Can RestSharp send binary data without using a multipart content type?

Question

I have been using AddParameter to include XML bodies in my HTTP requests:

request.AddParameter(contentType, body, ParameterType.RequestBody);

I had the same problem, but I didn't fancy forking the code and I didn't like the alternative suggested by Michael as the documentation says "RequestBody: Used by AddBody() (not recommended to use directly)".

Instead I replaced the RestClient.HttpFactory with my own:

RestClient client = GetClient();

var bytes = await GetBytes();
client.HttpFactory = new FactoryWithContent { GetBytes = () => new Bytes(bytes, "application/zip") };

var request = new RestRequest();
return await client.ExecutePostTaskAsync(request);

Where Bytes and FactoryWithContent look like:

public class Bytes
{
    public Bytes(byte[] value, string type)
    {
        Value = value;
        Type = type;
    }

    public byte[] Value { get; private set; }
    public string Type { get; private set; }
}

public class FactoryWithContent : IHttpFactory
{
    public IHttp Create()
    {
        var http = new Http();

        var getBytes = GetBytes;
        if (getBytes != null)
        {
            var bs = getBytes();
            http.RequestBodyBytes = bs.Value;
            http.RequestContentType = bs.Type;
        }

        return http;
    }

    public Func GetBytes { get; set; }
}
