Examples

// Fetch the average of estimatedvalue for all opportunities.  This is the equivalent of 
                    // SELECT AVG(estimatedvalue) AS estimatedvalue_avg ... in SQL.
                    System.Console.WriteLine("===============================");
                    string estimatedvalue_avg = @" 
                    <fetch distinct='false' mapping='logical' aggregate='true'> 
                        <entity name='opportunity'> 
                           <attribute name='estimatedvalue' alias='estimatedvalue_avg' aggregate='avg' /> 
                        </entity> 
                    </fetch>";

                    EntityCollection estimatedvalue_avg_result = _serviceProxy.RetrieveMultiple(new FetchExpression(estimatedvalue_avg));

                    foreach (var c in estimatedvalue_avg_result.Entities)
                    {
                        decimal aggregate1 = ((Money)((AliasedValue)c["estimatedvalue_avg"]).Value).Value;
                        System.Console.WriteLine("Average estimated value: " + aggregate1);
