Use a MongoDB database in a Windows app

  • Article

This article contains the steps required to enable working with a MongoDB database from a Windows app. It also contains a small code snippet showing how you can interact with the database in code.

Set up your solution

This example can be used with any WPF, Windows Forms, WinUI 3, and UWP project to connect your Windows app to MongoDB. Follow these steps to install the package and try out the example code to read data from an existing MongoDB database.

Open the Package Manager Console (View -> Other Windows -> Package Manager Console). Use the command Install-Package MongoDB.Driver to install the NuGet package for the official driver for MongoDB. This will allow you to programmatically access MongoDB databases.

Test your connection using sample code

The following sample code gets a collection from a remote MongoDB client, then adds a new document to that collection. Then it uses MongoDB APIs to retrieve the new size of the collection as well as the inserted document, and prints them out.

var client = new MongoClient("mongodb://10.xxx.xx.xxx:27017");
IMongoDatabase database = client.GetDatabase("foo");
IMongoCollection<BsonDocument> collection = database.GetCollection<BsonDocument>("bar");
var document = new BsonDocument
{
     { "name","MongoDB"},
     { "type","Database"},
     { "count",1},
     { "info",new BsonDocument { { "x", 203 }, { "y", 102 } }}
};
collection.InsertOne(document);
long count = collection.CountDocuments(document);
Console.WriteLine(count);
IFindFluent<BsonDocument, BsonDocument> document1 = collection.Find(document);
Console.WriteLine(document1.ToString());

Note that the IP address and database name will need to be customized. The port, 27017, is the default MongoDB port number. In a production application, connection information such as server address and database name should be stored in app configuration rather than hard-coded (see Adding Azure App Configuration by using Visual Studio Connected Services).
