C# MongoDB

Introduction to MongoDB and C#

MongoDB is a popular NoSQL database known for its high performance, scalability, and flexibility. In C#, the most common way to interact with MongoDB is through the MongoDB.Driver library, which provides a powerful API to perform CRUD operations, indexing, and more on MongoDB collections. This guide will walk you through the basics of using MongoDB with C#.

Setting Up MongoDB.Driver in C#

To use MongoDB with C#, you must first install the MongoDB.Driver package. You can do this using NuGet Package Manager in Visual Studio or via the command line.

Connecting to a MongoDB Database

Once the driver is installed, you can establish a connection to your MongoDB instance. The following example shows how to connect to a local MongoDB server.

Inserting Documents into a Collection

After establishing a connection, you can perform operations like inserting documents into a collection. Here's how to insert a new document into a collection named users.

Querying Documents from a Collection

To retrieve documents from a collection, you can use various query methods provided by the driver. The following example demonstrates how to find documents where the age is greater than 25.

Updating Documents in a Collection

You can also update existing documents in a collection. The following example updates the email of a user whose name is "Alice".

Deleting Documents from a Collection

Deleting documents is straightforward with the MongoDB.Driver. Here's an example that deletes documents where the age is less than 25.

Conclusion and Next Steps

In this guide, you've learned the basics of using MongoDB with C# through the MongoDB.Driver. You can now create, read, update, and delete documents in a MongoDB collection. As a next step, consider exploring more advanced features like indexing, aggregation, and using LINQ with MongoDB.Driver.
