Generating newlines instead of CRLFs in Json.Net

Question

For my unix/java friends I would like to send newlines ('\n') instead of a CRLF ( '\r\n') in Json.Net. I tried setting a StreamWriter to use a newline without any success.

I think Json.Net code is using Environment.NewLine instead of calling TextWriter.WriteNewLine(). Changing Environment.NewLine is not an option because I'm running as a server and the newline encoding is based on the request.

Is there some other way to force newline for crlf?

Here's my code -

using (var streamWriter = new StreamWriter(writeStream, new UTF8Encoding(false))
{
     NewLine = "\n"
})
using (var jsonWriter = new JsonTextWriter(streamWriter) 
{ 
     CloseOutput = true, 
     Indentation = 2, 
     Formatting = Formatting.Indented 
})
{
       // serialise object to JSON
}

I see several solutions here that are configuring the serializer. But if you want quick and dirty, just replace the characters with what you want. After all, JSON is just a string.

string json = JsonConvert.SerializeObject(myObject);
json = json.Replace("\r\n", "\n");

I know this is an old question but I had a hard time getting the accepted answer to work and maintain proper indented formatting. As a plus, I am also not creating an override to make this work.

Here is how I got this to work correctly:

using (var writer = new StringWriter())
{
    writer.NewLine = "\r\n";
    var serializer = JsonSerializer.Create(
        new JsonSerializerSettings
        {
            Formatting = Formatting.Indented
        });

    serializer.Serialize(writer, data);
    // do something with the written string
}

I am assuming that the code changes referenced in this question enabled the setting of NewLine on the StringWriter to be respected by the serializer.
