Writing JSON to a stream without buffering the string in memory

Question

I would like to write JSON to a Stream by building the document up explicitly. For example:

var stream = ...;
var writer = new JsonWriter(stream         


        

Answer 1

Turns out I needed to Google for a bit longer.

JSON.NET does indeed support this via its JsonWriter class.

My example would be written:

Stream stream = ...;

using (var streamWriter = new StreamWriter(stream))
using (var writer = new JsonTextWriter(streamWriter))
{
    writer.Formatting = Formatting.Indented;

    writer.WriteStartArray();
    {
        writer.WriteStartObject();
        {
            writer.WritePropertyName("foo");
            writer.WriteValue(1);
            writer.WritePropertyName("bar");
            writer.WriteValue(2.3);
        }
        writer.WriteEndObject();
    }
    writer.WriteEndArray();
}
