I have read through the mongodb documentation and cannot seem to find out how to create a new database. For example, in the documentation it says I can access the "test" database like this: db.test.find() Now what if I want to create my own database using syntax like this: db.MyDB.find() Also, is there any documentation I can read online I can further read about creating databases and collections using the DOS interface and the c# driver? I may be wrong, but buried in this documentation it looks like the call to GetDatabase on the server object will actually create the database if it has not

I've got a model that looks like: public class Record { public Record() { Created = DateTime.Now; } public string Id { get; set; } public string ApplicationId { get; set; } public Dictionary<string, dynamic> Values { get; set; } public DateTime Created { get; set; } } that's stored in MongoDB using the MongoDB C# Driver. This works GREAT when I do things like: { applicationId: "52f52db8008a280f583c9ff6", values: { "52f9410a324e68055f39f8c0": 245234 "52f941096d82a531e700e56b": "sdfasdf" "52fa4a96e0b2e0d4e61d0a03": "52fa4a9b91c477e367ab99e6" } } but when I try to add an array of strings like: {

I have objects with 3 string fields Country, Province, City. They can contain null or some string name. I wanna query all data with the exact same values. For Example i need all data where City = null, Province = "WA", Country = "USA" I created BsonDocument: var lookup = new QueryDocument { {"GeoPosition.City", userLocation.City}, {"GeoPosition.Province", userLocation.Province}, {"GeoPosition.Country", userLocation.Country} }; But null field was thrown away and document looks like: { "GeoPosition.Province" : "WA", "GeoPosition.Country" : "USA" } If i'm triing to use Query.EQ("GeoPosition.City"

I want to know if it's possible to use TTL on nested documents. Scenario I have Account and inside I have Sessions . Sessions need to expire in 30 minutes. I've set everything up but obviously when I set TTL index on Account.Sessions.EndDateTime it removes the whole Account . Can I make sure it removes only Session ? This is what it looks like in database. Notice how it will delete whole Account and not only Session when EndDateTime will come. { "_id" : ObjectId("53af273888dba003f429540b"), "Email" : "steve@s3te5ve.com", "PasswordHash" : "CZaBEQRbwWNgJBjyhks7gH0Z3v5ZvDkW29pryF0DEXyE8rIw0NA4x39
