What is the easiest way to convert JSON into BSON in .net world

Question

I just started working on MongoDB. From my JavaScript client I am sending a JSON string to ASP.NET WEB API project. Is it possible to use this JSON string directly and save it into MongoDB? I also want to know whether this approach make sense ?

I am thinking of passing the JSON from client and on the server side read the string as

 [System.Web.Mvc.HttpPost]
    public dynamic SaveData([FromBody] string data)
    {

        System.Web.HttpContext.Current.Request.Form[0]
        return null;
    }

Answer 1

Try this:

string json = "...";
BsonDocument.Parse(json);
