我目前有一个可用的多级谓词......
var predicate = PredicateBuilder.New<Patient>();
foreach (var code in codeArray) // ect..["AB12", "W231", "Q213"]
{
string localCode = code;
predicate.Or(p => p.Requests.Any(
u => u.Records.Any(
t => t.OutgoingRecords.Any(
s => s.Code == localCode)
)
)
);
}
res = query.AsExpandable().Where(predicate);
// Query is built up from an outside source and is eventually turned into a list via .ToListAsync()
除非我知道它以......的形式生成查询,否则这很好。
query = p => p.PatientEpisodes.Any(u => u.EpisodeGroupings.Any(t => t.EpisodeDiagnoses.Any(s => s.Code == 'AB12'))) ||
p.PatientEpisodes.Any(u => u.EpisodeGroupings.Any(t => t.EpisodeDiagnoses.Any(s => s.Code == 'W231'))) ||
p.PatientEpisodes.Any(u => u.EpisodeGroupings.Any(t => t.EpisodeDiagnoses.Any(s => s.Code == 'Q213')))
当我真正应该制作的是......时,这有点过分(而且有点不对)
query = p => p.PatientEpisodes.Any(u => u.EpisodeGroupings.Any(t => t.EpisodeDiagnoses.Any(s => s.Code == 'AB12' || s.Code == 'W312' || s.Code == 'Q213')))
有没有办法在查询的子级别插入谓词,如下所示?到目前为止,我目前的尝试失败了。
var predicate = PredicateBuilder.New<RecordCode>();
foreach (var code in codeArray)
{
string localCode = code;
predicate.Or(p => p.Code == localCode);
}
query = query.AsExpandable().Where(
s => s.Requests.Any(
c => c.Records.Any(
d => d.OutgoingRecords.Any(predicate))));
非常感谢提前。
