使用Python读取TestTrack记录- Part3 动态生成Linq to xml查询语句筛选条件

private int QueryDefectNum(string type, string creater, string status, DateTime start, DateTime end)
{
var query = from defect in element.Descendants("Defect")
where
(!string.IsNullOrEmpty(type) ? defect.Element("type").Value.contains(type) : true) &&
(!string.IsNullOrEmpty(creater) ? defect.Element("creater").contains(creater) : true) &&
(!string.IsNullOrEmpty(status) ? defect.Element("status").contains(status) : true) &&
Convert.ToDateTime(defect.Element("date-created").Value) >= start &&
Convert.ToDateTime(defect.Element("date-created").Value) <= end
select defect;

return query.count;
}
