I have a collection like this: [{ "_id": 1, "OtherProperties": 100 "PersonInventory": [{ "FirstName": "Joe", "MiddleName": "Bob", "LastName": "Blogs", "PersonId": 1 }] },{ "_id": 2, "OtherProperties": 1005 "PersonInventory": [{ "FirstName": "Joe", "MiddleName": "Bob", "LastName": "Blogs", "PersonId": 1 }] }] And I am trying to select all the unique persons in the root docs using here newer type inference mongodb c# driver syntax. Tried this so far but getting errors saying the method is not available (i think this is to do with the grouping), can anyone show me where I am going wrong?

I have a group of statuses of pretend payments, each with a payment ID. I want to get the latest status for each payment ID. The test I have creates some dummy data and then tried to query it. I've got this far: [Test] public void GetPaymentLatestStatuses() { var client = new TestMongoClient(); var database = client.GetDatabase("payments"); var paymentRequestsCollection = database.GetCollection<BsonDocument>("paymentRequests"); var statusesCollection = database.GetCollection<BsonDocument>("statuses"); var payment = new BsonDocument { { "amount", RANDOM.Next(10) } }; paymentRequestsCollection

I've picked up a piece of code that is using the MongoDB driver like this to get a single object from a collection...this can't be right, can it? Is there a better way of getting this? IMongoCollection<ApplicationUser> userCollection; .... userCollection.FindAsync(x => x.Id == inputId).Result.ToListAsync().Result.Single(); Yes, there is. First of all don't use FindAsync , use Find instead. On the IFindFluent result use the SingleAsync extension method and await the returned task inside an async method: async Task MainAsync() { IMongoCollection<ApplicationUser> userCollection = ...; var

I'm using the Mongo LINQ Driver for C#, works great. Sorting a lot of properties but heres a problem I can't solve, its probably simple. var identifierList = new []{"10", "20", "30"}; var newList = list.Where(x => identifierList.Contains(x.Identifier)); This is NOT supported ... So I could do something like: var newList = list.Where(x => x.Identifier == "10" || x.Identifier == "20" || x.Identifier == "30"); But since the list is variable ... how do I construct the above? Or are there even better alternatives? The list is of type IQueryable<MyCustomClass> For information ... this is used as a

The Mongodump documentation specifies you can dump using a specific query i.e. mongodump --host localhost --db mydb --collection testCollection --query "{SomeKey: 'some value'}" I'm storing _ids fields as BinData, is it possible to query on this? I've tried mongodump --host localhost --db mydb --collection testCollection --query "{_id: 'BinData(3,ryBRQ+Px0kGRsZofJhHgqg==)'}" With no luck. This needs a lot of escaping, unfortunately. Also, you'll have to use the $binary representation instead, e.g. mongodump --host localhost --db test --collection bd --query "{\"_id\" : { \"$binary\" : \"ryBRQ
