Convert BSON to valid JSON in C#

Convert BSON to valid JSON in C#

To convert BSON to valid JSON in C#, you can use the Newtonsoft.Json package to deserialize the BSON data into a JSON string. Here's an example:

using System; using System.IO; using MongoDB.Bson; using MongoDB.Bson.IO; using Newtonsoft.Json; namespace MyApp { public class MyProgram { public static void Main() { // read BSON data from a file var bsonData = File.ReadAllBytes("example.bson"); // deserialize the BSON data to a BsonDocument var bsonReader = new BsonBinaryReader(new MemoryStream(bsonData)); var bsonDocument = BsonSerializer.Deserialize<BsonDocument>(bsonReader); // convert the BsonDocument to a JSON string var jsonString = bsonDocument.ToJson(new JsonWriterSettings { OutputMode = JsonOutputMode.Strict }); // print the JSON string Console.WriteLine(jsonString); } } }

In this example, we first read the BSON data from a file into a byte array.

We then deserialize the BSON data to a BsonDocument using the BsonSerializer.Deserialize method and a BsonBinaryReader that reads from a MemoryStream.

Finally, we convert the BsonDocument to a JSON string using the ToJson method on the BsonDocument. We use a JsonWriterSettings object to specify the output mode as JsonOutputMode.Strict, which produces a valid JSON string. We then print the JSON string to the console.

Note that if the BSON data is an array of objects, you can use BsonSerializer.Deserialize<BsonArray> to deserialize it into a BsonArray object, which can then be converted to a JSON string using ToJson.
