How to convert JSON to BSON using Json.NET

Question

I have a string that contains a JSON. The only thing I know about this JSON is that it is valid. How to turn this string into BSON?

Answer 1

The BsonWriter of Newtonsoft.Json is obsolete.

You need to add a new nuget-package called Json.NET BSON (just search for newtonsoft.json.bson) and work with BsonDataWriter and BsonDataReader instead of BsonWriterand BsonReader:

public static string ToBson<T>(T value)
{
    using (MemoryStream ms = new MemoryStream())
    using (BsonDataWriter datawriter = new BsonDataWriter(ms))
    {
        JsonSerializer serializer = new JsonSerializer();
        serializer.Serialize(datawriter, value);
        return Convert.ToBase64String(ms.ToArray());
    }

}

public static T FromBson<T>(string base64data)
{
    byte[] data = Convert.FromBase64String(base64data);

    using (MemoryStream ms = new MemoryStream(data))
    using (BsonDataReader reader = new BsonDataReader(ms))
    {
        JsonSerializer serializer = new JsonSerializer();
        return serializer.Deserialize<T>(reader);
    }
}
