ParameterFields pFields = new ParameterFields();
ParameterField pField1 = new ParameterField();
ParameterField pField2 = new ParameterField();
ParameterDiscreteValue pDisValue1 = new ParameterDiscreteValue();
ParameterDiscreteValue pDisValue2 = new ParameterDiscreteValue();
pField1.Name = "id";
pField2.Name = "section";
pDisValue1.Value = id;
pField1.CurrentValues.Add(pDisValue1);
pFields.Add(pField1);
pDisValue2.Value = section;
pField2.CurrentValues.Add(pDisValue2);
pFields.Add(pField2);
