Playing around with mongo db in .net

05 Apr 2010

Ever since I heard of the NoRM driver for MongoDB I had to try my hands on it. You can find it here: NoRM , mongodb

The first thing is setting up the server. I dropped the binaries into


Next thing I created two batch files. To start the db: start.bat

C:\\MongoDb\\bin\\mongod.exe --dbpath C:\\MongoDb\\data --port 27000 --logpath C:\\MongoDb\\log\\mongodb.log --logappend

The other to access the mongo shell: shell.bat C:\MongoDb\bin\mongo.exe –port 27000

Next thing is creating a simple MVC app that uses MongoDB for storage.

My object of choice is Product:

public partial class Product
  public Product()
    Id = ObjectId.NewObjectId();
  [Column(IsPrimaryKey = true)]
  public virtual ObjectId Id
    get {return _id;}
    set {_id = value;}

 The attribute is for the editor template. Next thing is the controller. Here is the helper for connecting to the database:

  public class ServerHelper
    public static Mongo GetServer()
      return Mongo.Create("mongodb://localhost:27000/MongoMvc");

    public static MongoCollection Collection()
      return GetServer().GetCollection("products");

Note that you don’t need to do a create database or collection.

Insert is straightforward. In order to list all “products” I used an empty Find on the collection. To update I did the following:

    public ActionResult EditPost(ObjectId id)
      var collection = ServerHelper.Collection();
      var product = collection.FindOne(new{ _id = id });
      collection.UpdateOne(new { _id = id }, product);
      return RedirectToAction("Index");

Looks interesting. I’ve not delved into any deeper parts than this yet. I could probably have done this without the additional configuration.
