MongoDbGenericRepository

An example of generic repository implementation using the MongoDB C# Sharp 2.0 driver (async)

Now available as a nuget package: https://www.nuget.org/packages/MongoDbGenericRepository/

Usage examples

This repository is meant to be inherited from.

You are responsible for managing its lifetime, it is advised to setup this repository as a singleton.

Here is an example of repository usage, where the TestRepository is implementing 2 custom methods:

    public interface ITestRepository : IBaseMongoRepository
    {
        void DropTestCollection<TDocument>();
        void DropTestCollection<TDocument>(string partitionKey);
    }
    
    public class TestRepository : BaseMongoRepository, ITestRepository
    {
        public TestRepository(string connectionString, string databaseName) : base(connectionString, databaseName)
        {
        }

        public void DropTestCollection<TDocument>()
        {
            _mongoDbContext.DropCollection<TDocument>();
        }

        public void DropTestCollection<TDocument>(string partitionKey)
        {
            _mongoDbContext.DropCollection<TDocument>(partitionKey);
        }
    }

The repository can be instantiated like so:

ITestRepository testRepository = new TestRepository(connectionString, "MongoDbTests");

To add a document, its class must inherit from the Document class or implement the IDocument interface:

    public class MyDocument : Document
    {
        public ReadTestsDocument()
        {
            Version = 2; // you can bump the version of the document schema if you change it over time
        }
        public string SomeContent { get; set; }
    }

The IDocument interface can be seen below:

    /// <summary>
    /// This class represents a basic document that can be stored in MongoDb.
    /// Your document must implement this class in order for the MongoDbRepository to handle them.
    /// </summary>
    public interface IDocument
    {
        DateTime AddedAtUtc { get; set; }
        Guid Id { get; set; }
        int Version { get; set; }
    }
