C# 判断时间段是否相交的实现方法
1. 判断两个起止时间是否相交:
public static bool IsTimeBetween(TimeSpan input, TimeSpan start, TimeSpan end, bool fromInclusice, bool toInclusive) { //http://stackoverflow.com/questions/592248/how-can-i-check-if-the-current-time-is-between-in-a-time-frame // see if start comes before end if (end < start) { return ((toInclusive && (input <= end)) || (!toInclusive && (input < end))) || ((fromInclusice && (input >= start)) || (!fromInclusice && (input > start))); } else { return ((fromInclusice && (input >= start)) || (!fromInclusice && (input > start))) && ((toInclusive && (input <= end)) || (!toInclusive && (input < end))); } }
2. 传入起止时间的表达式,判断与已知时间段的交集,生成Mongo查询:
public IMongoQuery GetMongoQueryIntersectWith<TCollection>( Expression<Func<TCollection, DateTime>> fromExp, Expression<Func<TCollection, DateTime>> toExp) { var rangeTo = Query.And(Query<TCollection>.GTE(toExp, To), Query<TCollection>.LTE(fromExp, To)); var rangeFrom = Query.And(Query<TCollection>.GTE(toExp, From), Query<TCollection>.LTE(fromExp, From)); var rangeQuery = Query.Or(rangeTo, rangeFrom, Query.And(Query<TCollection>.GTE(fromExp, From),Query<TCollection>.LTE(toExp, To))); return rangeQuery; }
其中From和To为两个时间属性
