title: Multiple conditions for a FilterExpression
body: <p>I am using Condition expression but I'm unable to add more than one condition to a <code>FilterExpression</code>.
  Can any one help? I have posted my source code here.</p>
  
  <p>ConditionExpression with Filters:</p>
  
  <pre><code>  // Filter1
  FilterExpression filter1 = new FilterExpression();
  filter1.FilterOperator = LogicalOperator.And;
  filter1.Conditions.Add(new ConditionExpression("A_LogicalName", ConditionOperator.Equal, id1));
  filter1.Conditions.Add(new ConditionExpression("B_LogicalName", ConditionOperator.Equal, id2));
  query.Criteria.Filters.Add(filter1);
  </code></pre>
  
  <p>// Filter2</p>
  
  <pre><code>FilterExpression filter2 = new FilterExpression();
  filter2.FilterOperator = LogicalOperator.And;
  filter2.Conditions.Add(new ConditionExpression("B_LogicalName", ConditionOperator.Equal, id3));
  filter2.Conditions.Add(new ConditionExpression("C_LogicalName", ConditionOperator.Equal, id4));
  q_ShoppingCartItemQuantityCheck.Criteria.Filters.Add(filter2);  
  </code></pre>
