How to use a string instead of a stream?

Question

I need to use this:

http://www.newtonsoft.com/json/help/html/SerializeToBson.htm

This is code to convert object to BSON format. The code which interests me is this:

System.IO.MemoryStream stream = new System.IO.MemoryStream(); using (Newtonsoft.Json.Bson.BsonWriter writer = new Newtonsoft.Json.Bson.BsonWriter(stream)) { Newtonsoft.Json.JsonSerializer serializer = new Newtonsoft.Json.JsonSerializer(); serializer.Serialize(writer, message); }

However, I want the result in a string. So do I really have to use a stream or a file to write stuff in, then read it to put it in the string?

There must be a better way to do this?

You can get the string from the stream using StreamReader.ReadToEnd():

 string bsonText = ""; using(MemoryStream stream = new MemoryStream()) using(StreamReader reader = new StreamReader(stream)) using (BsonWriter writer = new Newtonsoft.Json.Bson.BsonWriter(stream)) { JsonSerializer serializer = new JsonSerializer(); serializer.Serialize(writer, message); stream.Position = 0; bsonText = reader.ReadToEnd(); }

Or also, Encoding.UTF8.GetString():

 using(MemoryStream stream = new MemoryStream()) using (BsonWriter writer = new Newtonsoft.Json.Bson.BsonWriter(stream)) { JsonSerializer serializer = new JsonSerializer(); serializer.Serialize(writer, message); bsonText = Encoding.UTF8.GetString(stream.ToArray()); }

BTW who knows what you're going to get from this, since BSON is a binary object representation, it's not like JSON!
