Dynamic QueryExpression多多选项集条件查询

 string[] sales_type_list = sales_type.Split(',');
 int[] hikingValue = new int[20];
 for (int i = 0; i < sales_type_list.Length; i++)
 {
      hikingValue[i] = int.Parse(sales_type_list[i]);
 }
 ConditionExpression condition = new ConditionExpression("new_selling_format", ConditionOperator.ContainValues, hikingValue);
 FilterExpression filter = new FilterExpression();
 filter.AddCondition(condition);
//查询
 QueryExpression q2 = new QueryExpression();
 q2.EntityName = "new_file_config_detail";
 q2.ColumnSet = new ColumnSet(true);
 q2.Criteria.AddCondition("new_file_configid", ConditionOperator.Equal, e2.Entities[0].Id);
 q2.Criteria.AddCondition("new_account_type", ConditionOperator.Equal, user_type);
 q2.Criteria.AddFilter(filter);
 EntityCollection e = service.RetrieveMultiple(q2);//获取实体信息
