我有以下查询在预期的mongo shell上工作。
db.getCollection('personnels').update(
{
_id: ObjectId("55f6728b9d73a15807885de8"),
"Devices._id":ObjectId("55fa5f7ac9e7863a3836e331")
},
{
$pull:{ "Devices.$.DeviceCloudFolders": { "CloudFolderId": ObjectId("5615124b06275f072040c4f1")}}
}
);
这是我的文档结构:
{
"_id" : ObjectId("55f6728b9d73a15807885de8"),
"FirstName" : "Tolga",
"Devices" : [
{
"_id" : ObjectId("55fa5f7ac9e7863a3836e331"),
"Name" : "tolga-laptop",
"DeviceCloudFolders" : [{
"AuthorityType" : 1,
"CloudFolderId" : ObjectId("55f96db5c9e7863a3836e310"),
"Status" : 1
}],
"Status" : 1
}
],
"Status" : 1
}
我需要在C#中使用它并且无法弄清楚如何使用它。
我从这些界线开始:
var filter = Builders<Personnel>.Filter.And(
Builders<Personnel>.Filter.Eq("_id", ownerPersonnelId),
Builders<Personnel>.Filter.Eq("Devices._id", _id));
var update = Builders<Personnel>.Update.PullFilter("Devices.$.DeviceCloudFolders", /*couldn't figure out what goes here*/))
Personnels.FindOneAndUpdateAsync(filter, update);
答案 0 :(得分:7)
我不确定,但您可以尝试使用它:
var update = Builders<Personnel>.Update.PullFilter(
"Devices.$.DeviceCloudFolders",
Builders<DeviceCloudFolder>.Filter.Eq("CloudFolderId", _cloudFolderId));
