.NET MongoDB

Introduction to .NET MongoDB

MongoDB is a popular NoSQL database that stores data in flexible, JSON-like documents. In .NET, developers can use the MongoDB.Driver package to interact with MongoDB databases. This guide will explore how to integrate MongoDB with .NET applications, covering installation, basic operations, and best practices.

Installing MongoDB.Driver

To start using MongoDB with .NET, you'll need to install the MongoDB.Driver NuGet package. This package provides the necessary classes and methods to interact with MongoDB databases.

You can install it via the NuGet Package Manager Console with the following command:

Connecting to MongoDB

Once the driver is installed, establish a connection to your MongoDB server. You'll typically need a connection string, which includes the server address and authentication details if required.

Here's a basic example of how to connect to a MongoDB database using C#:

Performing CRUD Operations

CRUD operations (Create, Read, Update, Delete) are fundamental when working with databases. The MongoDB.Driver provides straightforward methods to perform these operations.

Here's how you can perform these operations on a collection named users:

Using Strongly Typed Models

For better type safety and maintainability, you can use strongly typed models instead of BsonDocument. Define a class representing your document structure.

Best Practices for .NET and MongoDB

• Use connection pooling to manage connections efficiently.
• Leverage asynchronous methods provided by MongoDB.Driver for non-blocking operations.
• Validate and sanitize input data to prevent injection attacks.
• Organize your code to separate data access logic from business logic.
