond);
                              break;
  
                          case "<": cond = new OrCondition(new SimpleLeafCondition(
                             new FieldValue(campos[i].ToString()), SimpleOperator.LessThan, valores[i].ToString()
                             ));
                              or.Children.Add(cond);
                              break;
  
                          case "<=": cond = new OrCondition(new nsr.SimpleLeafCondition(
                          new nsr.FieldValue(campos[i].ToString()), SimpleOperator.LessThanOrEqualTo, valores[i].ToString()
                          ));
                              or.Children.Add(cond);
                              break;
  
                          case ">": cond = new OrCondition(new SimpleLeafCondition(
                          new FieldValue(campos[i].ToString()), SimpleOperator.GreaterThan, valores[i].ToString()
                          ));
                              or.Children.Add(cond);
                              break;
  
                          case ">=": cond = new OrCondition(new SimpleLeafCondition(
                          new FieldValue(campos[i].ToString()), SimpleOperator.GreaterThanOrEqualTo, valores[i].ToString()
                          ));
                              or.Children.Add(cond);
                              break;
                          default:
                              break;
                      }
                  }
              }
  
              if(and.Children.Count>0)
                  c.Children.Add(and);
              if (or.Children.Count > 0)
                  c.Children.Add(or);
  
              s.UserCondition = c;
  
              return s;
  
          }
  
  The problem is that the ConditionTree needs to be initialized or i get a runtime error when i try to add ( c.Children.Add(and);), but it only lets me initialize it with AndCondition or OrCondition, like ConditionTree c = new AndCondition(); or ConditionTree c= new OrCondition(); !
  
  Does anyone know a way to add this two types of Conditions in one?
  
  Thanks in advance for any help :)
