C# Determine whether time periods intersect

1. Determine whether two start and end times intersect:

public static bool IsTimeBetween(TimeSpan input, TimeSpan start, TimeSpan end, bool fromInclusice, bool toInclusive)
        {
            //http://www.php.cn/
            // 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. Pass in the expression of the start and end times, determine the intersection with the known time period, and generate a Mongo query:

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;
        }

From and To are two time attributes
