Using the Driver<\/h1>\n
To use the driver, simply create a new project and add a reference to it. For our sample, create a new console application. Then right click on references, choose add reference, and find the MongoDB.Driver.dll<\/span> and add it.<\/p>\n After adding the reference we are ready to write code. Here is a very simple snippet of code to test out Mongo. This is the full content of Program.cs<\/span>.<\/p>\n The comments should explain most of what is happening. One thing worthy of note is the Document<\/span> class. The Document<\/span> class is much like a dictionary. Remember that MongoDB does not have a static schema. Therefore a dictionary serves the purpose well since it is dynamic by nature.<\/p>\n There are other drivers (such as NoRM<\/a>) out there that will map a static C# class into MongoDB much like NHibernate or another ORM, however, then you lose some of the benefit of the dynamic schema, however, depending on your needs, this may be acceptable.<\/p>\n Note that to use this, you need to have the instance of MongoDB up and running. You can follow the instructions from last week\u00e2\u20ac\u2122s post<\/a> to get it installed. If its already installed, just open a command prompt, go to the bin folder in the install directory (in my case C:\\mongodb\\bin<\/span>), and execute the command mogod.<\/span><\/p>\n![\"image\"](\"https:\/\/www.chrisedwards.dreamhosters.com\/blog\/wp-content\/uploads\/2010\/05\/image_thumb.png\" "\\"image\\"")
