This document discusses setting up MongoDB on Windows using the .NET framework and C#. It provides an overview of MongoDB and describes how to install and run MongoDB as a service on Windows. It then discusses the MongoDB C# driver, including how to add it to projects using NuGet. It describes the driver's main namespaces and classes for working with BSON documents and connecting to MongoDB databases and collections. The document ends with examples of performing CRUD operations on MongoDB collections from C# code.
Using MongoDB with the .Net Framework
- 1. +Using MongoDB on Windows with the .Net Framework and C#
- 2. Let me introduce myself…Stefano PaluelloAll around geek @ Barcrest Group & Pastesoftstefano.paluello@gmail.comstefanopaluello.wordpress.comTwitter: @palutzhttp://www.pastesoft.com
- 3. What is MongoDB?It’s an open source document oriented database:Full index supportReplication & High AvailabilityScalable (auto-sharding)High performance (written in C++, atomic update,…)Rich query supportMap/ReduceGridFS (store files without problem)Commercial support
- 4. Setting up MongoDB on WindowsDownload your version (better the 64bit Production release) from the official website:http://www.mongodb.org/downloads
- 5. Running MongoDB server…Best place where to look at (Windows quickstart):http://www.mongodb.org/display/DOCS/Quickstart+WindowsUnzip, create log and data dir, run it
- 6. Ok. Are we running?Let’s connect to the shell and check it$mongodir\bin\mongo.exe
- 7. MongoDB can run as serviceOfficial guide:http://www.mongodb.org/display/DOCS/Windows+ServiceEasy way: $mongodir\bin\mongod –installLet’s add some “flavour”:$mongodir\bin\mongod --logpath .\log\logs --logappend --dbpath .\data –directoryperdb –installTo manage it, NET START mongos, NET STOP mongos
- 8. MongoDB C#/.Net driverOfficial, high performance, fully featured C# driver supported by 10genNow at version 1.2Built and tested against MongoDB 1.8.3 e 2.0.0 on :Visual Studio 2008, Visual Studio 2010MonoDevelop 2.6 (Mono 2.10)It can be downloaded from github.com: http://github.com/mongodb/mongo-csharp-driverNuGet:PM> Install-Package mongocsharpdriverhttp://www.nuget.org/List/Packages/mongocsharpdriver
- 9. MongoDB C#/.Net driver on NuGet
- 10. MongoDB C#/.Net driverTwo main (separated) assemblies:MongoDB.Bson.dllMongoDB.Driver.dll (you can use other drivers)Namespaces (required)MongoDB.Bson;MongoDB.Driver;Namespace (additional) MongoDB.Bson.IO, MongoDB.Bson.Serialization; MongoDB.Bson.Serialization.*, MongoDB.Driver.GridFs
- 11. BSON NamespaceRepresent the BSON Object ModelA set of classes that handle all the specification of BSON documents (I/O, serialization, in-memory object model)Main classes:BsonDocumentBsonElementBsonValue (abstract class), with BsonTypeenum propertyBsonArrayBsonDateTimeBsonDocumentBsonInt32BsonObjectIdBsonString
- 12. BSON Object ModelBsonDocument is the main classBsonDocument is a collection of elements (BsonElements )BsonElement is a name/value pair where the value is a BsonValue (with its own BsonType)The BsonElement class is seldom used directly cause it’s created as needed implicitly:document.Add(new BsonElement(“Name”, “Stefano”));document.Add(“Name”, “Stefano”));
- 13. MongoDB.DriverMain classes (all thread-safe):MongoServerMongoDatabaseMongoCollection<TDocument>MongoCursor<Tdocument> (only when frozen)MongoServersrv = MongoServer.Create();Every URL has a MongoServer instance (different Create calls with the same URL return with the same MongoServer instanceNOT put in the session state (NOT serializable)
- 14. MongoDB.DriverMongoServersrv = MongoServer.Create();Every URL has a MongoServer instance different Create() calls with the same URL return with the same MongoServerinstanceDo NOT put in the session state (NOT serializable)The driver manage a Connection Pools (one Connection Pools for every server)The connections are shared with all threads
- 15. MongoDB DriverMongoCollection :The class manages a collection of BsonDocument in a MongoDB databaseMongoCollection<TDefaultDocument>:Manage a collection of document, with the default type specified by the TDefaultDocument parameterGetCollection
- 16. MongoCollection classCRUD with Mongo – Query a collectionFindOne and FindOneAs<T>IMongoQuery objects (QueryComplete)Find(query)
- 17. MongoCollection classCRUD with MongoDB - InsertThere are many ways to insert data into a MongoDB collection (using the BsonDocument or any object that can be serialized
- 18. MongoCollection classCRUD with MongoDB – Update and SaveThere are many ways to update a document
- 19. MongoCollection classCRUD with MongoDB – DeleteThere are many ways to delete a Document
- 20. Let’s play a bit with the code…
- 23. Chrome Webstore – Mongo Live
- 24. Another code demoGet dynamics with C#
