我在c#中有以下查询:
var filter = Builders<ME_UserInbox>.Filter.And(
Builders<ME_UserInbox>.Filter.Eq(n => n.UserId, userId),
Builders<ME_UserInbox>.Filter.ElemMatch(inbx => inbx.Inbox, msg => msg._id == msgId));
var update = Builders<ME_UserInbox>.Update.PullFilter(inbx => inbx.Inbox, msgs => msgs._id == msgId);
var upsert = new UpdateOptions()
{
IsUpsert = false
};
await collection.FindOneAndUpdateAsync(filter, update, upsert);
现在,如果我在最后一行之后写.Result
。在更新之前或之后获取文档?
TIA。
