MongoDB使用记录

查询

public List<CheckDataEntity> GetList()
{
     Int64 startTime = Stopwatch.GetTimestamp();//获取计时器机制中当前时间的最小单位数　可以理解为时钟周期
     var filterBuilder = Builders<CheckDataEntity>.Filter;
     var start = new DateTime(2023, 02, 06, 0, 0, 0);
     var end = (new DateTime(2023, 02, 22, 0, 0, 0));
     List<CheckDataEntity> list = checkDataService.Find(x =>x.deviceAddress == "4"& (x.createTime >= start &
     x.createTime <= end)).ToList();
     double endTime = (Stopwatch.GetTimestamp() - startTime) / (double)Stopwatch.Frequency;//获取以每秒计时周期数表示的计时器频率。此字段为只读
     return list;
}
