It is not recommended that you allow duplicate names, and this option exists only to allow handling existing BSON documents that might have duplicate names. The C driver supports authentication in a couple of ways. WriteLine “Press enter to exit” ; Console. So let’s go ahead and fetch a database called school for which we’ll work with:. Driver; using System; using System. EQ is using the Query builder class to help you build the query. Instead they return a cursor that can be enumerated to retrieve the results of the query.

Get a hold of an object of type IMongocollection which represents the collection we want to work with: To see this in action, we move on to updating our code base and running the application:.
The GetDatabase method returns an object which is a representation of a database, from which we can access different collections and manipulate the database. Like BsonDocumentthe type of the elements is Mingodb. Net driver is clear and we know how to insert mongoeb s. A class is not thread safe unless specifically documented as being thread safe.
Getting Started with the CSharp Driver — MongoDB Manual
The value of address is a nested BSON document. The IDictionary overloads initialize a BsonDocument from a dictionary. There are three ways to create and populate a BsonDocument: BsonArray has the following constructors:.
An example of doing this would be: For example, you could correct an error in the title of a book mohgodb The full documentation for connection strings can be found at Connection String and read preferences at http: The standard connection string format is:. Instead they return a cursor that mongoxb be enumerated to retrieve the results of the query.
Working with MongoDB in .NET (Part 1): Driver Basics & Inserting Documents
We are currently building the C Driver with Visual Studio The czharp program is very simple and just copies the DLLs to your specified installation directory.
If you want to store the client object in a global variable you can. Instances of MongoCursor are not thread safe, at least not until they are frozen see below.
The fluent interface works well when you are setting only a few values. There are various levels of WriteConcernand this class is used to represent those levels. The one we’re interested in is the GetDatabase method which will automatically create a database for us.
GitHub flavored markdown supported. I’ll add an async method within the Main method because we’ll be working with the async methods from the driver. There is a concrete subclass of BsonValue for each of the csbarp defined by the BsonType enum.
These eliminate the need for almost all calls to BsonValue constructors or Create methods. Also, there is a synchronous version of this method:.
He also gets involved in design research and customer support for Unlike the As[Type] methods, the To[Type] monbodb perform some limited conversion between convertible types, like int and double.
A string can be converted to a numeric type, but an exception will be thrown if the string cannot be parsed as a value of the target type.

Note that the return value of the indexers is BsonValuenot BsonElement. There are several ways to obtain an instance of BsonValue: After you clone the repository, we recommend you set the local setting for core.
It is not recommended that you allow duplicate names, and this option exists only to allow handling existing BSON documents that might have duplicate names.
