Adding BSON array to BsonDocument in MongoDB

Adding BSON array to BsonDocument in MongoDB

In MongoDB, you can use the BSON array type to store arrays in a BsonDocument or directly in a MongoDB collection. BSON is a binary representation of JSON-like documents used to store data in MongoDB.

To add a BSON array to a BsonDocument, you can use the BsonArray class from the MongoDB C# driver. Here's an example of how to do it:

using System; using MongoDB.Bson; using MongoDB.Bson.IO; using MongoDB.Bson.Serialization; public class Program { public static void Main() { // Create a BsonDocument and add a BSON array to it BsonDocument document = new BsonDocument(); BsonArray array = new BsonArray { 1, 2, 3, 4, 5 }; document.Add("myArray", array); // Serialize the document to JSON for display string json = document.ToJson(new JsonWriterSettings { Indent = true }); Console.WriteLine(json); } }

Output:

{ "myArray" : [1, 2, 3, 4, 5] }

In this example, we create a BsonDocument called document. We then create a BsonArray called array with five integer values. We add the BsonArray to the BsonDocument using the key "myArray".

The ToJson method is used to serialize the BsonDocument to a JSON string with an indentation for better readability.

If you are directly working with a MongoDB collection, you can insert the BsonDocument with the BSON array into the collection using the MongoDB C# driver's InsertOne or InsertMany methods.
